RC 3.5 Knuckle Lift Kit with front shocks

TXGREEK · April 15, 2019

How's everyone's lifts doing? I bought a 2018 Sierra about three weeks ago and have been looking into lifts pretty much ever since. Too much to decide on! I'm on a budget, but I'm willing to wait if something will last longer without needing repair. Thanks!

Go with CST 4.5”-5” lift, excellent super quality lift kit with zero negatives. Keeps stock width and turning radius even allows keeping your stock wheels up to 35” tires.

The kit was $500 and the install was $700. There is some, but minimal cutting involved in the installation.

According to Rough Country, when running the stock 20x9 +27 wheels you must use 1/4" wheel spacers or the tires will allegedly rub the control arms. I did not verify that.

I did add 1/4" wheel spacers essentially making the tire and wheel package "fit" as 20x9 +21 wheels. Obviously, the stock 275/55r20 Goodyear Wrangler SR-A tires fit just fine with days of clearance all around.

I'm currently sitting at Discount Tire getting 33/12.5r20 (approximately 317/50r20) Nitto Ridge Grapplers installed. These are slightly larger than Rough Country's recommended MAXIMUM tire size, 285/55r20 (32.3/11.2r20)

I'll update y'all on any clearance issues when I'm done here.

Im pretty sure I read that too.. but I threw on 285/55 22 and rubbed only on the sway bar being it at full lock, not the control arms. Just a slight rub.

Anyone else looking a this kit.. iv had it on the truck for prob. 30k, 40k miles,. When we get snow I just throw it in 4wd and it doesn't sound any different then when it was stock.

When I installed this kit a while back, I'm pretty sure the knuckle itself was taller but not by much, maybe 1/2in, 3/4.. I could be wrong, maybe,... but I did notice the lower ball joint spot was angled down vs oem was flat to help with that angle.

So far so good for me too. 40k hard road miles with occasional off roading on easy to moderate trails. Creaks a bit, but alignments aren't too far off spec. Lifetime alignment from Firestone is worth it for these gm trucks - no question. ...especially with any suspension mods.
