Dodge P320 Series Parts & Accessories

The Dodge P320 Series represents the upper-medium range of Dodge's forward-control P-series commercial van platform, configured for higher payload and extended wheelbase applications. These vans were widely used by delivery fleets, utilities, and specialty body converters, and they ran the LA-series V8 engines primarily the 318 and 360 cubic inch variants alongside the 225 Slant-Six in lighter configurations. The shared Mopar powertrain architecture makes engine and fuel system parts accessible across a wide supplier network.

Popular Upgrades

Top-ordered P320 Series parts cover ignition systems including distributor caps, rotors, spark plugs, and electronic ignition conversion kits that replace the original points-based setup. Carburetor rebuild kits for the Carter BBD and Holley units fitted to the 318 and 360 engines are high-volume items, as are exhaust manifold gaskets and replacement manifolds. Brake system parts dual-circuit master cylinders, wheel cylinders, and brake shoes and cooling system service components including thermostats and water pumps round out the most common orders.

Performance & Handling

The 360 cubic inch LA V8 in P320 Series applications is the most capable powertrain option and sees the greatest gains from exhaust header upgrades and improved carburetion. Aftermarket headers designed for the 360 LA significantly outflow the factory cast manifolds and are available from several suppliers. Urethane suspension bushings in the front end provide a firmer, more controlled response compared to deteriorated OEM rubber.

What wheelbase options did the P320 Series offer?

The P320 Series was available in multiple wheelbase configurations to accommodate different body and cargo requirements. Longer wheelbase variants were common in step-van and walk-in delivery body applications. When sourcing drive shaft components or brake line hardware, confirming the exact wheelbase and body style is essential for correct fitment.

Can I convert a P320 Series to front disc brakes?

Front disc brake conversions are available for P-series vans through specialty Mopar and classic truck parts suppliers, and the improvement in stopping performance is substantial over the stock drum configuration. Rotors, calipers, and spindle kits designed for the P-series front axle are the key components. A proportioning valve adjustment is typically needed alongside the conversion to balance front-to-rear bias correctly.
