The Honda 81134-V09-A01 Seat Spring is a genuine OEM component designed for the HA4118 and HA4120 lawn tractors. As a direct OEM replacement, this part is manufactured to the same specifications as the original, ensuring a proper fit with no guesswork. Honda supersedes parts at serial number breaks, so verify your machine's serial number against the fitment table before ordering to confirm this is the correct spring for your tractor.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this Seat Spring matches the original component your HA4118 or HA4120 left the factory with, delivering the correct tension and geometry for proper seat function.
- Exact Replacement Fit — designed as a drop-in replacement for the HA4118 and HA4120 lawn tractors, this part installs the same way as the original with no adaptation required.
- Serial Number Verification Recommended — Honda updates parts at production breaks, so cross-reference your tractor's serial number against the fitment table to confirm part number 81134-V09-A01 is correct for your unit.
The seat spring supports the operator seat suspension system on the HA4118 and HA4120 lawn tractors, maintaining the correct tension that allows the seat to flex and return to position under the operator's weight. A worn or broken seat spring can result in a seat that sits too low, bottoms out, or no longer returns properly — reducing operator comfort during extended mowing sessions and potentially affecting the seat's ability to stay in its set position over rough terrain.
