Adding Bilsteins 5100 and Leveling kit Right?

Hi there. I've been reading upon forums and getting advice from people who have Sierras (2018).

 

I approved a quote that the shop locally is going to do. I have requested a 2" leveling kit to be added, and some people have recommend just adding bilstein 5100s and using them to raise the front of the truck to get close to level. Should I tell the shop to not do the leveling kit, and just add the bilsteins with the height adjusted to get close to level to the rear? Or should I have them both added? (Will that benefit?)

 

I am adding 285/55R/20 Falken Wildpeaks (AT3W) over the factory elevation rims and I'm excited for those. Just a little confused with my understanding about whats above.

Again, I've done mostly just research on this, I'm not a Truck/Car Mechanic, I prefer to hide by my desk in IT 😂

I know some aren’t going to like this but yes go with the 5100. Add some height and also plant your ride more. Get some for the back too

Do I need a leveling kit? Does that even help it? or just tell the shop to do the 5100s and lift them from the front

If you have 5100s that are capable of adding lift to level the truck, Why would you set the 5100s at stock height and then add a leveling kit? (Which is presumably some spacers that are meant to go on the stock strut)

I used the 5100's set at +2" to the front of my 2022. increased the tires size from 275-60/20 to 275-65/20. Tires are an inch taller at 34" vs stock 33" The combo raised the front 2.5" and the rear 0.5".  Truck is perfectly level. The Body style for the 2019-2022 makes it look a little front high sometimes so I'm adding 1" rear blocks this week to give it just a little rake.

No other leveling kit was added (i.e. spacers) I think the shocks are the way to go for leveling and there is no need tor spacers unless you want to go higher. The pic is how it currently sits with out the rear blocks.

Just go with the 5100s in front and back, no need for additional leveling.

Appreciate gents. That's what I thought as well, didn't make sense for me. @Dirk13 But I called up the shop, and stated that I wanted to remove the leveling kit, and just do the bilsteins, adjust the front to be as close to as level as possible with the rear.

 

The installation date is tomorrow. @pepe48134 your picture in another post inspired me to add them as well. I'm wrapping them are 285/55R/20 Falken WildPeaks AT3/W. It should look pretty spot on. I've already taken before photos as it sits.

Should you still do new UCA's with the shock based "lift" to avoid UCA failure like we see with many level kits when people don't replace the factory UCA's?   I'm guessing not since all it's doing is adding spring preload stiffening the ride to get the extra height as opposed to a spacer lift.

For me rule of thumb is the most you want to go is about 2.25 without starting to stress things out. Maybe even 2.5 but thats it.

It doesn't stiffen the ride at all the springs are liner rate. This is what the trail boss (2" factory Lift front and back) does and they use the same UCA's

Just wanted to thank everyone! I went withIMG_2472.thumb.jpg.a6df1ae96144793f7462bb6ced0a49f0.jpg the bilsteins and new tires. And it rides great and looks amazing. 

 

The extra lift in the front makes a huge difference. Thank god this actually feels like a truck now!

I don't think that's quite how it works, a linear rate spring only means the spring rate increases evenly throughout it's travel, it doesn't mean that the spring has the same force throughout it's travel. So if you crank up the preload and raise the front end height it's going to stiffen the ride.   The plus side is usually the aftermarket shocks (fox, billstein) are so much better than Rancho's no one notices, especially if you get the strut with the fox/bilstein matched springs.  This is why strut spacers tend to maintain a factory ride better than height adjustable struts.  That said, there are some other significant cons to spacers if your vehicle actually leaves the pavement and overall I'd say the adjustable height struts are a better option, of course they are also significantly more expensive, especially if you don't reuse the factory coil springs. 

 

This site does a very good job of breaking down the pros/cons of spacers -vs- height adjustable struts.

your correct the spring doesn't have the same force throughout its travel,and in theory increasing the preload will make it stiffer. However the bilsteins are designed for the lift and the ride is actually better than stock. The linear rate springs make it easier to deal with the preload vs progressive springs. THe other big pluss is the stock suspension travel is maintained with the height adjustable shocks vs spacers.

      Towing In Loose Gravel

      By Z45 · Posted

      Having owned 4wd vehicle since the 1970s I find there are varying opinions on how to use 4wd, every owner is an expert in their minds.  IMO, 4LO is the appropriate gear and what I would use,  You have to feather the gas to avoid spinning tires and the lower the gear the better chance.  But like I said you will find those that think their method is best.  I live near a boat launch.  Yesterday there was a new Ford Maverick pulling out a pontoon boat almost 2x its size, they had no problems and they don't have a LO range.   True story. One winter day not long ago I was coming out of small town post office and there was a F150 4wd parked in front and was stuck foot deep snow ruts. I knew the lady so I asked her to put it in 4wd (wondering why in the middle of a 2-day snow storm she wasn't).  Her reply surprised me, "my husband" (the expert) told me not use that because it uses more gas. She finally got unstuck spinning in 2wd which likely used more gas than not.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.
