Description

Overview

BPW H9 4218 x 120Sq dust cover lower right helps shield the brake area from spray, grit, and road debris during normal operation. As a result, it supports cleaner servicing and more consistent brake inspections on heavy trailer axles. The formed profile suits the lower right position so the cover sits correctly relative to the axle beam and brake hardware.

Features

This dust cover supports day to day durability in harsh road conditions because it acts as a physical barrier around the brake zone.

• Helps reduce direct splash and grit entering the brake area
• Supports cleaner routine inspections by keeping buildup down
• Suits the lower right mounting position for BPW H9 axle layouts
• Provides a straightforward replacement option during brake servicing

Specifications and Materials

Part number: FB5139G.

Confirm your axle and brake family before ordering because BPW systems can vary by series and position. Refer to the BPW code number designations guide for general identification context

Compatibility and Fitment

BPW H9 4218 x 120Sq dust cover lower right suits BPW H9 trailer axles that use the SN 4218 drum brake family and a 120Sq axle beam when the cover is required in the lower right position. Confirm left versus right and upper versus lower orientation before installation, then check fasteners and clearance after fitment.

Compliance and Safety

This part does not change brake compliance by itself, so follow the axle and brake manufacturer service procedures. Also, inspect brake linings, drums, cam components, and mounting points while access is available. Then recheck wheel end security and braking performance after any foundation brake work.

Trailer Applications

BPW H9 4218 x 120Sq dust cover lower right commonly applies across heavy trailers running BPW H9 square beam axles with drum brakes, including general freight, tautliner, flat top, tipper, and some container applications. It also suits fleets that operate in wet or unsealed environments where road spray and debris accelerate contamination.
