I am currently running the 7.5 rough country with 35 1250 18 trail grapplers and my truck rides rough as hell. Ive got a buddy with a 6in fabtech and his rides like a caddy with the same size and brand tire only in a 20. I am just wondering what the difference is. Both have strut spacers only at different locations. I think the fabtech kit has a block and helper spring in the rear but I thought that would ride rougher. If I cant figure out how to soften up my ride im considering taking the rc off and ordering the fabtech unless you guys got any suggestions. Also dont know if its relevant but the stock bumpstops are still in place and the rc directions said to cut them off. Thanks for any help in advance.

Replace the RC shocks with bilstein. Also if your control arms are riding on the bump stops you will have a terrible ride, cut em off or get cognito UCAs.

My uca is about a finger width from the bumpstop. Are the cognito arms comparable to the arms that come with the rc 3.5in kit as far as being angled or curved. Also with the additonal travel of a new uca will the suspension "overflex" and start ripping boots or binding cv shafts.

If your not on the bump stops don't worry about the UCAs. Better shocks will be the best bang for your buck, also over inflated tires ride rough, what PSI are you running?

i am running 35 psi all the way around. i was told that was as low as i could go without making the tpms go off. i noticed you have the rc 7.5 on your truck. did you cut your bump stops off or are you still running them.

Cut them off. Ride is worse than stock, as to be expected with a budget lift.

I would replace the rear, first, I think they are cheaper. If that has you where you want to be, good. If it is only some better then do the front.

I had the RC 3.5 lift on my '08 Sierra, it was pretty bad with the RC shocks back there. I put a small lift on a '09 titan, and put Rhino rear shocks on it and it was not that much better, than RC.

I would go with the fine German engineering, that you get with Bilsteins.:ninja:

I'm running the 7.5" rcx with 35x12.50x20s and bilsteins front and rear and my truck rides better than stock. Especially over bumps. I'm running my tires at 35psi as well, but think that might not be ideal for tread wear. Might need to go a bit lower.

Get the front and rear bilsteins and install those and you will be very happy:imo

Contact Jon at Southern Truck Performance (vendor on here) and I'm sure he'll be able to help you out. He was able to answer ALL of my questions when I was pricing everything out.
