Heavy-Duty Drive Belt Tensioner & Pulley Kit for 2001-2002 Chevrolet Silverado 3500 (GMT800)

What it Does: The Performance Drive Belt Tensioner Kit restores calibrated accessory belt tension and pulley alignment on the 2001-2002 Silverado 3500 to eliminate belt slip, bearing noise, and parasitic charging loss under heavy towing loads.

The Stock Chevrolet Silverado 3500 Belt Drive Fatigue

Factory belt drive components on high-mileage GMT800 trucks deteriorate rapidly under high-load cycles and harsh engine bay temperatures. The OEM internal spring mechanism in the stock tensioner loses dynamic damping force over time, leading to excessive lateral belt deflection, uneven rib wear, and compromised alternator output under high electrical demands. Furthermore, worn factory idler pulley bearings develop rotational runout, producing audible high-pitched squeal, premature belt shedding, and potential accessory drive failure on the job site.

The Engineering Solution

This comprehensive drive service kit incorporates a reinforced cast aluminum tensioner assembly (38158) fitted with an internal heavy-duty coil spring engineered to dampen harmonic vibrations and maintain exact belt tension across the entire RPM range. Paired with a heavy-duty idler pulley (38001) housing sealed high-grade steel ball bearings, this system eliminates pulley wobble and grease washout. The included heat- and crack-resistant EPDM serpentine belt (6PK2360) maximizes grip on accessory drive pulleys, ensuring reliable 130-amp alternator charging and water pump operation in high-heat conditions.

What's Included

  • 1 Serpentine Belt (Part # 6PK2360)
  • 1 Idler Pulley (Part # 38001)

Frequently Asked Questions & Fitment Warnings

Does this fit the GMT800 Silverado 3500?

Yes, this is a direct fit for the 2001-2002 Chevrolet Silverado 3500 equipped with the 6.0L LQ4 engine and factory 130 Amp alternator option. This kit does not fit models with the 105 Amp alternator or vehicles equipped with the 6.6L Duramax Diesel or 8.1L Vortec engines.

How do I verify if my truck has the 130 Amp alternator?

Inspect the service parts identification (SPID) sticker in your glove box for RPO code KG3 to verify 130-amp alternator sizing prior to installation.
