Hey I have a 2001 2wd Screw and would like to put a 3.5" spindles on it. Any suggestions for the brand to use? Also do i need to, or is it recommended, to upgrade the shocks as well?

 

Doestch and CST are probably your best bets. And upgrading shocks is always a great idea.

 

I'd say Springtech or Doestch. They're the same spindles but usually the springtech one's are a bit cheaper even though they'll most likely still come shipped in a Doestch box.

As for shocks, just remember you still only need stock length shocks with lift spindles.
