| 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.

Important Fitment Note:
