Wilwood D52 Caliper Upgrade
Wilwood’s new D52 calipers are a direct bolt-on replacement for all ’68-and-later GM muscle cars, passenger vehicles, and light-duty trucks that were originally equipped with the big single-piston D52 pad calipers. The calipers are built to mount in the stock location, with stock dimension rotors, using regular OE type or aftermarket compound replacement pads, and fitment anywhere the OE calipers were used.
The new D52 calipers provide a lightweight, high-strength, extreme-duty alternative for customized street machines and all competition vehicles that still require OE mounting. The forged billet aluminum bodies provide a substantial weight savings (without the rust and corrosion) over the original cast-iron calipers. The two-piston design improves pad loading and clamping efficiency over the single-piston design, with an increase in overall piston clamping area to improve stopping power. Stainless steel pistons with high-temperature bore seals minimize heat transfer and provide maximum durability in the most extreme circumstances. A smaller bore rear model is available to help maintain proper front-to-rear bias on vehicles that have been converted to four-wheel discs. Optional color finishes are available to complement wheel, tire, and rotor upgrades on all types of customized machines.
