Matched S3M Drive Belt Set 348mm for 1/10 - Arrowmax AM-910030  [AM-910030]

AM Medius S3M 348mm Drive Belts Summary

The Arrowmax AM-910030 AM Medius Belt S3M 348MM Front + Rear (2) supplies a matched pair of S3M profile belts cut to 348mm for front and rear belt paths on 1/10 on-road and touring machines. Use this set where S3M tooth engagement and identical belt lengths are required for reliable timing.

Fitting suggestions: thread each belt along the chassis belt path and over the correct pulleys, keep belts untwisted, and set tension according to your chassis manual to prevent slipping or extra bearing load. Small tension tweaks during test runs help dial in smooth operation.

Performance role: replacing aged or loose belts with correctly sized S3M belts restores tooth contact consistency and can reduce drivetrain backlash, supporting repeatable throttle response and consistent steering on smooth track surfaces.

For builders and racers with belt-driven 1/10 cars, the AM-910030 kit provides two matched S3M 348mm belts to maintain drivetrain timing; confirm pulley profile and routing before installation.
