The Currie 70 is simply the strongest high-pinion crate axle available, designed handle extreme off-road use and performance V8 horsepower without breaking a sweat. If you're building a serious rock crawler to take on extreme terrain, with a no back down attitude, the competition-proven Currie 70 is the axle of choice
The Currie 70 high-pinion crate 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-join.
When purchased on the Web, a master cylinder and booster upgrade kit are included to assure optimum performance of the Currie 70's larger brake system.
Built to the legendary Currie Standard with exclusive 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 extremely high torque loads are applied | |
 |
Currie's competition-grade 10.5-inch 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 9.4 in. Dana® 60 gear (right) | |
 |
Massive custom 35-spline pinion shaft (right), provides increased strength and reliability over the standard 29-spline unit (left) | |
 |
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 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 | |
 |
Massive forged 1-ton inner knuckles (right) are designed to stand up to the severe punishment of larger tires without flinching | |
 |
Upper control arm mounts feature rebuildable Johnny Joints® for maximum suspension articulation with unsurpassed durability | |
 |
Super tough Currie nodular iron front cover protects expensive internals, adds structural support to the housing's face flange and locates the driver’s side upper control arm mount | |
 |
13-inch diameter RAM 1500 (6-lug) or F-250 (8-lug) vented rotors (pictured) provide the brake torque required to stop your JL, without the cost or availability limitations of exotic brakes | |
 |
Large dual piston RAM 1500 (6-lug) or F-250 (8-lug) calipers (pictured) complete the Currie 70's brake package. With broad aftermarket support, replacement pads are always easy to find | |
 |
Upgraded JK brake master cylinder and booster (included with web orders) are volume matched to the larger calipers for optimum brake performance | |
 |
Lower control arm mounts are one-piece construction with integrated skid plates to help fend off bracket seeking rocks | |
 |
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
Wheel and Tire Size: Requires 17-inch or larger wheels for proper clearance of the brake calipers. Maximum recommended tire size is 40-inches
Overall Width: Axle width is 70-inches (+4.6 inches over stock) between wheel mounting surfaces. Additional width improves turning angle with 37-inch and larger tires
Steering Stabilizer: Ram assist brackets are not compatible with and exclude the use of conventional steering stabilizers
