Jeep Wrangler JK Axle Assemblies | Fusion Pro Series Fabricated 10" Front Axle Assembly and Fusion Pro Series Fabricated 10" Rear Full Float Axle Assembly
The Fusion Pro Fabricated 10" axle combines the latest and greatest in race proven axle technology and packages it into a bolt-in axle assembly that is ready for anything from daily driving to pro level racing. The axle includes the same High Pinion Gearworks Third Member design that crossed the finish line in 1st Place at King of the Hammers in 2016 and 2020.
The basics of what you need to know when comparing this axle to alternatives: LIGHTER, STRONGER, FASTER, MORE GROUND CLEARANCE.
FABRICATED 10" HOUSING - THIS IS ONE BAD A## HOUSING!
- 3.5" x 3/8" DOM Tube
- Formed 1/4" plate center section made from high-strength, low alloy, structural steel
- 1/2" face plate made from high-strength, low alloy, structural steel, which is machined after welding to ensure a perfect fit with the third member
- LIGHTWEIGHT at approximately 70 lbs.
- Only 5/16" less ground clearance than a JK front D44 and 1/2" more than a D60
- INCLUDED JK bracket kit made from 1/4" steel, laser cut, and CNC bent
FRONT AXLE FEATURES:
GEARWORKS HIGH PINION 10" THIRD MEMBER - THE SAME CASES YOU WILL SEE UNDER UNLIMITED CLASS ULTRA4s AND TROPHY TRUCKS
HIGH PINION: Where the magic happens. Ford 9" axles were designed for rear axle low pinion applications. Running a low pinion in the front means running on the weak side of the gears. In addition, the very low pinion position creates undesirable driveline angles that can create significant issues with longer travel suspension. This GEARWORKS case uses high pinion reverse cut 10" gears, making it the strongest high pinion front differential available, while providing for optimal driveline angles.
- 10" RING AND PINION: If you're going to make custom gears, why not make them larger?! In addition to a larger ring gear, it utilizes a larger 35 spline pinion vs. the standard 28 spline.
-
LOAD BOLT: The case includes a load bolt to prevent ring gear deflection (the most common cause of gear failure under load). Under load, if the ring gear starts to deflect, it hits the load bolt, thereby preventing a potential failure.
FUSION KINGPIN OUTER ASSEMBLIES - BECAUSE FRIENDS DON'T LET FRIENDS RUN BALL JOINTS
- Fusion HD Kingpin Inner Cs, USA forged out of high-quality alloy steel
- Fusion HD Kingpin Knuckles, cast in the USA. Knuckles are designed to use a race style fully machined steering arm and secured by 6 ARP studs
- Fusion 1480 Forged Chromoly Axle Shafts, heat-treated and induction hardened, 35 spline - LIFETIME WARRANTY
- 8 x 6.5 Wheel Bolt Pattern
- JK ABS: Included is an OE quality ABS kit to ensure your vehicle works as the manufacturer intended
- BIG BRAKE KIT: A standard on Fusion axles. Massive dual piston calipers and 13.25" rotors, providing maximum stopping power for large tires and heavy rigs.
- Standard Yukon Hardcore Locking Hubs. Without a doubt, the strongest locking hubs available
FUSION 2.5 TON STEERING - NO FUSION AXLE IS COMPLETE WITHOUT INDUSTRY LEADING STEERING
- Backed by our NO BS lifetime warranty. Should you ever manage to bend the tie rod or a forging, send us a picture and we'll replace the affected part.
- Massive 1-1/4" shank heat-treated forged ends
- Anti-rotation bushings that limit tie rod roll, resulting in tighter steering, especially when used with hydro assist
- 1.75" diameter solid 7075 aluminum. 7075 is popular in off-road racing due to its "memory." If you hit the tie rod hard enough to make it flex, the bar will return to straight. The aluminum is CNC machined to exact tolerances. Just because you're not racing in King of the Hammers doesn't mean you can't run the same parts!
- Wrench flats for easy installation
- Lock washers to prevent jam nuts from loosening
- Replaceable cartridge ends should one ever wear out
REAR AXLE FEATURES:
HEAVY DUTY LOW PINION OR HIGH PINION THIRD MEMBERS
- All cases are race proven
- GEARWORKS case upgrades for those customers planning big power and big tires
- Additional benefits of GEARWORKS cases: larger carrier bearings to reduce gear deflection under load, load bolt to ensure the ring gear stays in full contact with the pinion, available high pinion version.
