Rough Country 6" lift shudder

I know this has been brought up before but here goes again. Installed the 6" lift on my 2013 2wd SL and now have a shudder on take off. If I leave slow it does not do it but if I get on it in anyway it is there. Seems like driveshaft angle but RC says I need traction bars. What do you guys say?

they are correct. you need to follow up with additional mods to straighten it out.
you also may need an pinion angle shim if the bars don`t stop it.

Well I guess I need to do some more shopping. Thank you

I installed the RC traction bars with PRG upgraded hiems, and mine behaves much better. Mine is not lifted, so no pinion shims needed, although I did check my driveline angles with an inclinometer when I was troubleshooting my shudder/shaking/driveline vibration issues. Check your angles, then install traction bars and pinion shim if needed. That should iron out your axle wrap issues.

you definitely need tractions bars! i was in the same boat as you with my 2wd LWB when i first installed my 8" lift. from a dead stop and just pressing the gas like normal the back end would shake/vibrate. i felt something was eventually gonna break! so for awhile there i had to ease of the gas pedal when i moved forward. after much research i invested in some traction bars. CJD to be exact as he was able to custom make mine since i'm LWB! biggest mod improvement and i love to this date!

a 1 degree shim helped mine out. Tried the .5 and 1.5, but 1.0 degrees worked best.
