Wilwood GM III Calipers represent the latest refinements in caliper design and manufacturing through solid modeling and stress simulation programs. The result is the most rigid, highest torque, lightweight aluminum caliper with weights starting at 3.36 pounds.

Wilwood GM Metric Calipers are direct replacements for 1978-Up GM D154 metric calipers. Available in lightweight aluminum starting at 2.9 pounds or all-NEW cast iron for a low-cost OE replica caliper.

Note:

• All Wilwood GM Calipers require the use of hardened Wilwood Slide Pins (Slide Pin Kit #950-230-0619 contains 4 slide pins, enough for two calipers, available separately)
• GM III Calipers require D52 Brake Pads
• GM Metric Calipers require D154 Brake Pads
