Product Details

The Gates 37044P DriveAlign Overrunning Alternator Decoupler Pulley (ADP) is a direct-fit, OE-grade replacement pulley engineered to restore proper alternator function in your accessory belt drive system. As an original equipment manufacturer, Gates designed this pulley to allow the alternator to free-wheel or overrun during engine deceleration, isolating vibrations that would otherwise transfer through the serpentine belt drive system.

Key Features:

  • OE Exact Replacement: Engineered to match original equipment specifications for a seamless, no-modification installation
  • Overrunning Decoupler Technology: Allows the alternator to free-wheel during deceleration, reducing stress on belts and drive components
  • Vibration Isolation: Absorbs accessory belt drive system vibrations for quieter, smoother engine operation
  • NVH Reduction: Selected by OEM manufacturers to minimize noise, vibration, and harshness
  • Extended Component Life: Enables lower belt tension, reducing wear on belts, bearings, and related drive components
  • Improved Fuel Economy: Optimized decoupler action reduces parasitic drag during engine deceleration
  • Patented Design: Gates-exclusive construction unmatched by other aftermarket suppliers

Cross-Reference Part Numbers: ACDelco 37044P | Carquest 37044P | Volkswagen OEM 06B903119B

Important Installation Note: Vehicles designed to use an Alternator Decoupler Pulley (ADP) must never be fitted with a solid pulley or one-way clutch pulley. These pulley types are not interchangeable — installing the incorrect style can cause damage to accessory drive components.

good price

I accidently ordered the wrong part and was given credit that allowed me to order the right part. Great Price and good service!

Autoplicity was plenty cheaper than competitors for the springs I needed. I was shopping around and left the website after beginning a transaction and they sent me a coupon for 25% off shipping if I would return and purchase from them, which was cool. Unfortunately the coupon code didn't change the price and I didn't receive 25% off, but it was still cheaper than others.

Great just what I wanted.

The headlights look great the price was fair but the lights don't operate correctly.

shipped fast, cant wait to put it on the jeep, would buy from here in the future.

I am not happy with my back rack, it arrived all scratched up and I would like a replacement one, I will ship this one back but I am not going to pay for shipping. Please contact me on how u want to handle this. Tim Sullivan
