XRAY 355038 38T front bevel gear for XB8 in hardened HUDY steel

The XRAY 355038 38T front differential bevel gear is made from hardened HUDY steel, chosen for its toughness and dimensional accuracy. Built for the XB8 series, this bevel gear runs smoothly with lower vibration thanks to precise machining and chamfered tooth edges that assist gear meshing. The laser-engraved "38" mark makes identification fast during setup. Swapping the stock 40T to this 38T yields a 3.167 gear ratio, which helps tame acceleration on rough surfaces and improves front-end stability.

Specifications

  • Material: Hardened HUDY Steel
  • Tooth Count: 38T
  • Compatibility: XRAY XB8 Series
  • Gear Ratio: 3.167 (with 38T)

A solid choice for hobbyists who want more predictable handling and better traction on bumpy or technical tracks while retaining durable hardware.
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.

How does the 38T change handling compared to the 40T?

Reducing the tooth count to 38T lowers the final ratio to 3.167, smoothing acceleration and making the front end less twitchy on rough sections. That translates to easier steering input and improved stability under throttle.

Will this fit my XB8 without modification?

Yes, the gear is designed for the XRAY XB8 series and installs in place of the factory 40T bevel gear with no chassis alterations required.

Any tips for installation and break-in?

Check mesh and backlash during installation, run a short break-in at low loads, and inspect for even wear. Proper lubrication and a correct pinion match will extend gear life.
