This is the newest Currie Rock Jock 70 REAR Axle. This is the same axle we run in our 800HP Ultra4 racer, 640HP Terremoto JK and Bowtie TJ for over 4 years!
This is a complete Full Float, 40 spline rear axle with NO mounting brackets (except the bridge for upper control arm mounts), so it's ready for the control arm mounts of your choice so they get welded on by you in the proper location that is specific to your vehicle!
This axle is IN STOCK and ready for immediate pick up (or delivery for an extra fee).
We figured out a long time ago that new aftermarket axles custom ordered and built from scratch are the way to go! You get a hi-pinion in the rear (which keeps the rear driveshaft up out of the rocks AND allows for optimal geometry (pinion angle) and the maximum amount of droop (for crazy articulation)!
Currie uses the HUGE 10-5/8" ring gear and 35 spline pinion gear from a Dana 70 axle. Huge 3-3/4" diameter axle tubes with 40 spline CrMo axle shafts and full float hubs!
These axles are also manufactured with Currie's trademark "rotated" diff cover to prevent leaking from damage on the trail.

We now offer 3 different brake options: Oversize OE style caliper/rotors, R1 or Alcon.
These rear axles have a "centered" diff housing so the axle shaft length's are equal.
This is a "bare" (no brackets) axle, as we feel it is best to position the axle first then attach the brackets in the optimum position and location for your vehicle (allowing for bigger tires or stretched wheelbases).
The brakes will require a "banjo" style connection that may be larger than your existing brake line.
Upper Control Arm mounting brackets (RSM-1010) are sold separately and require welding to install them onto the rear axle bridge..
