BOSS 143-3667 – BRX48 Driver Side Frame Assembly
Restore the rugged integrity and precise alignment of your BOSS SR MAG BRX48 broom with the genuine 143‑3667 BRX48 Driver Side Frame Assembly. This factory‑engineered part serves as a key structural element on the driver side of the broom’s frame, anchoring caster wheels, side brackets, and other frame components to ensure optimal performance, safety, and durability.
Product Features & Benefits
-
OEM Built for Compatibility: This driver side frame assembly is manufactured by BOSS to exact specifications for the BRX48 broom within the SR MAG line. Ensures precise fit with other OEM parts like caster assemblies, kickstands, bristle mounts, and the overall frame.
-
Structural Stability & Strength: Under heavy load, snow, and debris, the frame takes considerable stress. A high‑quality driver side frame minimizes flex or twisting, maintaining correct alignment of bristles and caster wheels. This helps reduce uneven wear, vibration, and loss of sweeping efficiency.
-
Extended Equipment Life: When the frame is solid, other wear points—such as bolts, welds, bristles, caster wheels—see less stress. Replacing a worn or damaged driver side frame helps protect these associated components and gives the entire broom assembly a longer productive life.
-
Simplifies Maintenance & Repairs: With a solid, factory‑correct frame in place, diagnosing and repairing related issues (like misalignment, loose components, or side‑lean) becomes easier. Installation of this assembly restores geometry, making subsequent maintenance more straightforward.
Why It Matters
Misalignment, bending, or damage in the frame assembly can cause many issues: uneven brushing, excessive vibration, premature component failures (caster wear, bracket fatigue), and even safety risks when attachments aren’t secure. Using the correct driver side frame assembly restores the broom’s intended geometry and performance, ensuring clean sweeping, safer operation, and a longer lifespan for your broom system.
