The Multiquip 4388 Stabilizer Strut Gen 4 is a genuine OEM stabilizer strut designed for MD80, MD105, PRX, HTX44, and STX55 series ride-on power trowels, as well as WRS series ride-on roller screeds. As a direct Multiquip OEM component, the 4388 is built to the same specification as the original part installed at the factory, ensuring a correct, trouble-free installation. This strut is confirmed to fit HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55Y6, STX55J6, MD80, MD105, PRX, WRSPUDF, WRS5200, and WRS5200DFPU models. When your machine is due for service or the existing strut shows signs of wear, replacing it with the correct Multiquip 4388 keeps the stabilizer system performing as intended.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the strut seats and loads correctly within the stabilizer assembly without adjustment or rework.
- Direct-Fit Replacement — Matches the mounting geometry and attachment points of the original Gen 4 stabilizer strut, allowing straightforward installation on compatible machines.
- Broad Ride-On Trowel and Screed Compatibility — Verified for HTX44, STX55, MD80, MD105, and PRX ride-on trowels, plus WRSPUDF, WRS5200, and WRS5200DFPU roller screeds.
- Structural Integrity Under Load — A correctly functioning stabilizer strut maintains frame rigidity during operation; a worn or cracked strut can introduce unwanted flex that affects blade pitch control and finish quality.
- Long-Term Fit Assurance — OEM sourcing means the 4388 matches the material grade and dimensional spec of the part it replaces, supporting the service life of the surrounding stabilizer components.
The stabilizer strut is a structural support component within the stabilizer system of ride-on trowels and roller screeds. It bears and distributes the mechanical loads generated during operation, keeping the frame and working components in proper alignment. When a stabilizer strut cracks, bends, or wears at its connection points, the machine can develop unwanted movement or misalignment that compromises both finish quality and operator control. Replacing a failed strut promptly restores the structural foundation that the rest of the stabilizer system depends on.
