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.

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. Additional features and benefits: * Fully built Super Finish 3rd members--all new parts--no used housings or internal components * 29-spline pinion spline is 7 percent larger in diameter than the 27-spline for increased strength * Available in 4.88 and 5.29 ratios for 4-cylinder, V6, and high-pinion applications * Gear teeth are cut using Gleason CNC hobbing machines and cutters * No break-in period * Non-directional surface that increases lubricant retention on the gear surface, reducing lubrication requirements * Dust shield pre-installed onto flange * High-pinion sets also include a high-pinion oil slinger * V6 units feature larger OEM-style V6 gear sets with a longer pinion gear * Trail-Safe pinon seal and nut included * Flange is quadruple drilled with popular Pickup/4Runner and Tacoma patterns: -- 66mm x 66mm x 11mm (Tacoma) -- 60mm x 60mm x 10mm (Pickup/4Runner and TG heavy-duty driveline) -- 60mm x 68.3mm x 10mm -- 61.5mm x 70mm x 10mm Notes: * Requires ring and pinion setup kit to complete the installation into your existing differential housing * For Toyota 8 in. solid axles only.

RevMax's billet modified high-pressure pumps have been upgraded and modified to be able to produce over 325 psi with proper tuning. However, you would need a RevMax 68RFE valve body to be able to achieve more than 175 psi because of factory restrictions. All 68RFE pumps have been reworked with new valving and springs, and have passed multiple vacuum and pressure tests to ensure proper operation and reliability for many years. Select the RevMax modified high-pressure billet pump designed for your transmission. Note: Even though RevMax's pump can achieve extremely high pressure, it does not mean that they recommend more than 225 psi in the 68RFE transmissions.
