Wilwood Brackets (2) - Drag - Chevy 3.15in Bearing

If you're setting up a drag car and need to mount a caliper to a Chevy 3.15-inch bearing axle, these Wilwood rear drag brackets are what you're looking for. They're built to work with 11.44-inch diameter solid rotors, a common size for drag racing applications.

These brackets are made from a strong aluminum alloy, keeping the weight down while still being able to handle the forces involved. For mounting the caliper itself, they use steel 3/8-24 clinch nuts, which are known for holding up well under repeated use. Wilwood offers these in many common axle flange patterns, so you can usually find one that fits your specific setup without needing custom fabrication.
