Our brass bushings eliminate caliper twisting caused by the rubber guide pin bushings. Precision machined brass guide bushings, and Military grade retaining clips allow your calipers to squeeze evenly on both sides of the brake rotor, resulting in much longer pad life, and a more consistent brake pedal feel. We’ve extended the lengthof the guides to make room for a heavy-duty rubber dust cap. Thiscap is designed to help protectthe guide pin lubricant from dust and debris and will extend interval of guide pin lubrication.

Guide pins require periodic lubrication.

Included:(4) Brass Guide Bushings, (4) Snap Rings,(4) Dust Caps. One set is required per axle.
