CST coil overs and Method wheels installed

CWilliams · January 30, 2020

I just installed these coil overs yesterday and hoping you guys could give me some input. They are supposed to come set at 2”. I got them put on, let the truck of the jack and it lifted the front end almost 3.75”. The coil overs are only supposed to be between 1”-3.5”. I lowered them to the lowest setting and they only went down 1/4”. I called up CST, sent them pictures, told them everything and they basically said I didn’t measure right and it’s “impossible”. I even sent them pictures of them adjusted all the way down which they confirmed should only be 1” of lift. Does this look like only 1” of lift to you guys?! Lol. The alignment shop used 4 wheel computer and said everything lined up fine. I think the angles look OK, but was wanting some other eyes to see it y’all notice anything weird. Getting that much lift, I’m definitely going to look at UCA but still it doesn’t look bad to me. Used a 2.5” rear block and Bilstein shocks. Wheels are 20x10 -24 Method 605 and tires are 275/60/20 Ridge Grapplers. These wheels would NOT clear even with a 1/4” spacer. Luckily the shop had some 1.5” hub centric adapters, still had to trim the tips off of the stock studs. But it rides awesome and absolutely no vibes up to 75-80 mph.

Looks awesome, but dam that sucks that the wheels don't fit. I'm going to need to test fit my Hostile wheels

Yea I actually installed them Tuesday not yesterday. Drove around about 30 miles or so. Then yesterday drove it up to the shop. It only settled maybe 1/8” as best I could measure it.

Did you put new UCA on?

This is from my AT4 4" lift, which I believe is 6" lift from non factory lifted trucks.

Flatblack83 · January 30, 2020

Those coilovers have little to no preload, I shouldn't sit that high. At that setting it should be at its lowest heigth being like 1-1.5. My icons set at 3 inch have my fender height at 41 inches. The above post is 44 with a 6 inch so that's about right. Measure what your fender height is and u will know for sure.

I’m sitting at almost 41.5” with the 33” tires. I know it should be a lot lower with my setting, that’s what I’m trying to figure out. And either CST knows it’s not right or they really think I’m dumb enough to not read a tape measure. My stock measurement on the front was right at 37.5”

Measure the coil over from the top mounting plate to the bottom eyelet mount (unweighted) and let us know what that measurement is. Then we can help verify to see if anything is off there.

Also, super weird about your wheel fitment. These trucks have proven to be picky. On a 20x10 wheel usually people need to run a 5mm spacer only if the offset is around -18. If you’re -25 on a 20x10 you’re typically golden. So must be that specific wheel. But glad you got it mounted up one way or another

Also, for reference, my coil overs designed for a 6” lift were 28 1/2” fully extended.

I will have to get the jack back under it and measure tomorrow, but I’m sure you have a diff. drop and new spindles so the measurement you have may be irrelevant since I didn’t change those parts.

And yes I was disappointed the wheels didn’t fit as is, didn’t want them poking out so far. But they had some 1/4” spacers and I looked at it, still needed at least another 1/8” to a 1/4” to clear. Is what it is I guess.

True, good point. I do have new spindles supplied with my kit. You could still compare to some factory struts though

Ready lift does make a 1/2" spacer should work

Here is my stock AT4 - 2" from factory - it sits at 38" +/- in front and 40" +/- in the rear - so 2" of rake. I have a Ready Lift SST leveling kit going on next week - so will post comparision pictures.

Truck looks great! I was curious how you still like the setup, ride quality...etc.. How was CST customer support while you were working through your questions? Also it looks like new UCA were not required...any issues? I have a 2020 GMC Sierra Crew cab 4x4 3.0 diesel and thinking about going the same route. Wanted a 6” BDS Coil over kit, but it won’t be available for a few months. Local shop here in SoCal really pushing this CST kit...Anyway...thanks in advance!

Thanks! I am still liking the ride quality, no issues at all. Yes, still running factory UCA and haven’t had any issues. My only complaint was the ride height was not as advertised. I got on the top end of the advertised lift and I have the at the lowest setting, so if you’re looking to go less than 3.5” or so, I wouldn’t get them. Customer service tried to work with me, but basically said it is impossible for me to have as much lift as I got with them lowered all the way. Sent them tons of pictures and they pretty much stopped responding. But at the end of the day I’m still happy with everything.
