Dorman Engine Harmonic Balancer for Jeep — 594-018 direct-replacement, bonded rubber dampener

The Dorman 594-018 is a direct-replacement harmonic balancer engineered to absorb crankshaft vibration and restore original fit and function on compatible Jeep models.

This harmonic balancer assembly is built as a stress-resistant replacement part, using a robust rubber bond and production controls intended to deliver reliable tensile and impact strength. It has been dimensionally checked and functionally tested to mirror the OEM component so it installs cleanly and performs consistently. Before ordering, verify vehicle fitment—this balancer is commonly used across many Jeep Cherokee, Comanche, Grand Cherokee, TJ, Wagoneer and Wrangler model years; use your vehicle lookup to confirm compatibility for your exact application.

How does this balancer restore engine smoothness?

The balancer dampens crankshaft torsional vibration by using a bonded rubber ring that isolates and absorbs energy the engine produces. Replacing a worn or failed balancer reduces noise, protects the timing components, and helps maintain consistent engine timing behavior. It’s an essential component where radial and torsional control matter for longevity.

• Bonded rubber layer designed to resist stress and fatigue
• Matches OEM dimensions for proper alignment and pulley fit
• Helps reduce crankshaft vibration and related noise

Will this part fit my Jeep model and year?

This Dorman balancer covers a broad list of Jeep applications, but fitment should always be confirmed for your specific engine and year. Use the vehicle lookup tool or confirm the product’s Confirmed Fit indicator to ensure the correct match. If the listing shows an information icon, review the notes for additional verification steps.

• Commonly compatible with Jeep Cherokee (late 1980s–2001)
• Fits Jeep Comanche (late 1980s–early 1990s) and Wagoneer (late 1980s–1990)
• Used on Grand Cherokee, TJ and Wrangler model years listed in the product details

What are the durability and testing standards for this replacement?

Dorman subjects replacement components to dimensional checks, material validation, and functional testing to help ensure reliable service life. The materials and assembly processes are selected to provide repeatable tensile and impact resistance so the part resists common failure modes. The product is supported by Dorman’s product team and manufacturing experience.

• Dimensional verification to match original mounting and pulley interfaces
• Material validation to confirm bonding and rubber resilience
• Functional testing to verify rotational balance and performance

How should I confirm fitment before buying?

Always enter your vehicle information into the seller’s fitment tool or garage feature to confirm compatibility for year, make, model, and engine type. Check the Confirmed Fit bar; if an information icon appears, hover or click to read fitment notes. When in doubt, compare OEM part numbers or consult a mechanic for final verification.

• Use the product page vehicle lookup or garage tool first
• Read any fitment notes tied to the blue information icon
• Compare mounting bolt pattern and pulley diameter to your old balancer
