HPI 87006 Urethane Belt S3M 507 UG 4mm Front Sprint Sprint 2 Drift Sprint 2 Sport Sprint 2 Flux

Keep your HPI Sprint 2 running smooth with this genuine HPI 87006 front urethane drive belt. This S3M 507 UG belt measures 4mm wide (169 teeth) and is the factory front belt for the HPI Sprint, Sprint 2 Drift, Sprint 2 Sport, and Sprint 2 Flux 4WD chassis.

The urethane construction resists stretching under hard acceleration and cornering loads, keeping power transfer consistent between the front and center pulleys. Over time, belts wear from friction, debris, and heat — a slipping or noisy front belt is a common sign it's time to swap in a fresh one.

This is a genuine HPI Racing replacement part, made to the same spec as the belt that came with your kit, so fitment and tooth engagement are correct out of the box.

Includes: 1 x S3M 507 UG 4mm front drive belt.

Compatible with: HPI Sprint, Sprint 2 Drift, Sprint 2 Sport, Sprint 2 Flux.
