Specs At A Glance

Good To Know

Q: Do I need extra hardware to install this bracket? A: Most installs reuse the original compressor bolts and accessory hardware, though some swap combinations may require additional spacers or fasteners. Check the bracket against your compressor and engine before bolting everything down.

Q: Can I use this with any A/C compressor? A: This bracket is intended for R4 style compressors, so other compressor families may not line up. Verify your compressor style matches before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
