Race-focused builders can use the Serpent 500524 trans-case inserts to run a 4 gear laydown setup in the SRX2 MH. The inserts help keep gear trains aligned and resist deformation under heavy use on race day.
The Serpent 500524 inserts reduce gearbox flex and help the transmission hold a consistent mesh. That leads to fewer surprises on the track and steadier car behaviour during repeated high-load passes.
These inserts fit the SRX2 MH trans-case and can be installed with common workshop tools. The quick swap-in nature makes them a practical choice for racers who need a dependable transmission upgrade with little fuss.
