Product Details

The Gates 37025P DriveAlign Alternator Decoupler Pulley is a precision-engineered overrunning alternator decoupler (OAD) designed as a direct OE replacement for the accessory belt drive system. Built to Gates' exacting standards, this pulley restores proper alternator function and eliminates common belt drive noise complaints.

How It Works:

Unlike a standard solid pulley, the Gates DriveAlign Alternator Decoupler Pulley allows the alternator to free-wheel or overrun each time the engine decelerates. This decoupling action absorbs torsional vibration from the crankshaft and isolates it from the alternator and belt, significantly reducing stress on accessory drive components.

Key Features:

  • OE-exact replacement — engineered to the same specifications as the original factory pulley
  • Overrunning decoupler design — allows the alternator to free-wheel on engine deceleration, reducing belt slap and wear
  • Vibration isolation — dampens torsional vibration within the accessory belt drive system
  • Improved belt and component life — reduces load on the serpentine belt, tensioner, and idler pulleys
  • Smoother engine performance — chosen by OEMs to reduce noise, vibration, and harshness (NVH)
  • Patented Gates design — unmatched by other aftermarket suppliers
  • Part of the Gates DriveAlign line, which includes overrunning alternator decoupler pulleys and one-way clutches (note: these two types are not interchangeable)

The Gates 37025P is a quality replacement that helps restore OE-level performance to the charging and accessory drive system. Proper installation tools are recommended — consult Gates' application guide for the correct removal and installation tool for this pulley.

Absolute best price on the web, very fast. Definitely ordering Autoplicity in the near future....

Bought Motive Brake Bleeding Kit (international) . Best Pricing all around.<br>Ordered on Tuesday , received via UPS Ground (cheap shipping) on Thursday Noon.<br>Excellent Packing.<br>Super Fast Shipping.<br>Very Statisfied with my on-line order.<br>Highly Recommended.

Excellent prices + great customer service = people I want to do business with... period.

Awesome price! Shipping could be faster, but it was fast enough. Will deff buy again.

Good customer service.Very friendly persons in service dept as well. Will shop here again.

This is the first time I've ordered from this site, but things look good from what I can tell so far. They had the parts I was looking for (including a fairly specialized racing part) for a price slightly lower than other places I had looked, and my order shipped the next business day. At the time I wrote this, they were also offering $5 back on my order for writing a review. ;-)

very good low price, had a slight issue but customer service was amazing,. i would recommend AutoPlicity to anyone because of that, good prices, good customer service,. (meaning trust worthy) why not :). A+++ Service will buy from again!
