If i have spring tech 3.5" spindles now, What parts of the 7.5" fabtech would I need to get the full 7.5"?
Or would i need the whole kit still?

 

The fabtech is spindles, shocks(front and rear), bigger lift blocks then the springtech kit and I believe that's it.

 

Oh and you can't turn the springtech 3.5 spindles into a 7.5 spindle. You gave very vague details.

 

The fabtech kit is the spindles, lift springs, and lower drop crossmembers. Then it comes with blocks for the rear end. Your probably not going to find the parts and be able to piece it together. It would be better to use the full fabtech lift and then sell your current spindles.

 

Just so you know the fabtech kit isn't a 7.5" spindle. It combines a lift spindle, coil springs, and a drop crossmember to achieve 7.5".

 

Oh my mistake. Thanks for the info.

Either way I wouldn't bother pieceing a kit together. Do it right.

 

Just put out the money for a fabtech kit. Piecing together different kit parts is never a good idea unless you've scrutinized the specs to know nothing would conflict. Trust me, you will spend more to fix the truck after you've pieced stuff together, rather than buying one complete kit.

 

Thanks guys!
Answered my question very well.
