Dexter K71-773-01 Right-Hand Caliper Assembly Kit, DB35 Disc Brake, 3.7K-7K Axle, Zinc

The Dexter K71-773-01 is a right-hand (curb-side) caliper assembly kit built for Dexter DB35 trailer disc brakes on axles rated from 3.7K through 7K pounds. It is designed as a complete caliper assembly for this side of the axle, giving trailer owners a direct way to replace a worn, seized, or corroded caliper without sourcing individual internal components separately.

The kit carries a zinc finish, which helps the housing resist the corrosion that trailer brake components are constantly exposed to in wet boat-ramp and roadway environments -- a key consideration for boat trailers and other trailers that see regular submersion or salt exposure.

Because this is a right-hand specific assembly, it is not interchangeable with a left-hand caliper kit; the two sides use separate part numbers and must be matched to the correct wheel position when ordering. This kit is intended for Dexter DB35 disc brake systems within the 3.7K to 7K axle capacity range.

Frequently Asked Questions

What side does the Dexter K71-773-01 caliper kit fit? The K71-773-01 is a right-hand (curb-side) caliper assembly kit only. It is not interchangeable with a left-hand caliper, which uses a separate Dexter part number, so confirm which side of the axle needs replacement before ordering.
