The Multiquip 302910061 Springbox Assembly MTR-120L is a genuine OEM component designed for the MTR-120L trench rammer. Sourced directly from Multiquip, this assembly meets the original build specification for the MTR-120L, so you can restore full compaction performance without guesswork. If your rammer is delivering inconsistent impact force or the springbox shows signs of fatigue or damage, this is the correct OEM replacement to get the machine back to peak operation.
Key Features
- Genuine OEM Construction — Built to the same spring rate and material spec as the original, ensuring the assembly absorbs and transfers impact energy the way the MTR-120L was engineered to deliver it.
- Direct Drop-In Fit for MTR-120L — Matches the exact mounting geometry of the trench rammer springbox housing, so installation follows the standard service procedure without adaptation.
- Confirmed MTR-120L Fitment — Verified OEM fitment for the Multiquip MTR-120L trench rammer series.
- Restores Full Impact Stroke — A worn or broken springbox reduces blow frequency and compaction depth; replacing it with this assembly brings stroke energy back to rated output.
- Structural Integrity Under Continuous Load — The springbox operates under sustained high-cycle stress; OEM-grade materials resist fatigue cracking that leads to sudden failure in demanding trench compaction work.
The springbox assembly is the heart of a rammer's reciprocating drive system. It houses the compression spring that stores and releases energy with each stroke, translating engine power into the rapid downward blows that compact soil in trenches and confined areas. When the spring or its housing wears out, impact energy drops noticeably — the machine may feel sluggish, bounce inconsistently, or lose the penetrating force needed to meet compaction specs. Replacing the springbox assembly restores the correct stroke cycle and keeps the MTR-120L performing at its rated compaction output.
