You get both the front and rear heavy duty Currie axle housings (listed below) as well as a Yukon premier Air locker (with 6 yr warranty) and a high quality gear set, all setup and ready for paint and your calipers on the front and your rotors and calipers on the rear.

The RockJock III high pinion frontend assembly for the 2007 and up Jeep JK includes the complete housing featuring the 65-45-12 ductile iron housing center (highest ground clearance 60 on the market), AR400 heat treated bottom skid plate allowing the axle to slide over rocks easily, 3" x .375" wall d.o.m. steel tubes, 1 ton inner knuckles, 5/16" thick heavy steel diff cover, yoke, and all new heavy duty Currie Jeep JK suspension brackets mounted. Upper control arm brackets are equipped with Johnny Joint rod ends for maximum articulation.
Axles shafts are the Currie performance 4340 35 spline inner and outer with Spicer 1480 u-joints. Outer assemblies include 1 ton outer knuckles featuring Currie "high steer" steering arm and ball joints installed, Currie exclusive 1 ton unit bearings with 5 on 5 1/2" wheel bolt pattern and JK tone rings allowing for ABS and ESP retention, 13" vented rotors (over 1" greater diameter than stock for increased braking), zinc plated caliper brackets that allow the use of the stock JK front calipers, Currie drive flanges or premium manual locking hubs, and our heavy duty 1 3/8" o.d. 4130 chrome moly tie rod with tie rod ends.
NOTES: This unit is 68.75" wide. This unit requires the use of 17" wheels. 2012 and newer vehicles will need a computer programmer, such as the AEV ProCal Module to reset the gear ratio and tire height in the vehicle's computer.

All new heavy duty Currie Jeep JK suspension brackets are mounted and feature multiple control arm mounting holes, multiple trac bar mounting holes, and adjustable shock mounting holes.
