TeraFlex SKU: FNNT-3043100


Available Now!

Eliminate the weak link in your rear axle with this TeraFlex JK: Rear Axle 8-Lug Full-Float Conversion Kit. Oversized and heavier wheel/tire combos, highspeed impacts, and low range twisting and binding take a toll on JK Wrangler/Unlimited rear axle shafts and wheel bearing assemblies - even with upgraded 35-spline axle shaft conversions. All this stress can cause axle shafts to bend. The twin-bearing full-float design spreads vehicle weight evenly across the forged 4140 chromoly spindles removing vehicle weight from the axle shaft. The case-hardened 4340 chromoly shafts transfer torque to the wheels without the added stress of carrying the vehicle weight. The spindle accepts readily available industry standard bearings and seals. All factory sensors are maintained and protected from the elements. Retains OEM park brakes, calipers and pads. This kit is ideal for overland expedition style driving.
