Detailed Description

Carlson H446 is intended for rear drum brake assemblies that rely on adjusting springs to maintain correct shoe adjustment and return action. The listed fitment covers Ford E-250 Econoline, E-350 Econoline, E-350 Econoline Club Wagon, F-250, F-250 HD, and F-350 applications across multiple model years, with notes calling out 12" x 3" brakes, 3" shoe setups, and 314 fitments.

What It Helps Address

• Weak or inconsistent drum brake shoe return.
• Improper brake shoe adjustment in the rear drum assembly.
• Noise or drag caused by worn spring components.
• Brake service needs on older Ford van and truck drum brake systems.

Installation Notes

Verify the brake shoe width, drum size, and 314 fitment notes before installation. Match the rear application exactly to the vehicle listing and inspect related drum brake hardware for wear during service. Use the fitment notes to confirm the correct Ford E-Series or F-Series configuration before replacing the springs.
