Product Details

The URO 11-28-7-557-851 is a deflection pulley designed for BMW vehicles. This pulley guides and maintains proper tension on the accessory drive belt system, ensuring optimal alignment and preventing belt slippage. The deflection pulley works in conjunction with the belt tensioner to route the serpentine belt around various engine accessories including the alternator, power steering pump, and air conditioning compressor.

Key Features:

  • Direct replacement for OEM part number 11-28-7-557-851
  • Precision-engineered to OEM specifications for proper fit and function
  • Durable construction designed to withstand high operating temperatures and continuous rotation
  • Helps reduce belt noise and vibration
  • Essential component for maintaining proper accessory drive belt operation

URO Parts manufactures this deflection pulley as an aftermarket replacement that meets or exceeds original equipment standards. Regular inspection of deflection pulleys is recommended, as worn or damaged pulleys can cause belt wear, noise, and potential accessory drive system failure.

Awesome! !!

first time ive order from here and my experience was great! shipping was crazy fast. and they had the best price shipped on the 2jz arp head stud set i could find. also how on their site they actually list if they have the part in stock and how many which is very helpful. ive payed for parts to find out the vender didn't even have them available. which lead to more down time. and we all hate down time :)

By far the cheapest set of headers & x-pipe for my car on the market! They got them out the door first thing & sent me emails so I could track them. Very happy with this quality of service.
