Dodge M300 Parts & Accessories

Shop Dodge M300 parts for drum-brake maintenance, engine service and load-support projects at Black Ops Auto Works. Compare DFC hardware and hydraulic components, ignition parts and Hellwig helper-spring applications for your exact chassis and installed equipment.

DFC Drum Hardware and Hydraulic Components

Choose the brake repair by function. The named M300 drum-hardware package supplies its stated retention/adjustment pieces, while shoes and drums form the friction assembly and wheel cylinders apply the shoes hydraulically. Hoses serve separate circuit connections. Inspect the actual installed drum assembly, then match full chassis, axle/side and dimensions and compare each package with the complete repair list.

Engine Service and Hellwig Load Support

Separate ignition maintenance from measured engine work. Granatelli wires and NGK plugs need the actual engine’s prescribed application; Clevite rod/cam bearings and COMP valvetrain parts need measured assembly requirements and compatible companion components. For load support, Hellwig’s current 9510 coverage includes specified 1970–1974 M300 chassis and requires a separate installation kit. Match the actual springs and mounting arrangement before combining packages.

Helper Springs and Complete Repair Contents

A helper-spring package is a different project from a replacement damper or worn suspension-joint repair. Compare the exact chassis, spring configuration and required hardware, and keep the vehicle’s load limits in the installation plan. The product title’s Ford E-350 wording is not the complete shared-application record.

A McLeod clutch reference needs the actual engine/transmission, flywheel and release combination; a filter or axle cover has its own separate application. Choose the actual repair task and full supplied contents rather than treating every component in the collection as one chassis service kit.

Frequently Asked Questions

Does the DFC hardware package supply a complete drum-brake overhaul?

It supplies its stated hardware. Shoes, drums, wheel cylinders and hoses have separate friction or hydraulic roles and may need separate orders. Inspect the actual assembly and compare exact contents before completing the repair list.

How do brake shoes and wheel cylinders differ?

Shoes supply the supported friction lining and wheel cylinders apply them hydraulically at the drum assembly. Match the actual axle, side, drum and cylinder dimensions, then choose the diagnosed repair rather than substituting one component for the other.

How do I compare NGK plug package quantities?

First choose the exact plug code required by the engine, then compare the stated box quantity with the service count needed. The current references include different pack sizes; a box is not automatically a complete engine set.

Will Ford E-350 helper springs fit my Dodge M300?

Hellwig 9510 has shared applications, including specified 1970–1974 M300 chassis, and requires an installation kit. Confirm the exact chassis, spring configuration and required mounting package with Hellwig before ordering; a Ford title alone does not exclude M300 coverage.
