Forged S/L Caliper 1.625 /1.25

The Wilwood Forged S/L Caliper 1.625/1.25 is a high-performance brake caliper engineered for serious vehicle modification and track-focused builds where weight reduction and stopping power are non-negotiable. Built by Wilwood, an industry leader in racing and performance brake systems, this forged aluminum caliper delivers the precision braking response that enthusiasts demand when upgrading OEM systems or building custom brake kits.

The 1.625/1.25 designation refers to the dual-piston bore configuration—1.625-inch and 1.25-inch pistons—that delivers balanced brake force and modulation across varied driving demands. Forged aluminum construction minimizes weight while maximizing rigidity, reducing unsprung mass and improving vehicle dynamics without sacrificing structural integrity under high-temperature braking cycles.

Mechanics and fabricators routinely specify this caliper for complete brake system builds on street rods, muscle cars, and performance platforms where OEM geometry or clearance limitations exist. The S/L design incorporates Wilwood's proven sliding configuration, allowing smooth caliper movement on the brake rotor while maintaining consistent pad contact and eliminating brake fade during sustained deceleration—critical for road course driving or consecutive hard stops at the drag strip.
