Mark Williams Enterprises Off-Road Brake Kits Reduce Unsprung Weight, Deliver Precise Braking Control

We know Mark Williams Enterprises makes driveline parts that are used in many different racing applications but did you know that the company has a line off-road brake kits for hardcore off-road competitors? These kids are designed to reduce weight, provide precise braking control, and also to stand up to the harsh environment that they’ll be subjected to.

The massive benefit of these kits starts with the weight reduction. How about taking 160lbs of unsprung weight off of your rig?! Think about the positive effects of that on performance in terms of acceleration, suspension operation, handling, etc. It jus goes on and on.

If you are an off road enthusiasts and want to upgrade or are in the middle of a build. This is your kit!

Here’s the full story from Mark Williams on their Off-Road brake kits –

Off-Road Brake Kits


These new kits will clean up the extreme overkill of the OEM brake kit and save 160 pounds per vehicle. Designed for reducing weight (rotating and unsprung suspension) while providing precise brake control.

The MW quick change caliper design is stronger than common 6061 aluminum billet versions and utilize a rigid mount, opposing piston arrangement. Each piston retracts independently and has zero drag when released. The internal porting reduces the possibility of line damage from foreign objects. Ports with 3/8” hex bleeder screws are on both ends for easy bleeding. – No right and left hand calipers! Most importantly, the MW caliper features massive 7/16” oversize fasteners that reduce caliper spread at high operating pressures plus a 5/16” diameter bridge bolt for added strength. The pad features a single center bolt / bushing retaining system for easy lining replacement.

The disc is 3/8” thick with a giant 14.0” diameter, which increases the braking torque compared to smaller rotor designs. The disc material is abrasive resistant, heat-treated high-carbon steel that is double-disc ground to be flat and parallel. The problems of warped or cupped discs from heat build up are removed and rotor life is extended with our exclusive Slot-Drive™ attachment system. The brake systems are designed to be compact and move the disc inboard to eliminate interference with wheels.

The aluminum adapters are drilled to accept 5/8” studs in dual bolt circles for the original 05+ F350 hub metric pattern and 6-1/2″ x 8-bolt. The caliper mounting brackets are 5/16” thick 7075 aluminum. Each brake kit includes all fasteners required for assembly.
