Smooth Launch. Easy Retrieval. Every Time.

A worn or missing bow roller turns every boat launch into a struggle — and risks scratching your hull in the process. The RIVOWON Boat Trailer Bow Roller is a direct-fit replacement that guides your boat smoothly onto the trailer and protects your hull from contact damage, trip after trip.

🔄 Double-Cone Design for Centered Guidance

Symmetrical double-cone profile naturally centers the boat’s keel as it loads onto the trailer — reducing side-to-side movement and hull contact.
Smooth rolling surface minimizes friction during launch and retrieval, making solo trailering easier and safer.

🛡️ Durable PE Construction

Made from high-density polyethylene (PE) — impact-resistant, UV-stable, and corrosion-proof in both freshwater and saltwater environments.
Outlasts rubber rollers that crack and degrade over time.

📏 Precise Dimensions for a Reliable Fit

Outer diameter: 7.6cm / 3in
Height: 7.05cm / 2.78in
Center shaft hole: 1.35cm / 0.53in — fits standard trailer roller shafts and bolts.

⚡ Easy Drop-In Replacement

Fits most standard boat trailer bunk brackets, bow stops, and roller guides.
No special tools required — slide onto the shaft, secure, and you’re ready to launch.

Small part. Big difference. That’s RIVOWON.

Fit perfectly. Fit right in the pre-existing holes.

Easy install. Love the color. A little stiff at first, boat had an issue sliding on the rubber the first time but its good after we used it a few times. Would buy again

Very good replacement part for boat trailer, well made, good value

Great product love the material it‘s strong and should last a while will definitely buy again if needed

This is great quality. I did substitute the bolt for a stainless one, but the rubber holds up well, looks nice too.

Seems good so far hopefully it will hold up long term

Works great and fit perfectly

Installed it on my Karavan double jetski trailer. Back in business and ready for the summer season.

Fit perfect and good quality. Just what my husband wanted to fix his trailer

Jetski trailer Roller. Good replacement for Jetski trailers

Well made, good bolt and nut, fit in place beautifully and it works.

I purchased this to replace the bow stop for my 1994 Bass Tracker TX17. It was a direct fit replacement and went on easily. It is harder than the rubber roller it replaced, but has some "give" to allow tight sinching of the strap/hook.

Replaced the roller that I had on my watercraft trailer that was over 8 years old and wearing out. This roller was a perfect fit, a little firmer than my original roller, a good thing, and took less that 1 minute to install. High quality and I would purchase again.
