1/10 On-Road S3M Front and Rear Belts 348mm - Arrowmax AM-910030  [AM-910030]

AM Medius S3M 348mm Belt Set Overview

This Arrowmax AM-910030 AM Medius Belt S3M 348MM Front + Rear (2) pair provides matched S3M profile belts cut to 348mm for front and rear runs in belt-driven 1/10 on-road and touring cars. Use these when your chassis specifies S3M tooth engagement and matched belt lengths for consistent drivetrain timing.

Installation tips: follow your chassis routing and loop each belt over the correct pulleys, avoid twisting the belt, and set slack to the chassis maker's recommended tension to prevent skipping and reduce wear. Small incremental tension changes help find the smoothest operation.

Tuning notes: renewing worn belts with correctly sized S3M belts restores precise tooth engagement, which can reduce drivetrain lash and help maintain repeatable throttle and steering response on carpet, asphalt, or other smooth race surfaces common to 1/10 scale on-road cars.

For racers and hobbyists maintaining belt-driven chassis, the AM-910030 set supplies two matched S3M 348mm belts to replace aged or stretched belts; confirm your pulley profile and path length before fitting.
