The XRAY 345591-O Lightweight Aluminum 2-Speed Shaft Collar is made from high-grade 7076 T6 aluminium to reduce inertia on the 2-speed shaft. By lowering rotating mass, the collar helps sharpen throttle response and makes the car feel livelier without sacrificing strength. The bright orange finish makes it easy to identify during teardown and setup.
Replacing a stock composite collar with this aluminium option improves drivetrain efficiency and can contribute to smoother acceleration. The 7076 T6 alloy delivers a longer service life under demanding running conditions compared with many plastic alternatives.
