Caliper GM D52 2.38in Piston 1.00 Rotor

The Caliper GM D52 2.38in Piston 1.00 Rotor by WILWOOD delivers the stopping power and precision needed for high-performance braking upgrades on GM platforms. Built for enthusiasts and professional mechanics who demand reliable deceleration during spirited driving, track days, or heavy-duty towing scenarios, this brake caliper represents a proven solution for vehicles requiring superior heat dissipation and modulation. WILWOOD's reputation for engineering excellence makes this component an ideal choice for anyone upgrading from OEM braking systems.

The 2.38-inch piston design generates substantial clamping force while maintaining responsive brake feel, essential for consistent performance across varying driving conditions. The 1.00-inch rotor compatibility ensures optimal pad-to-rotor contact geometry, reducing brake fade during extended use and improving heat transfer away from the friction surface. WILWOOD calipers are engineered with precision-machined aluminum bodies and stainless steel pistons that resist corrosion and maintain consistent bore tolerances, critical factors that directly impact braking feel and durability over thousands of brake cycles.

This caliper is ideal for GM-platform applications including street-modified trucks, performance cars, and restoration projects where factory braking inadequately handles upgraded power or weight modifications. Technicians installing this caliper should verify suspension geometry and ensure proper brake line routing to maximize pad life and prevent premature wear. The lightweight construction—4.5 pounds—contributes to reduced unsprung weight, improving ride quality and handling response while maintaining the structural rigidity required for consistent emergency braking.
