i put my RK Sport upper and lower mounts in today. I noticed that i get alot more pickup. Overall, i am glad that i got these and i would recomend them. Also i dont have all that much vibration in the cabin.
glad you like them
Im a Xbox 360 fanboy...and damn proud of it!!
Just remember to torque the bolts to spec.
74lbs on each + a 90 degree turn, stated in the GM manual, i did that too mine and little to no vibes at idle. Only time you can feel it is i take off kind of slow and only until the rpms hit about 1700.
