Kit is complete with an drilled chromoly steel front sprocket, black case hardened steel rear sprocket, DID 525VM2 gold plated X'ring sealed chain cut to length and a rivet style master link. Stock gearing is 17/45. Surface treated by Anticorrosive treatment, to make the sprockets more attractive in appearance and antirust.The sprockets and chain are matched exactly by Formula Parameter Analysis, which ensure the excllent capability.Above 20,000 kilometers guaranteed for normal driving. The Stage I kit lowers your final drive ratio about 10% through the sprocket sizes. So, that means, you will increase your rpm's by about 10%, reach your shift points much faster, accelerate much harder, and reach your top spped much quicker. Because the Stage I doesn't increase your rpm's so much that you will reach the revlimiter in top gear, your top speed won't be effected. And, in fact, when the rider weights 190+, the kit can actually increase your terminal velocity by allowing your engine to rev higher in top gear, creating more hp, and help overcome the natural rolling and wind resistances.
This is the best all-around performance seup in gearing ratio.

Pair of JUN cam sprockets for the Toyota 2JZ-=GGTE and 1JZ-GTE engines. Arguably the best offering on the market. Will give more accurate cam timing.The Stage II kit is approx. an 18% change and offers about the maximum amount of gearing change while using the stock chain length. This kit will move all your shift points up by about 2 gears. Unless you weight 200+, you can expect to see a compromise of 5-10% (10-15mph)in top speed.Complete Stage I, Stage II, Street Stunt, and Pro Stunt Drive Kits and 520 Conversion Kits are also available for these models. The Stage I sprocket set is designed to give you the maximum acceleration and increased thrust, WHITHOUT sacrificing top speed, AND allowing you to retain your stock length chain! And, you don't even have to break the chain or remove it to install this sprocket kit. (We will provide you with step by step install tips on how to accomplish this.)
