The Nissan GT-R's VR38DETT is a great platform for adding horsepower. Agency Power has had great success with Nissan performance parts and has developed yet another product to increase the performance of the VR38DETT engine. Agency Power now has this 2-piece light weight pulley kit available, consisting of an underdrive and lightweight crank pulley along with an overdrive alternator pulley. The pulley is underdriven, which allows for faster engine revving and its weight savings gains the power from reduced rotational weight. The overdrive alternator pulley is designed to have no effect on your vehicles electrical system. The Made in the USA, CNC machined pulleys are manufactured out of aircraft grade, 6061 aluminum. The billet aluminum is machined on our lathes and mills to precise tolerances making it one of the best VR38DETT pulley kits available on the market. The crank pulley features a steel sleeve to prevent any wear that a raw aluminum pulley would have on the crankshaft. Each crank pulley has a key way for perfect fit and features lightweight machined pockets. Each pulley kit includes a new belt for a direct and hassle free installation.
