Transmission Specialties' 4L80E 300M extended spline input shafts have all the latest and greatest updates that make them the strongest on the market. Feed hole changes have been made to make the shaft stronger. The splines that go into the OD planet have been lengthened and the undercut shoulder which has a very small inside diameter, has been removed. TSI also used a hobb to cut this spline—as compared to others who single point cut, which makes for a weaker spline and is considered to be the number one spot of failure for other aftermarket billet shafts. Crafted from premium-grade 300M material, the 4L80E input shafts are engineered to be more durable than traditional shafts, ensuring reliable and consistent performance, even under extreme loads. The extended design offers increased spline engagement into the OD planet, reducing the chance of shaft failure and improving overall strength. Whether you're racing, towing, or just looking to improve your vehicle's performance, make an upgrade to your transmission with high-quality TSI components.
