The Currie 70 high-pinion, full-floating rear crate axle is simply the strongest high-pinion rear axle available, designed for extreme off-road use with 40+ inch tires and performance V8 horsepower. If you're building a serious rock crawler to take on extreme terrain, with a no back down attitude, the competition-proven Currie70 is the axle of choice
*** NOT COMPATIBLE WITH 4-CYLINDER ETORQUE EQUIPED VEHICLES***
The Currie 70 high-pinion, full-floating rear axle for the 2018 and newer Jeep JL Wrangler, is a complete bolt-in axle assembly with all required brackets and mounts in place. The vehicles factory driveshaft will require modification or replacement to accommodate the larger 70 series housing and 1350 series u-joint
Built to the legendary Currie Standard with features including:
 |
Currie 70 high-pinion nodular iron center section is competition proven and the strongest casting we offer, with heavy main caps, ARP® main bolts and thicker walls and webbing in critical areas | |
 |
Ring gear load bolt (top left) eliminates gear deflection, to dramatically increase torque handling capacity. The load bolt typically sits .002 inch from the ring gear and only touches when the gear begins to deflect under high torque loads | |
 |
Currie's competition-grade 10.5-inch Currie 70 gears (left) are cut from super tough 9310 alloy, and then custom heat-treated to a precise hardness, creating gears that can stand up to both the high shock loads of extreme off-road use and the wear of high mileage street use. Standard Dana® 60 gear (right) | |
 |
Massive custom 35-spline pinion shaft (right), provides increased strength and reliability over the standard 29-spline unit (left) | |
 |
The Currie 70 high-pinion radius bottom center section delivers unmatched ground clearance, and improved obstacle slide-over by presenting a smooth curve rather than the sharp edge found on other 60 housings | |
 |
Replaceable AR400 hardened steel skid plate resists deformation and gouging to slide over obstacles far better than iron housings or mild steel plates | |
 |
Large diameter outer pinion bearing (right) is designed for the demands of reverse rotation/high pinion housings. Stock low pinion bearing (left) | |
 |
High volume flow-thru recirculating oil system keeps pinion bearings bathed in cool oil, reducing operating temperatures and eliminating oil starvation issues | |
 |
Large 3.5-inch diameter .375 wall axle tubes (left) are three times stronger than the stock JK Dana® 44 (right) without being overweight or sacrificing ground clearance | |
 |
Chromoly spindles and billet steel full-floating hubs carry the weight of the vehicle, eliminating the influence of side loading and impact shock on axle durability. Safety is improved as the wheel and brake remain in place and fully functional in the rare event of an axle failure | |
 |
Nearly indestructible 40-spline (1.7-inch dia.) full-floating chromoly axles are the perfect match for high horsepower, big tires, and extreme terrain | |
 |
Includes new 13.50-inch rotors with the selected bolt pattern and machined for full-float hub clearance. Calipers, backing plates, and e-brake are Rubicon direct fit, making service parts easy to find | |
 |
Currie nodular iron front cover protects expensive internals and adds structural support to the housing's face flange for increased rigidity | |
 |
Heavy duty 3/16 inch brackets feature multiple mounting options for adjusting suspension geometry to accommodate a range of vehicle lifts | |
 |
Black satin powder coat finish adds long-lasting protection against rust and corrosion to keep your Currie 70 looking its best |
Notes
ABS Sensors - Does not include ABS sensors, the factory sensors from the stock axle must be retained and installed on the Currie housing
Computer Programming - 2012 and newer vehicles require a computer programmer, such as the AEV ProCal Module to reset the gear ratio and tire height in the vehicle's computer for proper function of the vehicles stability control and transmission shift points
Brake Components - Includes new 12-inch JK rear rotors with the selected bolt pattern, rotors and backing plates are machined to clear the full-floating hub. Calipers and e-brake assembly are OE direct fit
Overall Width - Axle width is 70-inches (+4.6 inches over stock) between wheel mounting surfaces, provides increased tire clearance for large tires
Wheel and Tire Size - Requires 17-inch or larger wheels for proper brake caliper clearance. Maximum recommended tire size is 40-inches
