Four Seasons Accessory Drive Belt Idler Pulley Spacer

Four Seasons Accessory Drive Belt Idler Pulley Spacers, also sold as idler pulley shoulder bushings, are replacement hardware for serpentine and accessory drive belt idler and tensioner pulley assemblies. The spacer sits between the idler pulley and its mounting point. It keeps the pulley positioned correctly so the belt stays aligned and the pulley turns smoothly.

Key Features:

• Steel construction for durability under the loads and heat of an accessory drive
• Precision-machined for consistent fit
• OE-style design for dependable replacement of worn or missing spacers and shoulder bushings
• Designed for use with idler pulleys on hang-on units
• Helps maintain proper pulley alignment and belt tracking

Four Seasons is part of the SMP Temperature Control Division and supplies a full line of replacement climate control and drive belt system components. This product line is a practical, economical way to restore an idler pulley installation when the original spacer or bushing has worn out or gone missing.
