Detailed Description

The WAI DST3890 ignition distributor is a direct-fit replacement for older Chrysler, Dodge, and Plymouth vehicles that use vacuum or single-pickup configurations listed in the fitment data. Built with all-new components, it is intended to restore reliable spark timing and stable ignition operation in applications such as the Dodge B150, D150, W150, and Dakota, along with Chrysler LeBaron, Newport, and Town & Country models. The aluminum housing supports durability, while the magnetic distributor design and included cap and rotor help simplify service replacement. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Distributor Helps Address

• Hard starting caused by worn distributor internals
• Misfire or rough running from inconsistent spark timing
• Ignition scatter related to aging vacuum or pickup components
• Cap and rotor wear that can affect spark delivery
• Service downtime when replacing a failed distributor assembly

Installation Notes and Tips

Verify engine configuration and distributor style before installation. This part is listed for specific Dodge, Chrysler, and Plymouth applications with notes such as w/Vacuum and w/Single Pickup, so match the vehicle details carefully. Set base timing after installation and confirm proper rotor alignment and cap engagement before starting the engine. The DST3890 is a complete unit, but ignition coil replacement is not included.
