ARB Air Locker — Dana 35 (27-Spline, 3.31 & Down)

A stock Dana 35 with an open diff loses drive the instant one wheel unloads. The ARB Air Locker converts it into a driver-selectable, fully locked axle on demand: switch it on for 100% traction on the trail, switch it off for smooth, predictable open-diff driving on the road.

This carrier fits standard 27-spline Dana 35 axles running 3.31 and numerically lower gears — the factory setup across the Ford Explorer, Ford Ranger, Mazda Navajo and many Jeep Cherokee, Grand Cherokee and Wrangler models. On-demand engagement gives you a locked axle only when you need it, with no everyday penalty.

  • Selectable, air-operated 100% differential lock
  • Forged internals for the 27-spline Dana 35 axle
  • Matched to 3.31 & numerically lower ratios
  • Instant engagement from an ARB air source

Trade-off: needs a compressed-air supply and professional installation. Confirm your spline count and gear ratio before ordering.
