Unity Mfg

The clean, minimalist design deliberately recalls the iconic first-generation Performance Machine brake rotors from the 1980s – true classics that are sadly no longer in production. Simple, no-frills, exactly how a brake rotor should be: functional, reliable, and extremely durable. Available in the proven diameters 10 inch (254 mm) and 11½ inch (292 mm). Precision-drilled mounting holes for 5/16" or 3/8" bolts – compatible with many custom and vintage setups. Manufactured from high-grade 420 stainless steel – the material of choice for maximum resistance to wear, warping, and corrosion, even under tough conditions and extended periods of inactivity. Center bore: Ø 56 mm. Perfect for purists, custom builders, and anyone who appreciates authentic old-school looks combined with solid, up-to-date engineering.

These kits contain three wrenches and a clothespin. The wrench sets consist of three 7/16” wrenches or two 1/2” and one 7/16”. They are thin enough to fit those thin nuts, but strong enough to tighten everything securely. The box ends on the opposite side are 5/8“ and, for example, sized to fit the Super E Floatbowl plug. With the tapered end you can pry off the pushrod retaining clips. Made of stainless steel in Ohio/USA.

These UNITY adapters fit a 3/8-inch torque wrench and allow to properly tighten the cylinder and cylinder head nuts on a pre-EVO HD. The kit includes three different sizes: 7/16“, 9/16”, and 5/8".
