shuttering problem during take off

[outrage]

I had my truck lifted with a pro comp 6.5 lift. I notice now when I take off it shutters almost if the transmission is slipping. What could this be?.........Terry

drive line vibration, with a 6 inch lift , probably need somewhere around 3/4 of an inch of spacing between the center support bearing and the frame where it bolts up, there should have been a spacer with the kit , even if it was installed it may not be enough , this is a very common problem when one is lifted , look under the truck at the rear driveshaft and see if it has a spacer installed at al on driveshaft center support bearing

yes there is a spacer at the center of the driveline carrier bearing support. Would it be safe to say it needs to be shimmed some more. should this be covered where I had the lift installed?

Thanks

well the place that installed it isnt really responsible , the lift company sent the piece they thought should be sufficient but every truck is different , may want to space it some more , how thick is the spacer , you can also go to far

with mine i bought the pro comp carrier bearing kit that came with diffrent size shimes so you can add remove diffrent sizes untill you find the sweet spot and it goes away
