Question about leveling kit on 2015 sierra

Cisbell760 · January 10, 2019

I have a 2015 GMC Sierra 1500 4x4 (not z71). I bought the truck used and it already had a leveling kit installed. As far as I can tell it is an over the strut 2”. The truck rides like I’ve cranked torsion bars up on an older model truck. It rides terrible. My previous truck was a ford and I installed a 2” rc kit on it myself over the strut and it didn’t ride any different. I’ve had the front end aligned which it needed and it did help very slightly. My question is (and I don’t think there would be any difference just want some opinions) would there be any difference in ride between the over the strut and the u-shaped kits that mount to the bottom? A half inch spacer is a half inch spacer no matter top or bottom IMO. Is the bouncy ride caused by the factory shocks and suspension not being the rancho being over stressed? I have buddies with the same truck but with the z71 package with 2.5” kits that ride better than mine. I’ve looked at getting the rancho quicklift leveling struts for the prices and ease of installment. Any recommendations or information is appreciated!

the stock ranchos suck. Look into the bilstein 5100s, they lift up to 1.85” and are about $200-$220 a set. The ride is much better than the ranchos.

Bilstein 5100 at the high setting (1.85). Get rid of the leveling blocks.

The ride is way better.

Rancho shocks were terrible on my truck!

Thanks guys I appreciate it! I had previously looked into the bilsteins but had almost decided to go with rancho quicklift just for the easy installation. But from what I’ve found the ride quality just isn’t going to compare to the bilsteins and for the money I believe I’ve made my decision. Thanks again
