Dorman Accessory Drive Belt Idler Pulley Adjustment Bolt Kit for Dodge & Jeep — OEM-Style Hardware, Corrosion-Resistant

Dorman 917-951 is an OEM-style idler pulley adjustment bolt kit engineered to replace the original hardware and restore correct accessory belt tension on compatible Dodge and Jeep models.

If an idler pulley or its mounting hardware is missing, seized or worn, the accessory drive belt can slip, make noise or accelerate wear on alternators and air conditioning components. This bolt kit provides the specific fasteners and adjustment hardware designed to match the original equipment for the listed model years, offering a straightforward repair option without needing a full pulley assembly replacement.

Which vehicles will this Dorman kit fit?

This kit was produced to fit a set of late-1990s and early-2000s Dodge and Jeep vehicles where the original idler pulley hardware uses the same specification. Always verify fitment against your vehicle's exact make, model and trim using your VIN or the seller's garage/fitment tool before ordering.

• Compatible makes: Dodge and Jeep.
• Notable models covered: Dodge Dakota (1997–2002), Jeep Cherokee (1996–2001), Jeep Grand Cherokee (1997–1998), Jeep Wrangler (1997–2002).
• Recommended: confirm year and trim to ensure bolt length and threads match your original hardware.

What parts come in the kit and how do they perform?

The kit contains the adjustment bolt and associated fasteners sized to match factory specifications so you can reestablish proper idler pulley position and belt tension. Components are manufactured from durable materials to resist corrosion and deliver consistent torque characteristics during installation.

• Includes adjustment bolt and OEM-style nuts/washers where required.
• Machined and treated surfaces for long-lasting fit and corrosion resistance.
• Sized to restore correct pulley alignment for reliable belt routing.

How difficult is installation and what tools are needed?

Installation is typically a moderate DIY task for someone comfortable with basic hand tools and working under the hood. The job involves releasing belt tension, removing the old or damaged hardware, fitting the new bolt and retensioning the accessory belt to factory specification.

• Common tools: ratchet, appropriate sockets, torque wrench, and possibly a breaker bar.
• Expect to inspect the pulley and belt for wear and replace them if damaged.
• Follow factory torque specs and alignment checks for safe reassembly.

Why choose Dorman replacement hardware over generic fasteners?

Dorman designs many replacement parts to align with original component dimensions and function, reducing fitment guesswork and the risk of mismatched hardware causing premature failure. This kit is engineered with materials and measurements intended to restore the original mounting geometry for the idler pulley.

• Engineered to match factory thread sizes and bolt lengths for correct pulley positioning.
• Durable finishes that help resist corrosion in under-hood conditions.
• Backed by Dorman’s product expertise and automotive replacement experience.
