Durable X20 '23 Differential Case from Serpent 402045

The Serpent 402045 aluminum differential housing replaces the X20 '23 plastic unit with a tougher, more accurate option. It is built to reduce internal movement and protect the drivetrain during hard running.

Solid Construction for Reduced Drivetrain Play

Forged from robust aluminum and CNC finished, the housing maintains precise alignment under load. The improved fit minimises energy loss in the drivetrain and supports repeatable setup adjustments.

Simple Fitment Procedure

This housing is a direct replacement for the X20 '23 model, so you can reuse your existing differential internals and mounting hardware. The swap keeps installation time to a minimum, letting you focus on setup and testing.

Specifications

  • Material: Aluminum
  • Compatibility: Serpent X20 '23
  • Includes: Left and Right differential housings

For club racers and serious hobbyists seeking a tougher drivetrain foundation, the Serpent 402045 is a reliable upgrade for the X20 '23.

Does the 402045 require new bearings or hardware?

No new bearings are normally required. The housing is machined to accept the original X20 '23 bearings and hardware, but inspect bearings during the install and replace if worn.

Will aluminium housings affect differential wear?

Aluminium can reduce flex-related wear by keeping components aligned, which often extends the life of gears and bearings compared with a flexing plastic case.

Is this part suitable for endurance events?

Yes. The added durability and stable alignment make the 402045 a good choice for longer races where component longevity matters.

Can I paint or anodise this housing?

Anodising should be done before installation if desired, but ensure tolerances are maintained. Painting is possible but may affect bearing seating if applied to mating surfaces.
