Dodge P300 Parts & Accessories

The Dodge P300 was the heavy-duty entry in Dodge's forward-control van lineup, built to handle high-payload delivery and utility work. Running the same basic platform as the P100 and P200 but rated for heavier loads, the P300 commonly used the 318 and 360 cubic inch V8 engines alongside the inline-six. Parts availability is solid through Mopar and aftermarket channels, particularly for drivetrain, brake, and suspension components.

Popular Upgrades

P300 owners most commonly source exhaust manifolds, carburetor rebuild kits, distributor caps and rotors, and complete tune-up kits to bring neglected vans back to reliable service. Brake system hardware wheel cylinders, brake shoes, and master cylinders is high demand given the load-rated duty cycle these vans were designed for. Rubber restoration parts including body mounts, weatherstripping, and suspension bushings are also frequently ordered for restoration builds.

Performance & Handling

The 360 cubic inch LA V8 in P300 applications is the platform's strongest stock engine and responds well to exhaust improvements and carburetor upgrades. Heavier-duty front axle and brake components are available for P300s that carry close to their rated GVW, and upgrading to a dual-circuit master cylinder is a smart safety modification on older trucks.

What is the towing and load capacity of the Dodge P300 Van?

The P300 was typically rated at a 10,000 lb GVW in its heaviest configurations, depending on axle and suspension packages. This makes it more capable than the P200 for cargo work, and the heavier-spec brake and suspension components reflect that. Always confirm your specific year's axle rating before selecting load-rated suspension or brake parts.

Can I upgrade the P300 ignition system for better reliability?

Yes, the original point-type ignition systems on early P300 Vans are well-supported by electronic ignition conversion kits, which eliminate points maintenance entirely and improve cold-start reliability. HEI-style distributors and Mopar electronic ignition conversions are the most common upgrades. These are direct-fit for the 318 and 360 LA V8 engines.
