Product Details

Part Number: HYB-BUN-01-A1
Brand: Hybrid Racing
Color: Black

Simplify your K-Series accessory drive with the Hybrid Racing HYB-BUN-01-A1 Idler Bracket, Pulley & Belt Combo. Designed for K20 and K24 applications where the factory hydraulic power steering pump has been removed, this complete package replaces the power steering pump with a properly positioned idler pulley while retaining the OEM automatic belt tensioner and alternator.

HYB-BUN-01-A1 is specifically configured for engines equipped with a 5.8-inch (147mm) crank pulley and includes the appropriate 50-inch serpentine belt. The system is compatible with a wide range of popular K-Series engines, including K20A, K20A2, K20A3, K20Z1, K20Z3, K20Z4, K24A1, K24A2, K24A4, and K24A8 applications.

Unlike accessory-delete setups that rely on moving the alternator to manually establish belt tension, Hybrid Racing's design keeps the factory automatic tensioning system in place. This helps maintain the serpentine belt within the intended tension range, reducing the risk of belt slip, belt walking, premature accessory wear, or charging-system problems. The revised pulley geometry also provides more than 1.5 inches of additional hood clearance compared with the factory power steering pulley.
