120-8062-LRD - Product Description

Billet Narrow Superlite 4

The Superlite caliper series has set the standard for many years in short track, late model, modified and open wheel competition. It has also enjoyed prominence in a variety of road-race, off-road, rally and sport driving applications. Starting at 4.40 pounds, the Forged Billet Narrow Superlite (FNSLR) is innovation to this series from Wilwood. New and adaptive technologies have been applied providing substantial improvements in strength, fluid volume displacement, and overall performance. FNSL4R calipers are the the only Superlite series calipers with piston dust boots, primarily for export mandates.

The FSL body design is a highly efficient product of computer generated solid modeling and stress analysis technology. Each caliper features closed end bridges with a radial transition to the piston body 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. Center bridge bolts replace cotter pins to provide additional support and allow quick access with positive brake pad retention. Clamping force, structural deflection, and volume displacement tests have proven the superior strength and efficiency of the FSL. On-track testing has proven driver satisfaction. The bottom line is better stopping power with less pedal travel.

Additional Notes

The superior strength of this innovative new caliper is combined with proven performance features from other Wilwood designs. Each caliper is equipped with Wilwood's replaceable SRS stainless steel bridge plates. SRS plates eliminate the bridge wear caused by pad gouging and extend the service life of the caliper body. The spring-loading action of the SRS plates also eliminates pad rattle and dampens the vibration harmonics that contribute to squeal under braking. Other standard Wilwood features include high-temperature, square faced o-ring seals for positive sealing, controlled piston retraction, and long service life in high heat conditions. Stainless steel pistons are used to resist corrosion and retard heat transfer from the pads. Fluid tubes are vibration dampened to resist stress fractures and reduce damage caused by track debris. Two-piece bleed screw assemblies provide long, reliable service life and are easily replaced if necessary.

Forged Billet Superlite calipers are a direct replacement for all Wilwood Superlite and similar competitive brand calipers with 3.50" centered mounting tabs. Calipers are available in the popular 1.75", 1.62”, 1.38", 1.25” and 1.12” piston sizes for .81", 1.10" and 1.25" rotor widths. FSL calipers use the same 7420 type bridge bolt brake pad used in all Superlite 6 piston calipers. The full range of PolyMatrix pad compounds is available to match brake response and heat range to any application.
