Wilwood 160-16979 Drilled Steel UTV Rotor 11.25x0.25 in. Dynamic Lug 8x7.18

Vehicle Fitment

• Universal UTV Fit - Designed for UTV brake system applications using an 8 x 7.18 in. dynamic lug-mounted rotor bolt pattern and a 6.00 in. lug ID / registration diameter

Fitment Notes

• Designed specifically for UTV applications - not intended for passenger cars, trucks, or motorcycles
• Dynamic lug-mounted design - uses snap ring retention instead of a traditional fixed bolt-circle hat mount; confirm hub and caliper compatibility before ordering
• Snap Ring hardware kit (Wilwood P/N 300-12561 - Dynamic Lug Rotor Mounting and Snap Ring Kit) is required and sold separately
• Non-directional rotor - no left/right designation; can be mounted on either side
• For use with Wilwood UTV calipers only - not compatible with OEM stock calipers
• Rotor mount hole type is lug-mounted; verify complete hub and mounting hardware compatibility before installation

Features

• Solid drilled alloy steel construction engineered for UTV brake performance in low-to-moderate temperature environments
• Cross-drilled surface pattern reduces pad glaze buildup, assists in gas and heat dispersal, and lowers rotating mass compared to solid undrilled rotors
• Dynamic lug-mounted design allows the rotor to float slightly on the lugs, reducing thermal stress and distortion under repeated heating and cooling cycles
• Special alloy and proprietary manufacturing processes provide high resistance to thermal distortion with excellent friction and wear characteristics
• Black electro-coat finish applied for corrosion protection in off-road and outdoor UTV environments
• Lightweight at 4.22 lbs. - minimizes unsprung weight for improved UTV handling and suspension response
• Solid (non-vented) construction suited to the intermittent braking demands typical of UTV trail and off-road use

Product Description

The Wilwood 160-16979 is a solid drilled alloy steel brake rotor purpose-built for UTV applications. Featuring a dynamic lug-mounted design, the rotor floats slightly on the mounting lugs rather than being rigidly fixed - this reduces thermal stress and warping under the repeated heat cycles common to aggressive off-road braking. The cross-drilled surface pattern helps disperse heat and gas at the pad interface, while the black electro-coat finish provides durable corrosion protection in the muddy, wet, and dusty conditions UTVs encounter.

At just 4.22 lbs., this lightweight rotor minimizes unsprung weight without sacrificing the strength needed for UTV trail riding, desert racing, or utility work. The dynamic lug-mounted snap ring system requires Wilwood's Dynamic Lug Rotor Mounting and Snap Ring Kit (P/N 300-12561), sold separately. Verify hub lug ID (6.00 in.) and caliper compatibility with your specific UTV brake setup before ordering.
