Description
Built for extreme off-road performance, oversized tires, and demanding heavy-duty applications, the Currie 80 Low-Pinion Full-Float Rear Axle Assembly delivers exceptional strength for Jeep Gladiator JT builds that push beyond factory axle capabilities.
Featuring a massive 11.25-inch Dana 80 low-pinion ring gear, 37-spline pinion, and 40-spline full-floating 4340 chromoly axle shafts, the Currie 80 is engineered to handle the demands of 40-inch and larger tires. Its heavy-duty construction makes it an ideal upgrade for serious rock crawlers, heavily equipped overland rigs, and custom Gladiator builds.
Available in 70-inch or 72.5-inch widths, with fully bracketed or non-bracketed housing options, the Currie 80 provides the flexibility needed for both lifted Gladiators and custom suspension configurations.
