Ultra-Light UL and ULHP straight vane rotors provide high value performance and rugged durability for a wide range of competition, high performance, and sport driving applications. Don't confuse these rotors with bargain priced off-brand named parts. Wilwood's modern manufacturing capability, combined with large scale economies, make it possible to offer this level of quality and performance at such an affordable price. Every Wilwood rotor is cast from premium grade, long grain carbon iron. This material exhibits long wear, high thermal stability, and excellent resistance to distortion in high heat. Modern foundry and machining techniques hold close tolerances on face and vane thickness.

Combining the correct face thickness with a 30 or 32 vane casting provides superior heat management and long service life with low rotating and unsprung weight. The straight vane design also makes it possible to use the same rotor on left or right hand mounting positions. UL series rotors are production machined and will provide excellent service for many applications. ULHP series rotors provide the additional performance and smoother operation of precision machined faces with less than .001" variation in flatness, parallelism, and run-out.
