Product Details

Part Number: 7PK1283
Brand: K-Tuned

The K-Tuned 7PK1283 Replacement Belt is a direct replacement serpentine belt designed for specific K-Tuned K-Series pulley configurations. Manufactured to K-Tuned's specifications, this belt provides the correct length and OEM-style rib configuration needed to maintain proper engagement and tension throughout the accessory drive system. K-Tuned describes its replacement belts as being designed for increased strength and durability compared with simply sourcing an unknown generic belt.

Works With:
K-Tuned Adjustable EP3 Pulley Kit
  • KTD-KPE-K20
  • KPB-K20-500
K-Tuned Side Mount Pulley Kit (No PS/AC) 
  • KTD-SM2-K24
The 7PK1283 is specifically listed for the K-Tuned Adjustable EP3 Pulley Kit for K20 engines, including KTD-KPE-K20 and KPB-K20-500. K-Tuned also specifies this belt for its Side Mount Pulley Kit when using a K24 crank pulley with no power steering or A/C. This makes it a convenient replacement for an existing installation and an excellent spare belt for performance, racing, or K-Series swap applications.

  • Suitable for applicable Honda/Acura K-Series engine and swap applications
  • Ideal as a replacement for a worn, cracked, stretched, or damaged accessory belt
  • Excellent spare belt for street, race, and track vehicles

Always verify the installed pulley kit and crank pulley configuration before ordering.

I have a K24a2 with an ep3 idler pulley, an ATI crank pulley, with a deleted power steering and AC. Long story short, if you have this setup, you need this belt haha. Works perfect. No complaints.
