This kit has continued to grow in popularity each year, and we're all set to send them out for another season in the snow!!! This year we are adding the disc-brakes rotation-limiting rubber stops in with each kit!

We've been doing a lot of development and testing on this kit, and it is a blast in the snow!  This kit allows you to purchase Polaris Gripper or Pro/Steer Skis (new or used ones found on ebay) and bolt them directly to your ATV.

Ideal use conditions for this kit is snow from 2 to 4 inches deep which can have occasional deep areas crossable with momentum. Hard packed snow trails and snow covered ice are also ideal conditions. Use in deep snow is not feasible without rear tracks. Good snow tires improve performance. Studded tires as shown in the pictures further increase performance.

More information about the product:

Steel brackets are CNC cut with a LASER for accuracy. Parts will come with industrial gloss black powder coating for corrosion resistance. All the mounting hardware shown is included (skis, loops and carbides not included with the "Ski Conversion Kit").

The kit works on both of the two most popular bolt patterns on ATVs and UTVs.  The two bolt patterns are 4x144mm and 4x156mm. 

The 4x144mm bolt pattern is a little more than 5 5/8" from center to center across opposite hub studs. Here is a list of ATV's with this bolt pattern
(not that we have tried them on all of these models, but if you find issues with any of them - please contact us):
Honda 700XX, 450R, 400EX, 400X, 300EX, 300X, 250EX, 250X, 250R
Suzuki LTR-450, LT-Z400, LT-Z250
Kawasaki KFX700, KFX450R, KFX400,
Arctic Cat DVX400, DVX250,
Can-Am DS450

The 4x156mm bolt pattern is a little more than 6 1/8" from center to center across opposite hub studs. Here is a list of ATV's with this bolt pattern
(not that we have tried them on all of these models, but if you find issues with any of them - please contact us):
Yamaha 700R, 660R, Banshee, Blaster, Warrior, YFZ450's, Raptor 350, Raptor 250, Raptor 125, Timberwolf
Kawasaki Tecate ('85 - '88), Mohave, Lakota. 
Polaris Predator 500, Outlaw 450/525, Trail Boss, Cyclone, Trail Blazer, Xplorer, Magnum, Xpedition, Sportsman, Trail Boss, Scrambler, Sport 400L, Big Boss, Ranger, RZR

 

To limit the rotation of the skis, we now include rubber bumpers with mounting hardware. They mount to the front brake discs through the venting holes and press against the brake caliper to limit rotation of the hub. Details of how to install these stops are explained in the instructions.

If your ATV has drum brakes, you can run a bungee cord from each ski loop to the front bumper, this is the simplest solution that is also the most effective.

This kit will work with the Polaris "PRO-STEER Ski" part number 2879152-070 or with the Polaris "GRIPPER ski" part number 2877679-070.  The kits we now sell (above) will work with either of these ski models, but WILL NOT work with the SkiDoo Precision skis which our previous model was used on.

We picked the Polaris skis because of their wide availability at dealers and on eBay. Polaris skis can easily be found on ebay anytime. What you need to complete the kit is a pair of plastic skis, a pair of ski loops for the front of the skis and a set of carbide runners for the bottom of the skis. Of course for your convenience, we sell these skis above. The price is the same as what you will find at the Polaris dealer.

  

       

This kit requires no cutting or welding if used with Polaris skis we listed above, and can be installed easily in an hour or two for a typical home mechanic.  The skis just bolt to the brackets using the hardware supplied in the kit.  The brackets bolt directly to the ATV hubs, using the stock lug nuts (flip the lug nuts around so they have a flat surface against the brackets instead of the tapered surface used to center the wheels).  No parts other than the tires and wheels need to be removed from the ATV.

The kit works especially well with the ATV widening kits that we offer.

It is fun to play around in the snow with a sport quad with tires, but most of the drag that slows you down is caused by the front wheels pushing through the snow and tires do not turn well on snow in many conditions.  With skis you go over the snow with the front and your ability to steer is greatly improved.  We've ridden our test machines side by side with snowmobiles in the ditches and over the snow drifts, and have had a great time doing it.

You can run in the snow with your stock tires, but we have found that MUD SHARK tires are the best for being able to get incredible traction in almost all conditions.  They are highly recommended if you are looking for a special snow tire.  Another option is from www.etvdesign.com.  They have a paddle tire for the rear that really gets you through the deep snow!  These can also be combined with track systems on the rear for the ultimate solution!

The goal of Diamond J Customs is to develop and offer products that add performance to the ATV without the enormous price tag found on other ATV aftermarket products. We do this by designing kits that will allow use of as many stock components as possible, and allow you to mount higher performing parts from other ATV’s on your model. These parts are often available at reasonable prices on eBay, saving you money. We've sold literally hundreds of these kits to other “Quad Fanatics” and from the feedback from customers on eBay you can see that they have been more than satisfied with the products. We work hard to design products that maximize the performance of your ATV while keeping prices as low as possible. Safety is not something that will be compromised.
