Detailed Description

This serpentine belt is identified by part number 8K1264AP and is built for vehicles that use an 8-rib accessory drive layout. It cross-references common OE and aftermarket numbers, including Gates K081264 and Mopar 53041138AE, for the same application. For Ram 2500 and Ram 3500 trucks, as well as Dodge Ram 2500 and Dodge Ram 3500 models, this belt supports the accessory drive system on listed W/A.C. configurations.

Compatible With 2003-2010 Dodge Ram 2500, N/A; 2003-2010 Dodge Ram 3500, N/A; 2011-2012 Ram 2500, N/A; and 2011-2012 Ram 3500, N/A. Search terms such as Ram 2500 serpentine belt 8K1264AP, Dodge Ram 3500 accessory drive belt, and 2011-2012 Ram truck V-ribbed belt replacement align with this fitment.

What It Helps Address

  • Squealing or chirping from a worn accessory drive belt
  • Cracking, glazing, or rib wear on the existing serpentine belt
  • Loss of belt tension caused by age-related belt stretch
  • Accessory drive noise on Ram and Dodge Ram truck applications
  • Routine maintenance replacement for high-mileage belt service

Installation Notes and Tips

Verify pulley count, rib count, and belt routing before installation. Confirm the vehicle is listed with the correct W/A.C. configuration and compare the old belt length and profile to part number 8K1264AP before final fitment. Inspect tensioner and idler pulleys at the same time, since worn components can shorten belt life.

Quality Assurance

Roadmax positions this standard V-ribbed belt as a value-focused replacement option for drivers who need a quality accessory drive belt for routine service. The EPDM construction and reinforced cord design support consistent fitment for the specified Ram and Dodge Ram truck applications.
