The Extreme 60 high pinion front crate axle is simply the strongest 60 series axle that we offer, designed for severe off-road use with up to 40-inch tires and V8 conversion horsepower. The Extreme 60 front axle is built to the legendary Currie Standard and features: our high pinion nodular iron radius bottom center section with additional reinforcement in critical areas, large 3.5-inch axle tubes, massive 13.25-inch rotors with late-model JK calipers and Currie 1-ton heavy duty steering components, plus much more. The Extreme 60 front axle combines unmatched strength with superior performance in a comprehensive, bolt-in, axle, steering and brake upgrade for Jeep TJ/LJ vehicles

PROP 65 WARNING:

Bolt-in front axle package for Jeep TJ Wrangler and LJ Unlimited features an Extreme 60 1-ton housing with Currie heavy duty steering components (drop pitman arm, tie rod, drag link, and trac bar kit), big 13.25" brakes with JK calipers plus much more.

 

Built to the legendary Currie Standard with exclusive features including:

Extreme 60 Axle Housing:

  • Extreme 60 high-pinion nodular iron center section is the strongest 60 series casting we offer, additional reinforcement in critical areas over the already strong Currie 60 center section
  • Highest measured ground clearance of any 60 on the market (and that’s including the integrated skid plate), guess the other guys have trouble reading a tape measure
  • Radius bottom center section with an integrated hardened steel skid plate significantly improves obstacle slide-over by presenting a smooth curve rather than the sharp edge found on other 60 housings
  • Ring gear load bolt maintains proper gear mess by eliminating deflection, dramatically increasing the torque handling capacity of the gear set
  • High volume flow-thru recirculating oil system keeps pinion bearings bathed in cool oil, reducing operating temperatures and extending bearing life
  • 3 1/2" diameter 3/8" wall axle tubes provide massive strength without the excess weight of smaller thicker tubes
  • Currie Performance 35-spline (1.5 inch) 4340 chromoly inner and outer axles for superior end to end strength
  • Warn Premium heavy duty 35-spline, 1-ton locking hubs deliver reliable operation and fuel economy
  • High quality and heavy-duty components and brackets used throughout.

Brakes:

  • Big 13.25-inch brake rotors (RAM 1500 truck) are more than 2 inches larger than the stock TJ and provide a massive brake performance upgrade without the upfront or replacement cost of exotic aftermarket rotors
  • New late model JK calipers (with pads) maintain compatibility with the stock TJ/LJ master cylinder and keep maintenance cost low by using widely available aftermarket replacement pads

Steering:

  • Currie Currectlync® 1 3/8” diameter heat-treated chromoly tie rod with 1-ton ends for unsurpassed strength and reliability
  • Currie heavy-duty 1 3/8" chromoly Johnny Joint® trac bar with relocation bracket and frame brace eliminate the failure-prone stock components 
  • The Currie drop pitman arm improves steering geometry, reducing the bump steer commonly found with lifted TJ/LJ 
  • Currie heavy-duty 1 3/8" chromoly drag link with 1-ton tie rod ends provides a serious upgrade and completes steering package

Notes

Wheel and Tire Size - Requires 17-inch or larger wheels for proper brake caliper clearance. Maximum recommended tire size is 40-inch

Wheel Bolt Pattern - Requires wheels with either 5 on 5 1/2" or 6 on 5 1/2" bolt pattern based on the option selected

Stud Size - 1/2 inch studs are used for both 5 and 6 lug options

Overall Width - The housing assembly is 64-inches wide between wheel mounting surfaces (+2.5" wider than stock TJ/LJ) to provide additional clearance and improved turning angle with large tires.

Differential Carriers - Carriers provided by Currie for the Extreme 60 are turned down to 8.300" O.D. for load bolt clearance. If a standard O.D. carrier is installed the load bolt must be backed out to prevent damage
