AULINK Harmonic Balancer Crankshaft Pulley for 3.0/3.2/3.6L V6 — Direct-Fit, Bonded Rubber Damper

The AULINK 594-405 harmonic balancer is a direct-fit crankshaft pulley assembly designed to reduce V6 engine vibration and restore smooth operation on compatible Chrysler, Dodge, Jeep, Ram, and VW Routan vehicles.

This replacement harmonic balancer (OEM references 594-405 / 5184293AC / 7B0105251B, among others) is produced under TS16949-quality processes and combines ductile steel with a bonded rubber damping ring to control torsional vibration. It’s intended for 3.0L, 3.2L and 3.6L V6 engines and targets models from 2011–2020 where the factory crank pulley has worn, cracked, or allowed excessive engine shake.

How does this balancer improve engine smoothness?

The balancer’s rubber damper isolates and absorbs crankshaft torsional pulses that cause vibration and noise. By maintaining correct damping characteristics, it helps the accessory drive and engine run with less harshness under load and at idle.

• Rubber vibration ring bonded to ductile steel for consistent damping.
• Precision machining for concentric rotation and reduced wobble.
• OEM-equivalent fit to preserve factory accessory alignment.

Will this part fit my vehicle and how do I confirm compatibility?

The AULINK 594-405 replaces several factory part numbers and fits many 3.0L–3.6L V6 applications across Chrysler, Dodge, Jeep, Ram and Volkswagen Routan lines. Verify fit by matching the OEM part number or cross-referencing your vehicle year, make, model and engine size.

• Cross-references include 594405, 5184293AG, 5184293AH and 7B0105251C/D.
• Common compatible models: Chrysler 200/300, Dodge Charger/Challenger, Jeep Grand Cherokee/Wrangler, Ram 1500, VW Routan.
• Check engine displacement (3.0L, 3.2L, 3.6L V6) before ordering.

What quality checks and warranty cover this replacement part?

AULINK parts are made in TS16949-certified facilities with material verification and functional testing to ensure durability and correct performance. The product includes a one-year replacement or 50,000 km coverage for defects, and customer support is available through the seller channel.

• Manufactured under automotive quality standards (TS16949).
• Material validation and functional testing performed before shipment.
• One-year replacement or 50,000 km warranty with seller support.

How difficult is installation and what should I watch for?

Installation requires basic mechanical tools and a proper crank pulley installer/remover to avoid damaging the new balancer or crank snout. Follow torque specs from a repair manual and inspect the keyway, crank threads, and accessory belt alignment before final assembly.

• Use the correct pulley puller/installer to prevent damage.
• Replace any damaged crankshaft seal or accessory belts while accessible.
• Torque to factory specifications and confirm pulley runout is minimal.

Who is this for? The AULINK 594-405 harmonic balancer is aimed at DIY mechanics, independent repair shops, and fleet managers who need a reliable, OEM-equivalent crankshaft pulley for 3.0L–3.6L V6 Chrysler, Dodge, Jeep, Ram, and VW Routan engines. Choose this unit when the original balancer shows cracking, delamination, oil contamination, or causes noticeable engine vibration — it restores proper damping, maintains accessory alignment, and helps protect the timing and accessory drive systems when installed correctly.
