Description

Wilwood Forged Superlite 6 radial mount calipers are the go-to calipers for all types sustained hard braking on dirt and asphalt ovals, as well as a wide range of off-road, rally, and road course applications.

The FSL6R calipers offer exceptional strength and reduced weight due to the stress-flow forging from premium grade aluminum alloy billet. Each caliper features closed end bridges with a radial transition down to the main body and piston bore housings. The elimination of machined steps and sharp shoulders in this critical area provides a measurable increase in overall body strength and resistance to deflection under load.

They have been redesigned with internal fluid ports that eliminate the external fluid crossover tubes. The transfer tube has been replaced with two additional bleed screw assemblies which allow differential bore models to have a left hand and right hand orientation, but no leading or trailing configuration is required.

FSL6R/ST calipers provide the pad wear performance advantages of differential bore pistons with the option for ultimate heat protection using Thermlock pistons in the ST models. Differential piston bores compensate for leading-edge mechanical loading and temperature variances across the pad face to reduce pad taper wear in sustained high-temperature applications.

Thermlock pistons in ST caliper models block heat transfer from the pads and reduce temperatures in the caliper, fluid, and seals by up to 25 percent over standard stainless steel pistons.

Wilwood Forged Superlite 6 radial mount calipers are available with either a Quick-Silver Nickel or Type III Ano (hard anodize) finish.
