• Zero Crankshaft Runoff: The crankcase stabilizer locks down your crank in perfect alignment, preventing unwanted lateral movement and protecting bearings, seals, and variator components from premature wear.

• Reinforced CVT Housing: The Ultimate CVT Cover isn’t just a protective shell – it’s a structural reinforcement. Precision-machined with upgraded solid front and rear points, it adds rigidity to the transmission side of your engine case and helps distribute stress more evenly.

• Swingarm Rigidity Perfected: When used together, these components transform your stock GY6 case into a race-ready setup that handles torque, road shock, and aggressive acceleration without flex or wobble.

• Bolt-On Brilliance: Engineered for direct fitment on all standard GY6 150cc long-case engines, installation is straightforward with no fabrication required.

Whether you’re building a high-horsepower scooter, trike, or GY6-powered race scoot, this is the go-to upgrade to stabilize your drivetrain and eliminate crankshaft walk for good.
