About this part

Product Details

Wilwood is a well-known name in performance braking, and they make components that hold up. This caliper is a direct replacement for the GM Metric D154 style, which you'll find on many 1978 and later GM vehicles. It's also a popular choice for budget-friendly disc brake conversions and in spec racing series where reliability and cost are key.

This caliper is cast iron, meaning it's a solid, well-built piece that's ready for the road or the track. It features a 2.75-inch piston and is designed for a 1.00-inch thick rotor. Keep in mind that when you install these, you'll want to use hardened Wilwood slide pins, which are sold separately as kit number 230-0619. This kit gives you enough pins for two calipers.
