Description
Tie Down Engineering 86488 is a 4-inch rubber bow roller for a 1/2-inch shaft. Current listings tie LNS SKU 241-86488 to Tie Down part 86488 and describe it as a standard trailer bow roller used to support and guide the bow during loading, launching, and trailering.
This is a soft brown rubber style roller, made for trailer winch-stand and bow-stop applications where the roller helps cushion the bow and reduce wear during retrieval and transport. Current market listings consistently place it in the common 4-inch roller category for smaller trailer bow-support setups.

Compatibility / Application
Commonly used on boat trailers that accept a 4-inch bow roller with a 1/2-inch shaft. Fitment is based on the trailer’s bow-stop bracket width, shaft diameter, and the roller size already in use rather than on a specific boat engine or boat brand.
Fitment Notice
Please confirm the trailer uses a 4-inch roller and 1/2-inch shaft before ordering. Matching the existing roller width and shaft diameter is the key fitment check on this part.
When This Part Needs Replacement
Replace this bow roller when:
- the rubber has hardened, cracked, or split
- flat spots or deformation have developed
- the bow no longer loads smoothly against the stop
- the old roller has worn enough to reduce support or cushioning
Installation Notes
- Confirm the existing shaft diameter is 1/2 inch.
- Match the replacement roller width to the current bow-stop setup.
- Inspect the shaft, end caps, and mounting bracket while replacing the roller.
- A fresh roller can help the bow load more smoothly and reduce scuffing at the contact point.

Parts Desk Insight
Bow rollers are simple trailer parts, but the wrong width or shaft size turns into an annoying fitment problem fast. On this one, the two details that matter most are the 4-inch roller length and the 1/2-inch shaft hole. If those match the trailer, it is the right lane.
