120-7568-RS - Product Description

Billet Superlite 4 Lug Mount

The billet SL4 caliper incorporates Wilwood's latest technology in a conventional 3.50" centered lug mount design, with weights starting at 4.94 pounds. This caliper series has been structurally designed for high clamping efficiency and low deflection in a body width compatible with all wide 5 and 5 x 5 style hubs. It is a direct replacement for all other Superlite style calipers.

The SL4 series bodies are the products of FEA solid modeling and stress analysis technology. A reinforced radial transition between the piston housing body and the solid bridge is combined with a full body length reinforcement rib to give this caliper the highest resistance to deflection and separation under load of any Superlite style caliper available. Four high strength steel bridge bolts and a fifth center bridge bolt further add to the superior clamping efficiency while providing easy access to the 7420 style pads.

All SL4 series calipers use a big differential bore four-piston design. The 1.88" / 1.75" piston sizes provide the largest effective piston clamping area of any model in the Superlite series. The differential bore pattern uses the pressure variance between the bore sizes to compensate for the natural temperature changes cross the face of the pad and the natural tendencies for the pad to "self load" on the leading edge. The split balance of the pad loading promotes even pad wear in the higher temperature applications. Standard SL4 models use one piece stainless steel pistons for their low heat transfer properties and their high resistance to corrosion.

Additional Notes

Every SL4 caliper incorporates new and adapted performance features from other Wilwood designs. Each caliper is equipped with replaceable SRS stainless steel bridge wear plates. SRS plates eliminate the bridge wear caused by pad gouging to extend the service life of the caliper. The spring-loaded action of the SRS plates eliminates pad rattle and dampens the vibration harmonics that contribute to pad squeal. The bodies are machined with recesses to protect the fluid crossover tubes and bleed screws. The fluid tubes are dampen mounted and two piece bleed screw assemblies assure reliability in harsh conditions and round out the total performance package. The full range of Wilwood brake pad compounds is available in the 7420 type pads to match the brake response and heat range of any competition application.
