SL3, SL4, & FSL
 
SL3                   4.6lbs.                     FSL
 

We stock the affordable FSL and the upgraded Super Lite 3 & 4. The FSL is a direct replacement for the SL2, each body is stress-flow forged and features one bridge bolt. The FSL works excellent on the rear of pavement cars with 1.38" or 1.12" pistons. For tougher applications we suggest the SL3 & SL4. The SL3 is similar to the SL2 but has added heat shielding, staggered piston sizes and a beefed up casting. Both versions use stainless steel pistons. The SL4 is a replacement for the SL3 featuring improved design produced by finite element analysis, solid modeling, and stress analysis technology. All Wilwood calipers are available with their Thermlock pistons to protect from heat transfer.

Wilwood's new caliper in the Super Lite line is the Billet Six Piston (BSL6). Made to fit the standard 3.5" SL mounts. The three different sized pistons provide even pressure for extended pad wear. Require a special Wilwood pad.
