Serpent 401073 - S400 S411 Bearing Eccenter Service Part  [SER401073]

Keep Bearings True with Serpent 401073

The Serpent 401073 Bearing Eccenter is a small but important spare for S400 and S411 cars that helps bearings sit correctly in the hub assembly. Proper alignment reduces binding and keeps rolling resistance low, making the car easier to tune and more predictable on track.

Engineered Fit for S400/S411

This eccenter is formed to match Serpent hub tolerances so it installs cleanly without fuss. By cutting down on bearing misalignment you also lower the chance of uneven wear on adjacent parts, which helps extend overall component life.

Fitting Tips for Club Racers

Clean the hub and bearing seat before installing the eccenter, then rotate the wheel to check for free spin. Light grease and correct fastener torque will keep the assembly secure without causing binding.
