High-Performance 104680-45-P Billet Shaft for Maximum Strength
The 104680-45-P billet shaft is crafted from one-piece 300M steel forging, ensuring maximum strength and durability. Unlike weaker OE designs, this heat-treated and shot-peened shaft resists stress fractures and provides superior torque handling. Designed for use without an OE damper, this machined component enhances transmission performance in high-power applications. Its improved construction prevents premature wear and enhances road reliability, making it an ideal upgrade for performance vehicles.
Optimized Oil Flow and Clutch Durability
One of the standout features of this billet shaft input is its ability to double oil flow to the clutch pack. This enhanced circulation significantly reduces heat buildup, improving resistance to thermal stress and extending clutch life. The intermediate shaft is specifically designed to work with 45-tooth clutch plates, ensuring a secure fit and optimal engagement. By eliminating the weak, welded OE connection, this upgraded shaft prevents common transmission shaft failures, such as rear spline shearing and hub breakage.
Engineered for High-Performance Transmissions
Built for GM 6L80 transmissions, the 104680-45-P billet shaft input replaces the stock two-piece assembly with a stronger, more durable design. This intermediate shaft is precision-machined to enhance transmission durability while supporting high-RPM shifts and extreme power loads. Whether on the street or track, this shaft ensures smoother operation, increased torque capacity, and long-lasting performance in even the most demanding driving conditions.
Frequently Asked Questions
How does the 104680-45-P billet shaft improve transmission durability?
This billet shaft is made from one-piece 300M steel forging, which is heat-treated and shot-peened for maximum strength and resistance to wear, preventing common failures like spline shearing and hub breakage.
Why is improved oil flow important for clutch performance?
The 104680-45-P billet shaft input doubles oil flow to the clutch pack, reducing heat buildup and extending clutch durability, especially during high-RPM shifts in performance vehicles.
Can this billet shaft be used in both street and track applications?
Yes, this machined intermediate shaft is designed for high-performance GM 6L80 transmissions, offering increased torque capacity and durability, making it ideal for both street driving and competitive racing.
What makes this shaft better than the OE input shaft?
Unlike the stock two-piece welded shaft, this billet shaft input is a one-piece forged design, eliminating weak points and providing superior strength, torque resistance, and reliability under extreme conditions.
Do I need additional components to install this intermediate shaft?
This transmission shaft is designed for use with 45-tooth clutch plates, which must be purchased separately to ensure proper fitment and optimal clutch performance.
