Frequently Asked Questions

Will this fit a standard 14-bolt rear disc conversion?

Yes. This JB6 brake caliper loaded unit is the industry standard for the rear disc brake conversion GM owners prefer. It pairs perfectly with weld-on or bolt-on brackets designed for a 7.045" mounting span.

Can I use this for both the driver and passenger sides?

Absolutely. The GM dual bleeder brake caliper features an ambidextrous Dual Bleeder Caliper design. This allows you to flip the caliper to either side while keeping a bleeder screw at the highest point for easy maintenance.

Is this a remanufactured part?

No. This is a 100% New Casting Caliper. Every component is brand new, ensuring maximum reliability for your Chevrolet 3/4 Ton 4WD Front Caliper replacement or custom axle swap.

What is the advantage of the 2-15/16" Piston?

The 2-15/16" Piston size is significantly larger than "Metric" style calipers, providing superior clamping force which is essential for heavy rigs and oversized tires.
