Wacker Neuson 5000088535 Shockmount 40 X 20, 45 Shore

The Wacker Neuson is a genuine OEM Shockmount 40 X 20, 45 Shore designed for the GP, GPS, and G Series portable generators and LTN and LTV light towers. As a direct OEM replacement sourced from Wacker Neuson, part meets the original material and durometer specifications required for proper vibration isolation in these machines. This shockmount fits an extensive range of models including the GP3800, GP4000, GP5600, GP6600, GPS5600, GPS6600, GPS8500, GPS9700, G Series 50Hz generators, and the LTN6K, LTN8K, LTV6K, and LTV8K light towers. Verify your model number before ordering to confirm fitment.

Key Features

• Correct 45 Shore Durometer Rating — The 45 Shore hardness is matched to the vibration frequency and load characteristics of Wacker Neuson GP, GPS, G Series, and LTN/LTV platforms, ensuring the mount absorbs vibration rather than transmitting it to the frame.
• Genuine OEM Component — Manufactured to Wacker Neuson's original material specification, this shockmount replicates the compression set resistance and deflection range of the part it replaces, with no guesswork on material grade.
• Direct Drop-In Replacement — The 40 x 20 mm dimensions match the original mounting footprint, allowing straightforward installation without modification to existing hardware or mounting points.
• Broad Model Coverage — A single part number covers the GP3800, GP4000, GP5600A, GP6600A, GPS5600A, GPS6600A, GPS8500, GPS9700, multiple 50Hz G Series generators, and the LTN6K, LTN8K, LTV6K, and LTV8K light towers.
• Protects Engine and Alternator Mounts — A worn or hardened shockmount transfers engine vibration directly into the generator frame, accelerating fatigue in surrounding components and increasing noise output; replacing it restores proper isolation.

A shockmount is a rubber-and-metal vibration isolator positioned between the engine or generator assembly and the machine frame. Its primary job is to absorb and dampen the cyclic vibration produced by a running engine, preventing that energy from transferring into the chassis, housing panels, and electrical connections. The durometer rating — 45 Shore in this case — describes the stiffness of the rubber compound; too soft and the mount collapses under load, too hard and it ceases to absorb vibration effectively. When a shockmount degrades, cracks, or hardens with age, vibration levels throughout the machine increase noticeably, fasteners work loose more quickly, and sensitive alternator components experience accelerated wear.
