ROCKJOCK® 44 HIGH PINION JK RUBICON HEAVY DUTY REPLACEMENT FRONT END HOUSING WRITE-UP
Price Starts At: $1,999.95
The Currie RockJock®
high pinion 44 is an all new, heavy duty 44 made 100% by Currie
. Their casting is a heavy duty, ductile iron piece that uses the larger JK high pinion 44 gears only. These gears feature a larger ring gear than a standard 44 as well as a 29 spline Dana 60 size pinion gear. Tubes are 3" x .375" wall. All new heavy duty JK suspension brackets are mounted on this housing for an easy bolt in installation and Currie's
forged JK knuckles are installed. These are completely custom-built units that are made-to-order to each customer's specifications and application. They provide a much stronger assembly than the factory frontend in Jeep JK vehicles.
Unit is the factory 65.400" overall finished width. This housing weighs 134lbs., where a stock JK high pinion 44 front housing weighs 91lbs. Housings do not include ball joints, cover or yoke. Must use part number 44-4109JKHP solid spacer & shim kit when setting up gears.
There are multiple companies that are now making the replacement 44 housing, but Currie Enterprises®
stepped up to the plate when I spoke with them about what I was looking for. Currie Enterprises®
offered for me to come out and take a tour and also take photos of the housing during assembly. I had some upgrades like TeraFlex’s big rotor kit, and Reid Racing® Knuckles that I wanted to transfer over. Currie Enterprises®
walked me through step by step of what they would be doing to the housing and what upgrades were available. I chose to have Synergy ball joints installed, Yukon 5.13 gears, Yukon Zip Locker, and I couldn’t be happier with the way the housing turned out, the way I was treated through the whole process, and the quality of everything that was done. I can’t wait to do the rear 60 next!

My write-up does not include the install of gears, lockers or any other housing upgrades. Please seek your closest reputable gear specialist before installing your new housing!
Park Jeep on level ground and prepare for axle housing removal.
• Pull the e-brake up/engage.
• Lightly loosen front wheels lugs with 19mm Socket or 3/4 and lug key if you have locks.
• Jack the Jeep up high enough off the ground and install the jack stands.
• Once done, now remove all the loosened wheel lugs and place wheels/tires underneath frame of Jeep.
If you are intending on removing the unit bearings in the interest of upgrading your outer axle shafts and you will be using hand tools, loosen axle nut before removing brakes. Easiest way to remove it is to have someone engage foot brake while you break free the axle nut.
Remove brake rotors, calipers, and abs sensors.
• Separate abs lines from the brake lines.
• Remove rotor tabs.
• Remove the 2 caliper bolts using 21mm wrench or socket.
• When you remove calipers, use zip ties to hold out of the way to avoid damage to brake lines.
• Slide off brake rotor and put to the side.
• Behind rotors are the abs sensors. Remove with 8mm allen wrench. Once sensor is removed, unclip the abs cable and completely separate it from axle housing.
