Unmatched Strength and Durability

For performance enthusiasts and street pros looking to upgrade their GM 6L80 transmission, the 104680-45 clutch kit is an essential component. At its core, this kit features a one-piece 300M steel forging, which is heat-treated and shot-peened to provide maximum durability and resistance to stress fractures. Unlike the stock OE design that relies on a weak, welded connection, this high-performance clutch component is custom-forged to withstand extreme conditions.

One of the most common failures in performance vehicles with 6L80 transmissions is the shearing of the rear splines and the breakage of the 4-5-6 clutch hub. This upgraded shaft eliminates those weaknesses, ensuring that your vehicle maintains peak performance under demanding conditions. Whether you’re launching at the track or pushing your vehicle on the street, this clutch kit is built to handle the stress.

Optimized Oil Flow for Maximum Performance

Heat is the enemy of any clutch system, especially in high-RPM applications. The 4-5-6 clutch releases in 1st, 2nd, and 3rd gears, making constant oil flow crucial for performance and longevity. This clutch kit features an innovative hub design that doubles oil flow to the clutch pack, significantly reducing heat buildup and preventing premature clutch wear.

By optimizing oil circulation, this kit enhances power transfer and ensures smoother, more reliable shifts. Whether you’re running your vehicle hard on the street or the track, this advanced design helps maintain clutch integrity under extreme conditions. If you’re serious about performance, this is the clutch kit you need to improve reliability and efficiency.
