Top Upgrades and Repairs for the 1950 Dodge Power Wagon

The 1950 Dodge Power Wagon is one of the most beloved post-war trucks ever made—and for good reason.

The 1950 Dodge Power Wagon is one of the most beloved post-war trucks ever made—and for good reason. Built like a tank and originally intended for military and utility use, it quickly became the go-to truck for logging, farming, and just about any job that demanded muscle over speed.

But these days, restoring one isn’t just about getting it running—it’s about making it better. Whether you’re upgrading for safety, reliability, or daily drivability, here are the most important 1950 Dodge Power Wagon upgrades and repairs to tackle first.

Get it Stopping First: Brake Upgrades

Let’s face it—stock drum brakes on all four corners weren’t great even in the ‘50s. If you plan to drive your Power Wagon, upgrading the brake system is a must.

Top brake upgrades:

• Front disc brake conversion kit
  
• Dual-chamber master cylinder (safer than original single-reservoir)
  
• Stainless steel braided brake lines for better pedal feel
• Power brake booster if you want easier stops on a heavy rig

Cooling System Upgrades to Beat the Heat

These old flathead sixes love to run hot—especially when idling. Before you find yourself on the side of the road, upgrade the cooling system.

Recommended repairs/upgrades:

• Aluminum radiator with higher cooling capacity
  
• Electric fan setup for better low-speed airflow
  
• New water pump and thermostat
  
• Overflow tank and new hoses

Electrical System Modernization

The original 6V systems are charming but unreliable. Upgrading to 12V is one of the most practical improvements you can make.

12V conversion essentials:

• Modern alternator
  
• 12V coil, regulator, and battery
  
• Headlights and bulbs (LED or halogen for visibility)
  
• New wiring harness (don’t patch the old cloth-covered wires)

Suspension and Steering: Smoother Ride, Safer Handling

Power Wagons ride rough—it’s part of their DNA. But some simple upgrades can keep your kidneys intact and improve on-road control.

Upgrades to consider:

• Re-arched or replacement leaf springs
  
• Gas-charged shocks
  
• Polyurethane bushings
• Steering box rebuild or upgrade to a Saginaw swap

Drivetrain Upgrades for Modern Roads

Original gearing was made for torque, not highway cruising. If you want to drive this thing more than 45 mph, it’s time to upgrade.

Common drivetrain upgrades:

• Overdrive transmission swap (NP435 or similar)
  
• Transfer case rebuild with better bearings/seals
  
• Axle gear ratio change (helps with highway speeds)
  
• Locking hubs if you’re off-roading or looking for better fuel economy

Interior Comfort and Safety Upgrades

Cab comfort wasn’t a priority in 1950. With just a little work, you can make it quieter, cooler, and safer inside.

Interior upgrades to consider:

• Sound/heat insulation under floor and firewall
  
• Seat refoam or full replacement
  
• Three-point seat belts
  
• Windshield wiper motor conversion to electric

Tips from the Garage

Start with the safety systems—brakes and steering—before worrying about paint or accessories.
Document your wiring changes if you go 12V—it’ll save hours of head-scratching later.
If originality doesn’t matter to you, an EFI crate engine is one of the best all-around upgrades you can make.
