Dodge W300 Series Parts & Accessories

Dodge W300 Series Parts & Accessories

The Dodge W300 Series encompasses the full range of one-ton four-wheel-drive trucks that Dodge produced under the W-Series nameplate from the early 1960s through 1980, representing the heaviest-duty segment of Dodge's legendary four-wheel-drive truck lineup. Enthusiasts and builders who seek W300 Series parts are typically restorers hunting factory-correct replacement components, hardcore off-road builders who value the platform's Dana 60 and Dana 70 axle combination, and collectors preserving these rare trucks for show or trail use. The W300 Series was built with the same proven body and frame architecture as the lighter W100 and W200 trucks but distinguished by its one-ton rated payload, heavy-duty leaf spring suspension, and availability of Dodge's largest V8 engines including the 440 B-series big-block. The Dana 60 front axle is the defining driveline feature of the W300 Series, and its upgrade potential is well-supported by Moog, Spicer, Yukon, and ARB.

Popular Upgrades

Top upgrades for the Dodge W300 Series include Moog front end rebuild kits for Dana 60 steering components, Edelbrock Performer and RPM intake manifolds for the 360 LA and 440 big-block V8 engines, MagnaFlow stainless steel exhaust headers and cat-back systems, Rancho RS9000XL adjustable shock absorbers, ARB air lockers for the Dana 60 front and Dana 70 rear differentials, and heavy-duty leaf spring packs from Deaver or National Spring. Spicer 1480-series heavy-duty U-joints are a popular driveshaft upgrade for W300 Series trucks driven hard on and off road.

Performance and Handling

The W300 Series chassis responds well to front end rebuilds that refresh Dana 60 steering geometry, eliminating the vague steering feel common on high-mileage examples. A full leaf spring replacement restores load ratings and proper ride height, and pairing Bilstein 5100 shocks front and rear makes a noticeable improvement in both on-road comfort and trail capability. Buyers who have upgraded to 35-inch or larger tires should also consider a steering stabilizer from Rancho or Bilstein to manage the additional front axle feedback through the heavy-duty Dana 60 geometry.

What is the difference between the Dodge W300 and the W300 Series?

The Dodge W300 Series refers broadly to all one-ton four-wheel-drive trucks in the W-Series lineup, including short-bed pickups, long-bed pickups, and chassis-cab configurations built across different model years. Individual W300 trucks within the series may vary by wheelbase, cab style, axle ratio, engine, and equipment package depending on the production year and trim level. When ordering suspension, axle, or driveline parts, always confirm the specific year and chassis configuration to match parts to your exact build.

Which differential locker fits the Dodge W300 Series rear axle?

The Dodge W300 Series typically uses a Dana 70 rear axle, which is compatible with ARB air lockers and Detroit Locker differentials in the correct gear diameter and spline configuration. Buyers should measure the ring gear diameter and confirm the axle shaft spline count before ordering a locker for the Dana 70 application. ARB's air locker for Dana 70 applications requires a compressor kit and air line installation, while the Detroit Locker is a fully mechanical option that requires no additional hardware.
