American Boat Trailer Bunks, Previously known as Eastern alloy bunk protection covers, we have re-branded these bunks to be known as Ultra Alloy which are a direct upgrade / replacement for your existing bunks that may have worn down carpet or rubber coverings.
These plastic profiles are designed to suit bunks 120mm / 130mm wide. Generally found on larger American style boat trailers; These plastic boat trailer parts will not only help protect your boat, but make launching and retrieving your boat a lot easier!
Plastic bunk covers are ideal for use on large American style trailers here in Australia. Some of the more common branded trailers include:
Great quality and exactly as described. The grooved design looks good and feels durable. Easy to fit and does the job perfectly. Very happy with the purchase and would recommend.

Can’t beat the price tag, just have to do wiring but tells you how to connect it. Hassle free
