2014+ Leveling Kits

mmwest · July 25, 2016

I have a newly installed complete 2.5" RC level kit and my truck rides pretty rough. Now when towing my boat (#3400) the truck bounces going down the road.

At first I thought I needed to change my tongue weight which I did by swapping receivers from a 2" drop to a 4" drop which put more weight on tongue. That sucker still bounces and is driving me crazy. If anyone has experienced this or may know how to correct it I would definitely appreciate your input.

I have had so many issues with the dealer and the 2.5" level kit they installed and now this bouncing crap. I am regretting not going with the Bilsteins and wondering can I add them now to help the ride.

This sucker rides like crap........................especially for a 50K truck.

I've noticed mine bounces as well but only on concrete highways, when it is asphalt I have no issues. My buddy seems to think it's bc of the curve in the concrete sections and the length of the wheelbase on the truck along with the off road suspension. It creates a perfect storm for this bouncing crap. Have you noticed it on concrete highways only?

Same ride with mine and the 1.5" level and alignment, if it helps or matters. .

I haven't really noticed the asphalt thing but mine seems to do it all the time. I don't see how it would be something only in GMC's w/wheelbase.............................hell.nobody would buy em or we'd be seeing thousands of post like mine. Thanks for the feedback though.

I have the RC 2.5 kit with the rear block and I have been considering adding Firestone airbags, as I have had them in the past and like the added capacity and safety. My question is will the standard kit work or would I need some sort of a spacer due to the 3/4" taller rear block. I think the answer is no but was curious if others have considered this. Thanks, Luke.

Just finished mine on my 2016 Z71.... Didn't even remove the wheels... Just dropped the lower shock mounts and the sway bar links. Used some pry bar action and was able to get everything installed. Had to cut the bolt underneath the CV joint tho. Was a little too long.... 2" RC kit.

Yeah the bolts are supposed to go from the top down. I was going to do the same with mine or buy a shorter bolt. Called rough country and they explained bolt down for safety reasons if the nut was to loosen your strut could slip.

Which is better installing a spacer under the strut or on top? Does it make a difference? I am sure under is easier to install but what about ride quality?

I think the top is supposed to be the best. But the kits I looked at installing said you have to cut the strut mount bolts. So I went with a lower. It rides fine but that's subjective.

If I went to a 3" lift in the front do I need to do the diff. drop?

What rear block do you have, the RC 3 inch? Did you get longer rear shocks or shock extenders?

Looks good.

I have 3 inch front and 3 inch blocks in the rear. Its good insurance to get the shock extenders. Get the readylift extenders. They have a sleeve in them to keep the bracket from being crushed when tightening it up. I didnt do a diff drop on the front. I'm sure the 1 inch spacers rc sells I could do just don't know if any grinding off the case would be needed. As is now she rides just like stock but looks a crsp ton better

I put a 2" block on top of the stock 1" block and I used the extenders
