Our models will fit most every make and model on the market. Our universal 46 inch spoiler is typically for the larger and wider machines. The universal 40 inch model typically goes on the 50 inch models. All mounting hardware and parts are identical besides the width of the spoiler. The only limiting factor is what accessories you have installed in the back that could alter the mounting of the spoiler.

Our manufacture recommendations call for only 2-3 inches above the roof line. You want most of the spoiler behind and below the roof to be able to direct that air to the areas that cause most of the issues. Realistically, you need it just high enough to collect air.

Yes. The second you start moving you can feel the air being pushed down and start flowing down the back. Obviously the faster you go the more forceful the air will be, as long as you are moving forward, the spoiler is helping to cut down the dust from behind.

That is hard to determine in percentages, but we would say that there is nothing on the market that comes close to our product in reducing the dust and dirt issues that these machines cause. Our spoiler completely changes the aerodynamics behind the machines which blocks the dust and dirt that billows up from behind the machines. This is the most problematic area that causes the most issues with both cargo dust, infiltration of dust on the back seat passengers and increased recirculated interior cab dust. Also, if you listen and apply the advice we offer to maximize the results, you will have even greater results.

The short answer is no. Unfortunately most rear windshields prevent our mounting hardware from attaching to the left and right side of the roll cage. The will work with rear mesh or soft coverings, although we highly recommend nothing is placed on the back but our spoiler.

Hinder. It’s a pretty accepted and a known fact that the second you add windshields, the dust problems immediately become worse. The more you encapsulate the cab with windshields, coverings and partial cab enclosures, the dust magnifies. Most dealers are aware of this but don’t want to jeopardize their ability to make money on aftermarket products. They will continue to push windshields and even recommend them for all dust related issues. It’s very counterintuitive and costs customers thousands of unnecessary expenses. We realize that in certain conditions that a front full windshield is wonderful and useful. But, you can still achieve similar results with a front half shield or something that allows as much ventilation coming through the front. The more ventilation, the better the dust control and maximization of the spoiler. We sell a lot of product to customers that have full front windshields and they are all still happy. We offer this information to understand and gain the maximum benefit possible if desired.

We recommend a 30-40% angle off the back of the roof. This can be better seen and established looking at the machine from the side. You want the spoiler to be in a position where the spoiler support arms are leaning in toward the back of the roof, and then you can fully adjust the curvature of the spoiler to that 30-40 degree mark. The beauty of our design is that this is fully adjustable so it enables you to play around with this or set it up personally based on your machine and what you seem to think works best. Some set ups have accessories and tires etc. that can require some adjustment of the spoiler to shoot the air in the right directions. This is why we made it fully adjustable.

Yes. Full front windshields are notorious for causing even worse dust issues, but a lot of our customers have already purchased these products and understandably don’t want to get rid of them. We also understand that in certain circumstances the front windshield can be so useful. But we can tell you the second you add a front windshield, you dust problems will become twice as bad, if not more. We currently recommend a front half windshield, or a product that allows as much ventilation to come through the front. This will maximize the results that our spoiler offers.
