HPI Racing HPI RS4
The HPI Racing RS4 40T Spool Set (HPI114436) is a direct-fit differential replacement designed for HPI RS4 series radio control cars. A spool replaces the standard differential unit with a solid, locked axle arrangement, meaning both rear wheels are driven at an equal, fixed rate with no differential action. This suits drivers who want a simpler, more durable drivetrain for straight-line or oval-style running where independent wheel speed isn't needed.
Key Features
- 40-tooth spool design locks both driven wheels to rotate at the same speed, eliminating differential slip
- Direct replacement for the differential unit in HPI RS4 series RC cars
- Reduces drivetrain complexity and the number of moving parts compared to a standard diff
- Suited to oval, drag, or straight-line RC driving styles where a locked rear axle is an advantage
- Manufactured by HPI Racing to fit the RS4 platform without modification
