Performance Drive Belt Tensioner Kit for Chevrolet Tahoe (2000-2002) 4.8L 5.3L

Heavy-Duty Serpentine Belt Drive Kit for 2000-2002 Chevrolet Tahoe (GMT800)

What it Does: The Performance Drive Belt Tensioner Kit restores optimal accessory drive tension and eliminates belt slip on the 2000-2002 Chevrolet Tahoe to maintain reliable alternator, water pump, and power steering operation under heavy load.

The Stock Chevrolet Tahoe Accessory Drive Weakness

Factory belt drive components on the GMT800 platform suffer from severe thermal fatigue over prolonged operating cycles. The stock mechanical tensioner's internal torsional spring loses damping rate, leading to dynamic belt flutter, chirp, and premature pulley bearing seizure. Additionally, the OEM polymer idler pulley degrades from localized engine bay heat soak, resulting in axial bearing play, belt misalignment, and sudden drive belt derailment—especially under high accessory loads common with the 130-amp charging system.

The Engineering Solution

This direct replacement drive kit resolves harmonic instability and belt stretch on GM Vortec 4800 (LR4) and Vortec 5300 (LM7) V8 powerplants. The assembly incorporates a high-durability steel idler pulley equipped with sealed, low-friction precision ball bearings to withstand high radial loads. Paired with a heavy-duty cast aluminum tensioner mechanism engineered to maintain consistent dynamic load, and an EPDM-formulated 6-rib serpentine belt (6PK2360) resistant to rib cracking and oil degradation, this kit ensures complete drive stability and zero slip under full throttle or heavy towing conditions.

What's Included

• 1 Serpentine Belt (6PK2360)

Frequently Asked Questions & Fitment Warnings

Does this fit the GMT800 Tahoe?

Yes, this is a direct fit for the 2000-2002 Chevrolet Tahoe equipped with the LR4 4.8L or LM7 5.3L V8 engine, specifically models equipped with the 130-amp alternator option; it does not fit models with the standard 105-amp or high-output 145-amp alternator setups.

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

Check the factory RPO code sticker in your glove box for code KG8 (130-amp alternator) or verify the stamped amperage rating on your alternator case before installation.
