Official Release/Features:

We are excited to announce our brand new pulley system, the Victory Series HD. This 8-rib pulley kit is heavy duty with 33% more grip. Like wide tires…it’s just cool! Unique in the market, it features a heavy duty tensioner, extra bracketing and is engineered for 500+ horsepower LS street engines.

Compact Design opens up the engine compartment freeing up more room for other things. Also solves the problem of interference between classic car crossmembers and the factory AC compressor.

Complete Kit with all the standard equipment listed below means a perfect fit and an end to the junkyard jitterbug and mail-order mamba. Spend time with your family, not your parts man.

Easy Installation makes it perfect for do-it-yourselfers. Save that money for even more hotrod parts or let your mechanic install it while you finalize your Hot Rod Power Tour plans.

Fits all Gen III and Gen IV LS style engines including LS1, LS2, LS3, LS6, LS7, LSX, L92, L99, LQ4, LQ9, LY6, L76, Vortec truck engines and more. Now is a great opportunity to experience the affordable to outrageous power and aftermarket tuning options available for these modern powerplants.

Fits the most popular throttle bodies including LS1, LS2, LS3 and cable driven in addition to high performance aftermarket brands so you can use the one you have or, if you want, upgrade later.
