JK 1 Ton Sterling ABS Kit (1999 - 2004 Superduty) 52 Tooth

The JK 1 Ton Sterling ABS Kit is the finishing piece for a heavy-duty rear axle swap on the Jeep Wrangler JK. When you swap in a Ford Sterling rear axle from a 1999-2004 Super Duty, the JK's ABS module no longer sees the wheel-speed data it expects. This kit mounts the factory-style sensor to the Sterling housing and pairs it with a matched 52-tooth tone ring so the computer reads correct data and stays out of limp mode.

Key Features

• ABS sensor mount that locates the JK wheel-speed sensor on a Ford Sterling rear axle
• Matched 52-tooth tone ring so the ABS/traction-control system reads the correct wheel speed
• Eliminates ABS and traction-control fault codes and the resulting limp-mode after a 1-ton swap
• Steel construction sized for the Sterling axle from a 1999-2004 Super Duty
• Sold as a set so you don't have to source the sensor bracket and tone ring separately

Fitment & Compatibility

Designed for the Jeep Wrangler JK (2007-2018) running a 1-ton rear axle swap to a Ford Sterling axle pulled from a 1999-2004 Super Duty. Tone rings come in two tooth counts to match the JK's factory ABS: order the 52-tooth version if your JK uses a 52-tooth ring, or choose the 60-tooth kit if yours is 60-tooth. Count the teeth on your original front tone ring if you are unsure.

Frequently Asked Questions

Which JK does this ABS kit fit?
It is built for the 2007-2018 Jeep Wrangler JK when swapping to a Ford Sterling rear axle from a 1999-2004 Super Duty.

How do I know whether I need the 52-tooth or 60-tooth version?
Match your JK's factory tone-ring tooth count. JKs use either a 52- or 60-tooth ring; count the teeth on your original front tone ring and order to match. The 60-tooth kit is also available for the 1999-2004 Super Duty axle.

What problem does it solve?
Without correct tone-ring and sensor data, a 1-ton rear swap throws ABS and traction-control codes and can drop the Jeep into limp mode. This kit restores the correct wheel-speed signal to the JK's computer.

Do I still need a tuner?
This kit handles the ABS side. A tuner is a separate item used to recalibrate gear ratio and tire size after your swap. If you only need the tone ring, the 52-tooth Sterling tone ring is sold on its own.
