I just bought a belltech lowering kit for my truck with shocks and coils, I was wondering do I need to get new spindles?

 

I did the 4/6" on my 454SS and it required the 2" spindles, 2" springs and 6" flip kit in the rear with the c-notch. Also, i got 4 belltech nitro-active shocks. I would have just got the 2" spindles if just lowering 2 in the front, a lot easier to install. But no you dont need new spindles for just changing the springs. Hope i helped.
