Upgrade Classic RX Drivetrains with XRAY 345101

For classic RX series models, the XRAY 345101 Rear Solid Axle Set provides a sensible performance upgrade without compromising strength. Crafted from HUDY Spring Steel, the axle achieves a roughly 25% weight reduction compared to the standard #345110 part, lowering rotational inertia for snappier response.

Machined for Smooth Rotation

The axle is hand-ground to deliver a dependable running surface, while heat treatment and black coating improve resistance to wear. A 48T rear composite lightweight axle pulley is included to integrate neatly with your existing drivetrain components.

Main Advantages

  • Material: HUDY Spring Steel for a balance of stiffness and toughness.
  • Reduced Rotational Mass: Around 25% lighter than part #345110 for quicker revving.
  • Longevity: Heat treated and black coated for better wear characteristics.
  • Precision: Hand-ground finish for reliable, low-friction operation.
  • Compatibility: Made to suit older RX series assemblies.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Can I use the XRAY 345101 with modern RX components?

It is tailored for older RX series mounting and geometry. Some modern components may require adapters or minor modifications, so compare dimensions before fitting.

Does the axle need bedding in before racing?

A short running-in session on the bench or a few slow laps helps seat parts and ensures the hand-ground surface beds correctly with your bearings and pulley.

Is the 48T pulley compatible with standard gearing?

The supplied 48T composite pulley matches typical rear layouts on older RX cars, but check your existing gear mesh and clearances to confirm smooth engagement.

How often should I inspect the axle for wear?

Inspect the axle after heavy sessions or every few meetings. Look for scoring, coating wear, and pulley integrity, and replace if you detect excessive wear.
