Race-ready pulley upgrade from XRAY 345990

The XRAY 345990 Aluminum Side Belt Pulley 30T is a CNC-crafted upgrade aimed at improving drivetrain response on 1/10 scale touring cars. Built from Swiss 7075 T6 aluminum, it uses targeted lightening to reduce mass while keeping structural strength.

Top features of the 30T unit

  • Material: Swiss 7075 T6 aluminum for a proven strength-to-weight profile.
  • Design: CNC-machined geometry with a hardcoat surface for longer service life.
  • Performance: Lowers rotating inertia to enhance throttle and corner exits.
  • Pre-assembled: Delivered assembled so you can swap it straight in during a pit session.

Ideal for racers and club drivers alike, this pulley balances durability with lightweight design to keep drivetrain losses to a minimum.
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.

Does this pulley require special belts?

No special belts are required if your chassis uses a standard 30T side belt. Use the belt type recommended by your chassis manufacturer for best results.

Will it change gear ratios or speed?

Replacing like-for-like with a 30T pulley keeps gear ratios the same. The main benefit is reduced rotating mass, not a change in final drive ratio.

How should I maintain the pulley?

Check for belt edge wear and keep the pulley clean of grit. Re-tighten mounting hardware after a few runs to ensure nothing works loose under load.
