Installation Guide

1. Ensure the trailer is on a level surface and the boat is safely secured off the trailer.
2. Remove the old roller by taking out its cotter pin and sliding the roller and washers off the shaft.
3. Clean the roller shaft to remove any rust, salt, or debris.
4. Slide one new washer onto the shaft, followed by the new wobble roller, and then the second washer.
5. Align the hole at the end of the shaft and insert the new cotter pin to secure the assembly.
6. Bend the ends of the cotter pin to lock it firmly in place. Repeat this process for all rollers.

Troubleshooting & FAQ

How do I confirm these rollers will fit my trailer?
Verify the dimensions of your current rollers and the diameter of the mounting shaft. These rollers are 3 inches wide by 5 inches long and are designed to fit a 1.125-inch (9/8") shaft.

What is the benefit of the ribbed surface design?
The ribbed surface helps reduce friction and spreads out the pressure on your boat's hull. This allows the boat to glide more smoothly during loading and launching while helping to prevent scuffs and scratches.

How often should I inspect or replace my wobble rollers?
It is best practice to inspect your rollers at the start of each boating season. Look for signs of cracking, splitting, or significant wear. Replace them immediately if any damage is found to ensure your boat remains properly supported and protected.
