Caliper L/H Superlite Radial Mnt 1.25in Rotor

The Wilwood Caliper L/H Superlite Radial Mount 1.25in Rotor is a left-hand, four-piston aluminum brake caliper engineered for high-performance braking systems requiring precision and lightweight construction. This driver-side caliper delivers responsive braking action through a radial mounting design compatible with 1.250-inch-thick rotors and a 5.98-inch radial mount footprint. Gray anodized aluminum construction resists corrosion while minimizing unsprung weight—a critical consideration in performance and off-road applications where brake fade, heat dissipation, and stopping power directly impact safety and vehicle control.

The four-piston design provides superior clamping force distribution across the brake pad surface, improving modulation and reducing stopping distance compared to dual-piston calipers. The 14.00-inch outer diameter rotor specification indicates this caliper is optimized for larger-displacement engines or vehicles requiring robust braking capacity. Superlite aluminum construction keeps total caliper weight to 5.35 pounds, allowing builders to reduce overall vehicle mass without sacrificing brake response. The radial mount configuration offers superior alignment control and eliminates deflection issues common in floating-mount designs, ensuring consistent pad contact and extended rotor life.

This caliper is specified for vehicles requiring OEM or custom performance brake upgrades—including vintage muscle cars, track-focused builds, off-road recovery vehicles, and motorsport applications. The left-hand (driver-side) orientation ensures proper brake line routing and lever geometry. Buyers integrating a Wilwood brake caliper system must verify rotor compatibility, brake line inlet size, and pad material specifications to match their vehicle's thermal and stopping-power requirements. The radial mount pattern is critical; confirm your vehicle's mounting surface accommodates the 5.98-inch radial specification before purchase.
