Troubleshooting & FAQ
How do I know if this roller assembly will fit my trailer?
This assembly fits boat trailers with a 1/2 inch shaft mounting bracket. Measure your existing bracket and bolt diameter to confirm. You should also select the correct size (e.g., 5" x 3" or 7" x 4") that matches your old roller.
What is the difference between the V-Shape and W-Shape rollers?
The shape helps guide your boat's keel. A V-Shape roller is a common, effective design for most hulls. A W-Shape roller provides a wider, more defined channel which can offer additional stability for certain hull designs during loading.
When should I replace my bow roller?
Inspect your roller regularly for signs of wear, such as deep grooves, cracks, or material degradation (becoming brittle or soft). You should also replace it if it is seized and no longer spins freely, as this can cause scuffing on your boat's hull.
