Dorman Front Upper Shock Mount Insulators 2-Pack — Direct Replacement, OE Fit

Front upper shock mount insulators by Dorman (905-499) are two precision-made replacement cushions designed to restore ride isolation and proper suspension alignment on compatible vehicles.

These Dorman insulators are engineered to match the original equipment's design and dimensions, offering a reliable, like-for-like replacement for worn or damaged mounts. Manufactured under strict quality controls, each insulator is built for long-term durability and performance. Before purchasing, confirm vehicle compatibility by entering your make, model and trim into the fitment tool to ensure an exact match.

How will these insulators affect ride comfort and noise?

Worn shock mount insulators can transmit vibration and road noise into the cabin; replacing them helps restore the intended isolation between the suspension and chassis. The Dorman 905-499 pieces cushion the shock assembly, which can reduce harshness and rattling when driving over rough surfaces.

• Replaces degraded rubber to reduce vibration transfer
• Maintains correct shock alignment to prevent uneven wear
• Reduces clunks and suspension noise at low speeds

Are these mounts a direct replacement for the original parts?

Yes — the 905-499 insulators are designed as direct replacements that mirror the original part’s shape and mounting points. That means straightforward installation and compatibility with the existing upper shock hardware on supported vehicles.

• Precision-engineered to match original dimensions
• Intended for bolt-on installation with factory components
• Sold as a convenient 2-pack to service both sides at once

What materials and testing ensure these parts last?

Dorman manufactures these insulators from robust materials chosen to withstand suspension loads and environmental exposure. Each unit goes through quality inspections and testing procedures to verify durability and consistent performance over time.

• Constructed from sturdy, automotive-grade materials
• Subjected to thorough quality control testing
• Designed to resist common wear factors like compression and weathering

How do I make sure the 905-499 fits my vehicle?

Fitment varies by make, model and trim, so Dorman recommends using the online garage tool or your vehicle’s VIN to confirm compatibility. Verifying fit before purchase prevents returns and ensures the insulators will mount correctly with your existing shock hardware.

• Enter make, model and trim in the fitment lookup
• Check part number 905-499 against OEM cross-references
• Compare mounting points and dimensions if unsure
