Lift Block Question

[Kody]

I have the Skyjacker 3" lift kit for my '02 Silverado. The kit comes with a 2" rear lift block that you stack on to the factory 2" block. I need another 2" of lift in the rear to compensate for torsion crank and I do not want to put an add a leaf in. Should I look for a 4" lift block plus the factory 2", or should I put a 6" lift block in and take out the factory block.

 

Anyone have recommendations on specific blocks?

I don't think anyone makes a 6" block, I have a 5" BDS block along with an add-a-leaf on my truck. Most companies do not recommend stacking blocks even on top of the factory block but if you have to then go with a 4" block on top of your factory block or remove all blocks and install a 5" block with an add a leaf.
