Performance Drive Belt Tensioner Kit for Chevrolet Suburban 2500 (2000-2002) 6.0L

Heavy-Duty Serpentine Drive Belt and Tensioner Kit for 2000-2002 Chevrolet Suburban 2500 (GMT800)

What it Does: The Performance Drive Belt Tensioner Kit replaces worn factory accessory drive components on the 2000-2002 Chevrolet Suburban 2500 to eliminate belt slip, restore alternating charging stability, and maintain reliable cooling under heavy towing loads.

The Stock Chevrolet Suburban 2500 Accessory Drive Weakness

High-mileage GMT800 platforms powered by the Vortec 6000 LQ4 frequently suffer from torsional damping loss in the factory tensioner spring mechanism. Constant thermal cycling within the engine bay causes internal damping grease desiccation, resulting in tensioner arm oscillation and severe pulley bearing play. On 130-amp charging systems, this degradation causes belt slippage, parasitic drag, edge shredding, and intermittent loss of alternator output or water pump circulation under heavy payload demands.

The Engineering Solution

This comprehensive service kit restores proper drive-belt geometry using a reinforced mechanical spring tensioner, precision-ground idler pulley, and heavy-duty EPDM multi-rib serpentine belt. The high-load sealed steel bearings resist radial wear and heat degradation, maintaining uniform belt tracking and consistent dampening pressure across all front-end accessory drive components.

What's Included

• 1 Serpentine Belt (Part #6PK2360)

Frequently Asked Questions & Fitment Warnings

Does this fit the GMT800 Suburban 2500?

Yes, this is a direct fit for the 2000-2002 Chevrolet Suburban 2500 equipped with the Vortec 6000 LQ4 engine. Does not fit models equipped with the 105 Amp alternator or 8.1L Vortec 8100 engine options.

How do I confirm whether my Suburban has the 130-amp alternator?

Verify your vehicle build sheet or glove-box RPO sticker for code KG8 (130A) rather than K68 (105A) prior to belt installation.
