OE Part Numbers: 4854089AB, 04854089AB, 04854089A, 38163, 89245
Durable Metal & Plastic Construction: Constructed from high-strength metal and engineering-grade plastic. The metal core provides robust structural integrity to withstand high belt tension, while the durable plastic pulley ensures smooth, low-noise operation and excellent fatigue resistance under harsh under-hood conditions
Optimized V-Ribbed Pulley Design: Features a 70mm outer diameter, 25mm wide V-ribbed pulley with a smooth contact surface. The precision-engineered grooves minimize belt slippage for stable power transfer, while the 17mm precision bearing bore ensures smooth rotation, significantly extending the service life of both the belt and tensioner assembly
High-Precision Sealed Bearing: Equipped with a 17mm precision sealed bearing, pre-lubricated with double-lip dust seals. This design effectively blocks dirt, debris, and moisture intrusion, maintaining low friction and quiet operation in off-road or wet conditions, significantly enhancing long-term durability and reliability
Simplified Single-Bolt Installation: Designed with a single mounting bolt hole that aligns perfectly with OEM specifications. This simplified installation requires tightening just one bolt to secure the assembly, dramatically reducing repair time and allowing for easy access even in tight engine bay spaces
