Aluminium rear centre upper for GTX flat chassis

The XRAY 354022 aluminium rear centre upper mount is an aftermarket replacement tailored to GTX 2026 flat-chassis configurations. Crafted from Swiss 7075 T6 aluminium, the component reinforces the rear centre mount to help retain accurate gear alignment under increased load.

Its precision machining limits flex at the gearbox interface and improves heat transfer from the transmission housing. These factors work together to support more consistent 2-speed engagement by reducing drivetrain deflection during aggressive throttle and braking inputs seen in club and national racing.

In terms of setup, this mount is a direct way to adjust rear driveline stiffness without modifying suspension geometry. Increasing mount stiffness can reduce shifting irregularities caused by chassis twist, while softer options preserve compliance. Treat the part as one element of a wider setup strategy.

Specifications

  • Item: Aluminium center 2-speed upper mount, rear
  • Material: Swiss 7075 T6 aluminium
  • Model Number: 354022

If you want firmer drivetrain behaviour on a GTX 2026 flat chassis, this machined aluminium upper mount is a sensible upgrade. Verify fitment and re-evaluate shift performance under real running conditions after installation.

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.
No standard cutting is expected. The CNC-machined mount is made for accurate alignment on compatible GTX 2026 flat chassis mounts, but always inspect hole alignment and clearance before final assembly.
Yes. By stiffening the gearbox pick-up, the mount can reduce chassis-induced misalignment that causes inconsistent shifts. Expect a firmer driveline feel; balance this with suspension setup to avoid introducing harshness.
Use the hardware specified for your chassis and gearbox, and torque bolts evenly to the manufacturer recommendations. Over-tightening can distort parts and alter gear mesh.
Start with static gearbox checks, then run progressive track sessions while monitoring shift points. Compare before and after behaviour at similar track temperatures and power settings to confirm gains.
