I am currently running Mickey Thompson 33x12.50R17's on a stock Rubicon Unlimited suspension. I am scheduled to have Daystar 2" spacers and Procomp Shocks installed, keeping the stock springs. I am worried that this will not be enough to allow for full flex in the suspension.

Also, I would like it to be at the fullest of it's capabilities with the 33" tires. With that in mind, how much of a difference does it make using spacers rather than a coil spring lift kit?

Any insight is greatly appreciated!!

 

Springs always work better than spacers. You will need to trim fenders or increase bumpstops if you disconect. I rub pretty bad disconnected and crossed up when off-road.

 

Coils will give you more flex, but your drive shaft will be safer with spacers. I don't rub at all with 35s and 2.5 tf coils
