Performance Drive Belt Tensioner Kit for Ram 1500 (2014-2020) 3.6L

Heavy-Duty Drive Belt Tensioner Kit for 2014-2020 Ram 1500 (DS/DT)

What it Does: The Performance Drive Belt Tensioner Kit replaces the factory accessory drive wear items on the 2014-2020 Ram 1500 to prevent belt slip, restore proper accessory drive tension, and eliminate rotational bearing noise.

The Stock Ram 1500 Belt Drive Weakness

The factory accessory drive on the 3.6L Pentastar V6 relies on cast spring tensioners and composite idler pulleys subject to continuous thermal cycling and rotational fatigue. Over time, the OEM tensioner internal dampening spring loses calibrated torsion, leading to belt whip and accessory decoupling. Simultaneously, factory idler pulley radial bearings dry out and develop axial play, causing belt misalignment, rib glazing, squealing, and premature belt snapping under load.

The Engineering Solution

This direct-fit kit restores dynamic dampening and accessory alignment across the front engine drive. Featuring a heavy-duty cast tensioner body with a calibrated internal steel spring, it maintains uniform linear load on the belt across all RPM ranges. Matched with dual precision-machined idler pulleys equipped with premium high-temperature sealed ball bearings, this kit mitigates parasitic drag and bearing seize. The included 6PK1670 multi-rib EPDM serpentine belt resists heat checking, rib cracking, and elongation under heavy alternator and AC compressor loads.

What's Included

• 1 Serpentine Belt (6PK1670)

Frequently Asked Questions & Fitment Warnings

Does this fit the DS / DT 1500?

Yes, this is a direct fit for the 2014-2020 Ram 1500 equipped with the 3.6L Pentastar V6 engine. This kit does not fit 5.7L HEMI V8 or 3.0L EcoDiesel V6 models.

What belt length is included in this kit?

This kit includes a 6PK1670 serpentine belt (6-rib, 1670mm effective length); verify your engine routing and application requirements before ordering.

The Ram Work-Ready Standard

When hauling payloads or towing, consistent mechanical dampening of the serpentine drive is essential to preserve cooling system performance, hydraulic charging, and alternator reliability under high electrical demands.
