Hey looking to put 35"s on a 2020 trail boss... Local shop said I would need new rims and a 6" lift kit...???? If so is there anything I need to know about what type/ kind of lift to go with to avoid future issues..looking for some product recommendations.. don't care for the way these trucks sit stock, tires seem small????

I would probably do more research on here first before deciding. There are many people on here who have 35" tires with just leveling kits or slightly higher. Your trail boss also has larger wheel openings to easily allow larger tires compared to my AT4.

You fit 17's on this truck?! Hallelujah! I've been searching far and wide to find a 17" wheel that fit these trucks. I didn't think I was going to be able to! Any specific backspacing to look for? Did you do any trimming?

 

While we're at it- Any power loss/MPG loss with the bigger/heavier tires? Do you have the 10 speed trans or 8 speed?

 

Great looking rig. I've got the same one!

Ya brother they fit no problem.  They are the icon compression wheels.. I just looked them up and they are actually 17x8.5 0 offset 4.75 backspace.  I did have to trim the mud flap a little and remove the flap bracket.. I used one of the bracket bolts to pin back the fender liner and it doesn’t rub lock to lock.. was happy how it came out with very minimal mods to make it fit..

 

as far as power I’m not sure the difference as I put the wheels on a few weeks into buying it.. although I’m positive I lost some MPGs and some pickup.. regearing is an option but it’s not really noticeable and I’m not racing the truck around anyways.. 

 

I was actually thinking down the line if I do long travel and fenders, I’d go to 37s and def regear.. but that’s more a dream than a reality..

The icon site has a photo of a T1 with these wheels so that’s how I knew they’d fit..

I like more tire too. 17x8 methods 0mm no spacers.

Truck looks great, do you have a leveling kit or small lift on that ?? Do you have any rubbing issues??

I have the Eibach pro truck struts and springs in the front. I have them set on the third strut perch. The rear is the TB blocks that came on the truck and the Eibach struts. I’m around 3 inches in the front and 2.5 in the rear.
 

I trimmed the mud flaps and removed the bracket, no zip ties though. I don’t have rubbing even on flex in the front but I’ve trimmed all the places I was rubbing before so you have to be willing to slice the liner a bit.

I have a 2020 Custom 4x4 (Not a trail boss). I added a 2.25 procomp level up front and was able to fit 35x12.5s on my stock 20’s. I did delete the flaps/air guards, but have no rubbing even at Full lock. 
 

I had two different (reputable) 4x4 shops say something similar to me about needing a 6” lift to get to 35s. Guess it’s in their best interest to have you spend $2500 getting a Massive kit installed and selling you a tire package for another $2500. Also to be fair to them, ( at least the ones around here) they aren’t very familiar with the T1s yet 
 

I have the tires and stance I want and am all-in for less than $1400

      What have you done to your K2 today?

      By UrbanRage · Posted

      I have the same running boards on my truck and I do agree they are bulky. I also find myself stepping over them when getting in and out of the truck. Besides providing protection to the rocker panels, they aren't very useful.  I will be replacing them soon with the Amp Powersteps.

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

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

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.
