This is a complete parts master kit with everything needed to do a professional primary reduction install. The master kit is for the do-it-yourselfer and includes ALL the recommended extra parts. Includes our stiffer stage 1 or stage 2 clutch springs(depending on reduction size), front output shaft seal, gasket maker and centrifugal clutch puller.

*This is not for the DCT/Auto machines. For an auto machine, please add the Install Kit located under the parts section. They do not require the clutch springs that are included in the Master Kit. 

*If purchasing the master kit for a reduction you already have, please note the reduction size in the order notes so we can give you the correct springs needed.
