Wilwood Caliper-Forged Superlite 4R-R/H 1.88/1.75in Pistons 1.25in Disc

The Superlite 4R caliper series is the benchmark in asphalt short track, late model, modified and open wheel competition. It also enjoys prominence in a variety of road-race, rally and sport driving applications. The new FSL4R model series is the latest innovation to this Superlite family of calipers. It has been redesigned with internal fluid ports that eliminate the external fluid cross-over tubes. The transfer tube has been replaced with two additional bleed screw assemblies which allow symmetrical piston bore models to be mounted either right or left in a leading or trailing position. Differential bore models still require left hand and right hand orientation, but no leading or trailing configuration is necessary.

Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only. If you’re unsure about what’s included with this product, please contact our team for clarification.

Brake Caliper, Forged Superlite 4, Radial Mount, Aluminum, Gray Anodized, 4-piston, Passenger Side, Each

Engineered to deliver the pad wear performance advantages of differential bore pistons, Wilwood forged Superlite 4 radial mount calipers also provide ultimate heat protection in the ST models. The differential piston bores compensate for leading-edge mechanical loading and temperature variances across the pad face. The Thermlock pistons in the ST models block heat transfer in the pads and reduce temperatures in the caliper, fluid, and seals by up to 25 percent over standard stainless steel pistons.

Additional information:
• Billet aluminum caliper material
• Black anodized or nickel plated finish
• Four-piston calipers
• Various rotor thickness and piston diameters available
• Calipers include Wilwood logo
