Yamaha Warrior ATV Widening and Shock Conversion Kit

We now carry our own 15.75″ shocks in these sizes that work great with this kit! (find below in ‘related products’)

The Yamaha Warrior Kits for 1989 and older are completely different kits than the 1990 and newer kits. There was a major frame and suspension change for the 1990 model year. This kit is for 1990 and newer models.

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 the 300EX with this kit include 400EX, 450R, YFZ450, 660R, 700R, Z400 and R450 shocks.  Stock or aftermarket shocks for these models should fit with this kit.  In general, we recommend shocks with reservoirs (like the 450R’s) for heavier riders (180 lbs+) because the shocks without compression/rebound adjustment tend to have a softer ride with this kit than the stock suspension.

Stock brake lines should be long enough to install either the +4.5” or the +6.0″ kit if you disconnect the intermediate brake line support on the a-arms 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.
