JK 8-Lug Locking Hub & Slotted Brakes

Upgrade your Dana 30 or Dana 44 front axle with one of these TeraFlex JK: Dana 30/44 Front Axle 8-Lug Locking Hub Conversion Kits. Increasing the distance between the inner and outer wheel bearings dramatically reduces bearing load. The bearings ride on a forged 4140 chromoly spindle that uses readily available bearings and seals. The 8x6.5" wheel bolt pattern significantly increases wheel-to-flange strength and durability over a 5-lug bolt pattern. The SlimLock Hub Kit features forged 4340 chromoly 35-spline stub shafts. Its high-surface area engagement makes them extremely durable. High-speed front driveline failures are eliminated by disengaging the hubs for highway use or flat towing. The proprietary TeraFlex hub design seals the OEM wheel speed sensors from mud, rocks, and other trail hazards ensuring constant data transmission to maintain all ABS and ESP functions.
