JK 1 Ton Sterling ABS Kit for Jeep Wrangler (1999-2004 Super Duty) 52 Tooth
Swap a 1999-2004 Super Duty Sterling rear axle under a Jeep Wrangler JK and the very first thing the Jeep does is complain: no wheel-speed signal, ABS and traction-control codes, and eventually limp mode. This kit is the fix — a sensor mount that locates the JK's factory wheel-speed sensor on the Sterling housing plus a matched 52-tooth tone ring for the computer to read. Components are CNC machined steel, zinc plated against corrosion, and engineered from 3D scan files of the axle for accurate sensor spacing. It's the finishing piece of a 1-ton rear swap for JK owners whose factory tone rings count 52 teeth.
Features
- Locates the factory JK wheel-speed sensor on a 1999-2004 Super Duty Sterling axle
- Matched 52-tooth tone ring feeds the JK computer correct wheel-speed data
- Clears ABS and traction-control fault codes and the limp mode they trigger
- CNC machined steel, engineered using 3D scan files for accurate sensor spacing
- Zinc plated for corrosion resistance and clean sensor feedback
- Complete set — no piecing together brackets and rings from different sources
- Made in the USA
Count the teeth on your JK's original front tone ring before ordering — JKs came with either 52 or 60 teeth, and this is the 52-tooth version; the 60-tooth kit for the same axle covers the other case. Pulling your Sterling from a 2005-or-newer truck instead? Use the 2005+ Super Duty 52-tooth kit. If you only need the ring, the 52-tooth Sterling tone ring sells separately, and more swap hardware lives in our axle reinforcements collection.
JK 1 Ton Sterling ABS Kit for Jeep Wrangler (1999-2004 Super Duty) 52 Tooth FAQs
How do I know if I need the 52-tooth or 60-tooth kit?
Match your JK's factory ABS hardware. Jeep used both 52- and 60-tooth tone rings on the JK, so pull a front wheel and count the teeth on your original front tone ring before ordering. This listing is the 52-tooth version; a 60-tooth kit is available for the same 1999-2004 Super Duty axle if your count comes up 60.
What problem does this kit actually solve?
A bare Sterling axle has no provision for the JK's wheel-speed sensor, so after the swap the computer sees no signal, sets ABS and traction-control codes, and can drop the Jeep into limp mode. This kit mounts the factory sensor on the Sterling housing over a matched 52-tooth ring so the computer reads correct data again.
Do I still need a tuner after installing it?
Possibly — but for a different job. This kit restores the ABS wheel-speed signal; a tuner is what recalibrates the computer for the new gear ratio and tire size that usually come with a 1-ton swap. Most builds end up using both to get everything reading correctly.
