Quick Verdict
If you want a complete pair of guide-on posts with PVC covers and the mounting hardware included, this KOJEM kit at USD 68.34 is a practical option to weigh against your trailer setup.
Who It Suits
This kit is aimed at owners of ski boats, fishing boats, lifeboats, and motor boats who have trailer frames that fit within the U-bolt range. The adjustable bracket width lets you fine-tune the spacing, and you can choose between top or bottom mounting during installation. If you often launch alone or use a ramp with a limited dock, guide-on posts can reduce the need for a second person to steer the boat onto the trailer.
What Stands Out
The zinc-plated finish on the posts is intended to resist rust, which matters if you launch in saltwater. The PVC pole covers give your boat a softer surface to make contact with. The package also includes all mounting accessories, so you don't need to source extra U-bolts or brackets. The brackets measure 38.98 x 23.03 x 1.5 inches, giving you a useful reference for your trailer's frame. The adjustability is another nice touch: you can set the width of the brackets to match your trailer rather than forcing a one-size-fits-all spacing.
Pair 60" Boat Trailer Zinc-Plated Guide On Post Kit With PVC Poles Covers
One clear reason to consider this KOJEM kit is the combination of included hardware and adjustable design. At 60 inches, the post length sits in a common range for many trailer setups, but it's still important to check that the bracket footprint and U-bolt range match your frame before you buy. The PVC covers add a layer of protection for your boat's hull, while the zinc-plated posts are meant to hold up in damp environments.
Meaningful Trade-offs
The kit includes a single pair of guide-on posts, so if your trailer requires more than two guides or your boat is especially long, you may need to plan for additional kits. The 38.98-inch bracket length is a fixed part of the design, so you'll want to make sure it clears any other components on your trailer. An unusual frame layout could require extra measuring or modification on your end.
Bottom Line
The KOJEM pair brings together corrosion-resistant materials, PVC covers, adjustable width, and included hardware. For boaters who need a straightforward guide-on solution, it's worth a close look.
