Extreme Max 3005-2199 Extreme Max 4' Bunk Trailer Guide-On Pair

Always skeptical when buying something online - sight unseen - however these trailer bumpers are top-notch quality, easy to install and had all of the necessary hardware to do the job. Hats off to Extreme Max for a great product.

Very heavy duty just what I wanted

Great product, very easy to install. Works great with my Bassboat, makes loading on a windy day very helpful, keeps the the boat in line.

These are worth every penny when it comes to loading your boat onto the trailer on a windy day. Quality product and was really easy to install.

Longer bolts and it fit 5" frame,bolted bunks straight to angle brackets.

good product, but the box wasn't heavy enough for the weight of the product. The box was torn up so i had to check that it was all there. it was so that was good. I haven't put these on my trailer yet but they are very well made. As for the box, maybe it was loaded by the Samsonite gorilla, lol.

Very good product it was a lot heavier than expected worked out great

Product does not extend far enough to be able to load my boat. I will be retuning it to the nearest Walmart and shopping elsewhere for a product that will work. I also twice attempted to call Extreme Max, the product dealer, left two messages, and after four days still have not heard from them.

Product build seems to be good quality but be cautious of fit, the outside hull of your boat has to be almost flush with your trailer frame for these to work. I attempted to go off the measurements that were described but these do not come close to being wide enough/adustable enough. I will have to flip the brackets to get the width I need but will also have to fabricate some spacers to raise the brackets on the trailer frame so the bunks will actually guide the sides/hull of my boat. Overall, good quality but poor design when it comes to length of brackets and adjustability to different types of trailers/boats.
