Spicer Drivetrain Products front axle shafts feature an increased U-joint size that provides 25 percent higher yield strength than original U-joints. They offer unparalleled strength and longer life—the outer stub is re-engineered for added strength; improved snap ring retention reduces shock load failures; and material has been removed from the body and added to the yoke ears (to equalize deflection through the yoke and reduce bearing cap spinning). The axles are made from durable steel, with a micro-alloy improving their strength and a statistically controlled heat treatment ensuring proper hardness.

Trail-Gear Rock Assault front axle housings give you clearance to go where you want and the muscle to do it! Their strength comes from heavy-duty, press-formed, 1/4 in. plate steel center sections; 1/2 in. plate steel differential mounting surfaces; 5/16 in. thick 1020 DOM axle tubes; and forged 1035 steel knuckle balls. Trail-Gear's knuckle balls are stronger than stock, so there are no worries of them becoming closed or bent. And, the thicker differential mounting surface ensures that the studs cannot pull out, even under heavy loads. Trail-Gear's design—offset tubes and shaved center section—provides you with added clearance to climb the high country. Plus, since housings are precision-aligned with computer imaging, you can rest assured they're 100 percent straight and true. You have a choice of bare tubes, or with spring perches installed—or 3-link ready with a panhard bracket included. You're equipped to attack any terrain with Trail-Gear Rock Assault front axle housings.

Unplugged Performance limited slip differentials provide a direct drop-in replacement for the stock Tesla Model 3 and Model Y open differentials. These LSDs improve the efficient distribution of power between wheels without using the brakes and stability control software. They help put more power to the ground without slowing the vehicle unnecessarily in conditions where one or more wheels lose traction, such as high G-force cornering, off-roading, and driving in inclement conditions like snow and ice. Tested and validated on the Pikes Peak Race Car with testing by Randy Pobst, Unplugged Performance limited slip differentials redistribute torque automatically to the wheel with the most traction! More product features and notes: * Gear-based design ensures smooth and silent operation without maintenance * Maximizes traction and reduces stability control interventions * Designed for performance driving—essentially no benefit for a daily driver or commuter use

Trail-Gear assembled Super Finish third members are made from tool-grade 8620 steel and heat-treated for maximum strength and wear resistance. They include all new parts and are ready to drop into your axle with top-quality Super Finish 29-spline ring and pinion gears, and your choice of locker. The ring and pinion gears are treated with the REM Isotropic Super Finishing (ISF) process, which removes the microscopic peaks in the material and creates a surface on the ring and pinion gears with a roughness of less than 10 µin Ra. This means that there is less friction between the gears, reducing wear by 95 percent, and allowing the gears and bearings to run cooler and last longer. Select the ideal kit for your application.
