The difference between the “widening kit” and the “widening and shock conversion kit” is the top shock mount brackets.  The widening kits simply relocate the stock shocks outward to match the width increase to the a-arms.  The widening and shock conversion kits provide a range of vertical locations where the stock shocks can be mounted depending on how you assemble the shock brackets.  These adjustments will allow you to use longer shocks, adjust the ride height of the front of the ATV, or both.  Some of the shocks that will fit on this model with this kit include 320mm (12.5″) shocks (300ex size). We now carry our own shocks in these sizes that work great with this kit.  Stock or aftermarket shocks for these models should fit with this kit. We recommend the +6 inch kit when using the shock conversion kit, so that there is more room to allow the shocks to operate at the best possible angle.

Stock brake lines should be long enough to install this kit if you disconnect them and reroute them over the frame tubes to provide more slack in the lines.

Diamond J Customs does sell brake lines if you would prefer to use extended-length stainless steel braided brake lines with your widening kit.

You can find more general information about our widening kits under the  Front Widening Kits menu and the Widening and Shocks Conversion Kits menu.

Note: We have started including two extra of the “high heel” looking brackets to replace the fourth a-arm widening bracket. This is to be used on the mounts nearest the steering stem to provide extra clearance for the Kawasaki 90 and other models.
