GM D154 Metric Caliper 120-13900

Though a multi-piston body this new caliper is a single-piston design.

These ultra-strong forged calipers are fully detail machined and stress-analysis tested. They provide the lightest overall weight with the highest resistance to deflection – even when compared to much heavier and bulky cast aluminum parts, bar none.

The calipers feature an anodized finish, with low-heat conduction stainless steel pistons and positive retraction bore seals. Fluid inlets have been relocated to the center of the piston bore to eliminate any possible interference with the slide pins. Bleed ports at both ends accommodate left, right, front, or rear position mounting.

Available with 2.00in or 2.50in pistons, Wilwood’s new high-end caliper costs only $112.20
