Do I need this part?

Submitted on 2011/06/24 at 4:53 am

I am lowering (2/2) my 2001 S10 RWD. Looking at your website I am a little confused about the pinion shims (1023BP) – the website says they are required for 3″ and 4″ blocks. If I use the 2″ steel blocks (SB2LK) do I still need the shims?

The 1023BP is for the aluminum blocks on newer S-10′s. The leaf springs are not flat where the blocks mount and you can crack aluminum blocks when you tighten them up. With the steel blocks you want to use you don’t need the 1023BP!
