Product Details

Part Number: HYB-BUN-01-A2
Brand: Hybrid Racing
Color: Black

Simplify your K-Series accessory drive with the Hybrid Racing HYB-BUN-01-A2 Idler Bracket, Pulley & Belt Combo. Designed for Honda and Acura K-Series engines with the factory hydraulic power steering pump removed, this kit replaces the power steering pump with a properly positioned idler pulley while retaining the OEM automatic belt tensioner and alternator.

The HYB-BUN-01-A2 configuration is specifically designed for engines equipped with a 6.25-inch (159mm) crank pulley. It pairs Hybrid Racing's common K-Series HYB-IDB-01-02 idler bracket with the HYB-BLT-00-03 51.2-inch (7PK1300/512K7) serpentine belt for applications deleting both power steering and A/C.

Unlike accessory-delete setups that rely on manually repositioning the alternator to establish belt tension, Hybrid Racing's design retains Honda's factory automatic tensioning system. This helps keep the belt within the proper operating tension range, reducing the risk of belt slip, belt walking, charging issues, and excessive accessory wear. The compact idler arrangement also provides more than 1.5 inches of additional hood clearance compared with the stock power steering pulley.

  • Applicable mounting hardware
  • Hybrid Racing HYB-BLT-00-03 51.2" 7-rib serpentine belt
For the HYB-IDB-01-02 system with power steering and A/C deleted, belt selection is based on crank pulley diameter:
  • HYB-BUN-01-A1: 5.8" crank pulley / 50.0" belt
  • HYB-BUN-01-A2: 6.25" crank pulley / 51.2" belt
  • HYB-BUN-01-A3: 6.50" crank pulley / 52.0" belt
Important Fitment Note:
  • HYB-BUN-01-A2 is specifically configured for a 6.25-inch (159mm) crank pulley with both hydraulic power steering and A/C deleted.
  • Crank pulley size should be measured at the outside diameter before ordering.
  • If you plan to retain A/C, this bundle's supplied 51.2-inch belt is not the correct length; Hybrid Racing specifies a longer belt for power-steering-delete applications retaining air conditioning.
