Description
Modified or replacement rear axle differentials available to increase the towing and carrying capacity of your RAM 1500 Ute! View the available options below…
WHY GET A JMACX RAM DIFF HOUSING?
- AXLE LOAD INCREASE: The rear axle load capacity increases from factory standard 1770 Kg to 2500 Kg, increasing carrying capacity by 730 Kg!
- DESIGN: Full float hub and larger stronger wheel bearings to suit the increased load rating. This is a major factor as to why JMACX differentials are so sought after.
- RERATING: While some competitors may rerate axles on paper only, JMACX stands by the fact that rerating should not occur without an upgrade. JMACX provides the upgraded parts required to achieve carrying capacity.
- AFFORDABILITY: The modified and replacement options are more affordable when compared to the significant cost of an OEM replacement.

All Diff Housing have an NON Optional Core Exchange: $ 2000.00
The JMACX modified housing works on an undamaged core exchange basis. The customer agrees to relinquish their factory diff housing and is supplied a JMACX modified diff from stock. All Diff options require a deposit of $2000 for the core exchange. This deposit will be refundable depending on the condition of the differential when assessed by the JMACX HQ Differential Team. If the differential is deemed in sound rebuildable condition, a full deposit will be refunded. If additional parts are required only partial deposit will be refunded based on the cost of the repair parts. If the differential is damaged beyond repairable use then no deposit will be refunded. Diff sales without a core exchange (no diff available for exchange) can be only discussed with JMACX HQ.

Frequently Asked Questions:
Can I just rerate my axles by applying the Queensland 10% upgrade?
No. Under state legislation the rerating of axles is not compliant. You can’t exceed the manufacturer’s axle load rating by applying the Queensland 10% upgrade.
Why doesn’t JMACX provide an axle rating greater than 2500kg?
To exceed 2500kg in your GVM will exceed the chassis strength of the car, working against the limitations of the vehicle.
Why do I need load rated wheels?
Due to the increased carrying capacity and increased weight, load rated wheels are required. If your rims are load rated, note that some are only bored part of the way at the dimension of the hole, and must be bored right through to suit (approx. 78.1mm).
