Installation Notes
These wobble rollers are designed for mounting on 1.125" (9/8") diameter trailer roller shafts. The rollers should be installed to allow free movement, enabling them to wobble and self-adjust to the shape of your boat’s hull. This ensures stable, cushioned support during transport and loading, while the ribbed design helps guide the boat and prevent hull damage.
Troubleshooting & FAQ
How do I know if these rollers will fit my trailer?
Measure the diameter of your trailer's existing roller shafts. These rollers are designed specifically for 1.125" (or 9/8") shafts. Also, confirm that the 3" width and 5" diameter are suitable for your boat's hull size and trailer configuration.
What is the benefit of a 'wobble' roller?
Wobble rollers pivot and tilt automatically to match the contours of your boat's hull. This provides more consistent support across a wider surface area compared to fixed rollers, reducing stress points and ensuring more stable transport.
When should I replace my boat trailer rollers?
Inspect your rollers regularly for signs of wear, such as cracking, splitting, or flat spots. If a roller no longer spins freely or has become deformed, it should be replaced immediately to prevent potential damage to your boat's hull.
What's the difference between poly rollers and rubber rollers?
Polyurethane (poly) rollers, like these, are harder and more durable than traditional rubber rollers. They are non-marking, meaning they won't leave scuffs on your hull, and are generally more resistant to cuts, abrasions, and degradation from fuel or sun exposure.
