Extreme Max 3005.2184 Adjustable Roller Guide-On System

This is my third set of guide rails.All other ones failed due to being strong enough to support my boat.My boat load quite easily now.This is very good.

It Fit Perfectly on my 2011 LOWE 175 STINGER & TRAILER. Heavy Duty and High Quality. Easy To Install Using A Helper, Two 9/16 Wrenches and a 9/16 Deep Well Socket. I'm also impressed that the company provided 2 Acorn Nuts for the outside verticals that will keep you from getting cut on an exposed bolt.

*** Post-purchase Update ***We used the guides quite a few times this season without incident except for one time I pulled the trailer of the water too quickly and the roller got lodged under the boat's bumprail as the it was coming out of the water. It pulled the bumprail out of the hull but I was able to repair it. I wish these were about 1' taller to avoid damage to my boat in the future when crosswinds push the boat against a roller as we pull out. Next season I'll try and engineer something to increase the height. Otherwise I'm pretty happy with the guides.Original review:My trailer has a little step where the guide was installed. I have steps ahead and behind both fenders. I had to drill through the step with a stepped bit which wasn't hard. I was able to drill the holes and install the bumpers with the boat on the trailer.My first frustration was how easily the bottom plate bent. The plate is way bigger than my frame rail is wide so a lot of the bottom plate hangs out in the air. When tightening the bolts the plate began to bend. Not sure if it'll impact long-term functionality but I'm concerned about the strength.My second frustration was that they shorted me two nuts. A trip to the hardware store was required.The instructions were clear enough if you think them through. They include a list of the included parts and show a picture of them all together with arrows pointing to where everything goes and somewhat brief installation notes. It's not a step-by-step IKEA style set of instructions, so you'll have to be somewhat mechanically inclined to install them. I suspect they're not super in-depth because all trailers differ. I pulled on them pretty hard once they were installed and they seem pretty stout so they should do well. The top of the bumper is tapered to allow the boat to pop down over the guide if it should be against it and foul on the bumprail when you trailer it out. Probably best to go slow.These guides will help us a lot. Our boat has a fairly deep draft so when we take out only the very front touches the bunking which constantly led to the boat being off center because it's impossible to get it directly over the trailer and keep it that way when taking it out.We're headed on a multi-day lake trip this week and we'll be putting in and taking out a lot. If these rails don't work or fail in some way, I'll post an update. If I don't, assume all went well!

I really liked how the guides were adjustable for different angles and Heights and it's very sturdy and worked great for me

Weather you use them for loading to give you a visual or as a means to physically guide you onto the trailer they are very handy. Strong 2" steel square tube, not plastic. They are so good someone just stole one of mine and now I have to buy another one.

Made loading my boat alone much easier!

They state they have a bolt kit to fit over 5" tall trailer frames but the kit is unavailable.

This product worked perfectly for me! I was able to get my 18.5' open Boe ski boat on to the trailer all-by-myself!!Very happy 😊Top-notch quality... very heavy dutyThanks!

What a difference these make for trailering my inflatable! So easy, perfectly aligned every time. Rollers are fantastic and the quality seems very good. Rock solid.

Used the wrong bolts at the start. I had to remove the bolts and had to switch out the new ones. Take time to figure out the length of the bolts and where they go.

Nice solid quality guides.

Very easy to use and install and great value for your money

Il a été très facile à installé sur ma remorque. Nous nous en sommes servi 1 fois depuis l'installation et cela a été très efficace. Le produit a bien fait son travail.
