Seachoice builds affordable, dependable trailering hardware that helps you load and launch your boat straight every time. This collection covers guide-ons, keel rollers, bunk brackets and roller shafts.
Start by matching the part to your trailer setup. Keel rollers and roller shafts support the boat hull along the centerline, while bunk and bolster brackets carry the load on the outer bunks. Guide-ons help you center the boat during a windy or solo launch.
Check the inner diameter on rollers and the thread size on shafts before you order. Seachoice keeps these to common standards, so replacing a worn roller is usually a direct swap. Zinc-plated and stainless hardware resists corrosion in both fresh and salt water, which keeps your trailer rolling season after season.
A keel roller supports the boat hull along the centerline of the trailer. It lets the boat roll on and off smoothly during loading and launching and helps protect the hull bottom.
It depends on the part. Some brackets and rollers ship individually and others come in multi-packs. Check the product title and quantity on each listing before ordering.
Most Seachoice rollers and shafts use common inner diameters and thread sizes. Measure your old part and match the dimensions listed on the product page to confirm fit.
