JK 1 Ton Sterling ABS Kit for Jeep Wrangler (2005+ Super Duty) 52 Tooth
This kit closes out the electronics side of a Jeep Wrangler JK rear axle swap using a Sterling from a 2005-or-newer Super Duty. The later Sterling puts the sensor provision in a different spot than the 1999-2004 trucks, so this version is machined specifically for the 2005+ housing: a sensor mount that positions the JK's factory wheel-speed sensor correctly, paired with a 52-tooth tone ring the computer can read. Everything is CNC machined steel, zinc plated, and developed from 3D scans of the axle. Install it and the ABS codes, traction-control faults, and limp mode that follow a bare 1-ton swap go away.
Features
- Sensor mount machined for the 2005+ Super Duty Sterling sensor location
- 52-tooth tone ring matches JKs with 52-tooth factory ABS rings
- Restores correct wheel-speed data — no more codes or limp mode after the swap
- CNC machined steel engineered from 3D scan files
- Zinc plated for corrosion resistance and a clean sensor signal
- Sensor mount and ring arrive as one matched set
- Made in the USA
Verify your tooth count first — count the teeth on the JK's original front tone ring and order 52 or 60 to match; the 60-tooth version for the 2005+ axle covers 60-tooth Jeeps. Note that fitting the tone ring requires machining a groove in the Sterling hubs, so line up a machine shop before install day. Running a 1999-2004 donor axle instead? Choose the 1999-2004 Super Duty 52-tooth kit. The 2005+ Sterling ABS mounting plates are also available on their own, and the rest of the swap hardware is in our axle reinforcements collection.
JK 1 Ton Sterling ABS Kit for Jeep Wrangler (2005+ Super Duty) 52 Tooth FAQs
Why is there a separate kit for 2005+ axles?
Ford moved the wheel-speed sensor provision on the 2005-and-newer Super Duty Sterling, so the mount geometry differs from the 1999-2004 axle. This kit is machined for the later housing; if your donor axle came from a 1999-2004 truck, order the earlier kit instead. Both versions do the same job of restoring the JK's ABS signal.
Is any machining required to install it?
Yes — the Sterling hubs need a groove machined in them so the tone ring can seat, which is the one step most owners farm out to a machine shop. Once the hubs are cut, the ring and sensor mount install easily. Plan that machine-shop visit into your swap timeline.
How do I pick between 52 and 60 tooth?
Count the teeth on your JK's original front tone ring — the factory used both counts, and the replacement must match or the ABS will read wheel speed wrong. This is the 52-tooth kit; a 60-tooth kit for the same 2005+ Sterling axle is available if your Jeep uses 60.
