What is it: Ballistic Fabrication Rockwell Flat Bottom Radius Arm/Coil Mounts
Why it is cool: These laser-cut brackets make installing a radius arm-style suspension system on a Rockwell axle much simpler. Sold in pairs, these kits come ready to weld for a clean and simple mounting solution. These mounts are ideal for Ford Super Duty and early Bronco applications.
Stock 2-ton Rockwell Facts
Centersection: Double reduction-style. The upper ring-and-pinion gearset drives an intermediate gear that, in turn, drives the big, gnarly bull gear. The differential or locker is located inside the carrier on each side of the bull gear. Upper ring-and-pinion: 22 teeth on ring gear, 9 teeth on pinion = 2.44:1 Lower bull gear and intermediate gear: 33 teeth on bull gear, 12 teeth on intermediate gear = 2.75:1 Final gear ratio: 6.72:1 (combination of 2.44 ring-and-pinion and 2.75 lower gear)
Axleshaft: 1.62-inch, 16-spline
Differential: Open four-spider gear design
Bolt pattern: 6-on-8 3/4
Dimensions: Wheel mounting surface, flange-to-flange.
Front axle: 79 1/2 inches.
Rear axle, single wheel configuration: 69 1/4 inches.
Rear axle, dual wheel configuration: 79 1/2 inches.
What is it: Grizzly Locker
Why it is cool: This mechanical locker works with 16-spline axleshafts and features strong 8620 internal parts along with a patented internal design that reduces common failures associated with other Rockwell lockers. Targeted at the working man's budget, the Grizzly locker is the least expensive locker available for the Rockwell 2.5-ton.

What is it: Eaton's Detroit Locker
Why it is cool:
Eaton offers the legendary Detroit locker for the 2.5-ton Rockwell axle in several configurations depending on which specific model axle you have. Models offered include 16-, 24-, 34-, 39-, and 46-spline counts; however, every Detroit Locker delivers 100-percent drive torque to both axles when power is applied. The design allows the tire on the inside of a corner to differentiate when making turns.

What is it: ARB's Rockwell Selectable Air Locker
Why it is cool: At the push of a button, you can lock up both axles for ultimate traction on demand. When not engaged, the locker becomes an open differential-perfect for street-driven machines.
