Which 2.5" Coilovers Would You Pick?

Curious what everyone's opinion is on the different brands of 2.5" coilovers for the K2 trucks. Truck is currently setting on a BDS 6" lift with the rear leafs and Fox 2.0 rear shocks. The front shock/ strut is the standard one from BDS. I've never loved the way it has rode and I'm looking at possibly upgrading by the end of the year. 

 

I've been eyeing the RC Vertex coilovers and the Fox 2.5 Factory Series coilovers. Naturally the Fox coilovers are what are offered through BDS as an upgrade when you purchase the lift.

 

Between those two (or if there are other options available such as King, Icon, etc.) which would you pick and why?

 

The price point on the RC Vertex coilovers is a huge plus, so is it worth the extra coin to go with the Fox coilovers? They would match the rear shocks I have, but I'm not terribly worried about that.

 

Truck is mainly a pavement princess. Only time she sees dirt roads is when I go shooting over at the farm, and gravel roads are also not very common for me. Just looking to improve the on road ride of this thing.

It looks like the Vertex coilovers come with a 3 year warranty and the Fox only come with a 1 year warranty. Seems like another win for the Vertex, although I don't see either of them failing within 5 years of install.

 

Really leaning towards the Vertex at $1300 compared to the Fox at $2200 (cheapest I've found them so far.)

 

Hopefully someone here has some insight into both of them and pro/ cons of each.

 

Really looking for the best on road ride and street manners (without reaching too far into the pocketbook lol)

I have no experience with Vertex. I have had fox 2.0 on front and back of my 1500 3" lift for 60k+ miles. I like the on road manners a lot. Soft enough to be smooth ride, firm enough to provide control (1000x better than factory). Offroad, I have no complaints. They maybe bottomed out once hitting a dip at speed, but no big deal, and handle everything else I need.

 

My son put Fox 2.5 on his jeep XJ (unibody and very light). He loves them, but too rough on pavement for me. Long highway trips are jolting, but bearable. 

 

Looks wise, the Fox 2.5s are much better, and his has reservoirs which are even more flex looking.

Also seems like the Vertex are not rebuildable. Definitely a huge con. May just be worth it to go with the Fox coilovers so I can rebuild them in the future when they wear out. Truck already has 172k on it but I plan on keeping it for a while still. Decisions, decisions...

I just installed fox 2.5 dsc front and rears on 2018 silverado. Still working on the review/ dialing in phase but I might be able to assist with insight?? this is an older thread so im assuming you already updated suspension??

I have not. Ended up having to replace the catalytic converter in the truck and now I’m waiting on a replacement rack and pinion to show up so I can install that. So, upgraded struts have been on the back burner for now. I still do like to look at them though, just to get an idea on price.

 

I’ve definitely been leaning towards the Fox 2.5 DSC’s. Let me know your review on them once you get them dialed in for your truck. At this point, it’ll be either a next year or following year project.

Hello, just signed up with these forums to be able to get in on this good convo. never been in a forum nor ever used social media so take er easy, ha.  just finished my truck and am in the dialing in/finding my preferences/review phase. First truck ever and first time spending some hard earned cash to try and do things right the first time (in moderation, cuz the money tree wasn't flourishing, ha). Cuz I'm good at breaking things. I wanted to get some feedback from you folks as now would be the time to make any adjustments. here's the trucks stats:

2018 silverado, 5.3, 3.43 gearing (bought new)

put 20 in wheels with leveling kit initially, but now that Ive learned more about off roading I wanted to go with more of a legit setup. I realize that the fox 2.0's are more practical for my application - light off roading but like i said Im good at getting in over my head when playing and without having multiple trucks to actually go out and drive and feel, I figured like my 16 yr old says, YOLO - you only live once. I blew too much money and went with the DSC's. I figured I would be happier down the road with an adjustable shock and a rebuildable one also.

1) 285/70r 17 - c load ( wanted to g with c load for a more forgiving side wall 

2) black bear tune (stock acceleration was depressing, and was shocked when I learned about the price to lift a truck the right way- basically I didn't want to spend money to re gear this truck for bigger tires) (i do enjoy the tune, by the way. expensive but brings a smile to my face every time i accelerate, and got rid of AFM (V4 option), and the clunking when dow shifting)

3) fox 2.5 dsc front and rears from Accutune (waited 1 yr for these products) 

4) deaver mini pack - progessive payload spring replacement, (lifts the rear approx 2 in) can remove bottom "stackers" for hight adj if needed. I wanted a rake for towing and or payload 

5) UCA replacement - went with icon delta joint _they had sent the wrong part, so had to go with kryptonite during install but am second guessing krytponite at the point - will discuss in pics below

other minor mods you can see in pics (ceramic coating, SDHQ skid plate)

still stock. Wanted to keep a rake on the truck with new setup so front tires aren't "floating" when pulling or hauling my dirtbike with loaded bed.

truck after new suspension is installed, sits 2 in taller in rear and taller in front with rake (not sure lift height diff in front) 

but i wanted max function with front coilovers so they are set as such according to accutune and fox which is 18.66 in from top hat to bottom bolt of coilover. These coilovers have a 0-3 in adjustability, I beleive fox says max height for function is approx 2.25in.

icon delta joint was ordered to be used but they sent the wrong part so for a quick fix and me being impatient after waiting a year for suspension, i went with the install shops quick fix of the kryptonite UCA. but looks like a tubular UCA would glide against the hose as opposed to eat into it. fox says with the resi hose being where its at, it limits control arm movement. hmmmm.... me no likey. 

So thats where im at

 

overall, the verdict on the review of the suspension feel and drivability is not out yet. I wont comment too much as I haven't used mine much. definitely not long arm travel like a side by side. And it seems that faster = smoother over the rougher stuff. 

 

 

some of the guys I work with have similar setups. So once mine is dialed in. I will let them drive my truck as I will drive theirs for comparison. But it will not be an apple to apples comparison. 4 runners, diesel setups, 2.0's, etc....... 

 

I'm curious of your input and feedback. Please and thanks

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      Have considered installing a DC to DC charger in your camper to replace your isolator?

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.
