Description

Wilwood Narrow DynaPro radial mount race brake kits equip your UTV for high performance.

Motorsports-proven, stress-flow forged aluminum Narrow Dynapro radial mount (NDPR) front and rear calipers provide superior strength to reduce deflection under extreme use. Users will experience better pedal feel, increased brake torque, and longer pad life. Stainless steel pistons are equipped with high-temperature seals to protect brake fluid from heat and dirt.

Along with the calipers, these Wilwood race-spec kits designed for popular Side x Side machines include larger diameter steel rotors mounted to lightweight aluminum hats to reduce piston knockback. The 11.25 in. (285mm) steel rotors improve thermal capacity and are black E-coated. The calipers are Type III hard anodize finished and fitted with Wilwood's BP-28 pads.
