Serpent 500406 SRX4 Rear Diff Inserts Precision Pack  [SER500406]

SRX4 Differential Upgrade with Serpent 500406

If you run an SRX4, the Serpent 500406 rear differential inserts provide a straightforward upgrade to the diff internals. Engineered to match SRX4 geometry, these inserts aim to extend service intervals and support steadier handling through a range of track conditions. The kit includes six accurately produced inserts made for consistent duty.

Performance and build quality

The inserts seat cleanly inside the SRX4 differential housing to reduce uneven wear and improve vehicle control. Built from robust materials, they are suitable for regular club use and for drivers who want predictable behaviour from the rear end.

Installation pointers

Fitting is simple: press each insert into place and confirm correct alignment before reassembling the diff. Avoid forcing parts and inspect fitment prior to use. Carry out routine checks after a few practice sessions to detect wear early.
