Key Features
- Correct Spring Rate for Rammer Operation — Manufactured to the precise tension specification required for consistent, full-stroke tamping performance on Multiquip rammer equipment.
- Genuine OEM Part — Sourced directly from Multiquip, ensuring the material grade and dimensional tolerances match the original component exactly.
- Broad Rammer Fitment — Confirmed fit for MT-74F, MT-74FA, MT74FAF, MT-75H, MT75HS, MT-84F, and MT-84FA series rammers under a single part number.
- Restores Full Compaction Force — A worn or fatigued main spring reduces impact energy and compaction effectiveness; replacing it brings the machine back to its rated output.
- Verified by Part Number — Order with confidence using Multiquip part number 355447270 to confirm you're getting the correct spring for your machine.
The main spring is the core energy-transfer component in a rammer. It stores and releases kinetic energy with each stroke of the engine, driving the foot down into the ground to compact soil, gravel, or granular fill. When the main spring weakens, cracks, or breaks, the rammer loses striking force, produces inconsistent compaction depth, or stops cycling altogether — making timely replacement essential for effective trench and confined-area compaction work.
