The 300EX kits will also fit all year models of the older (late 80’s / early 90’s) 250X’s that used the same frame as the 300EX.  The 250EX is not the same as those older 250X’s, and requires a diiferent kit (also listed on this website).  Then, in 2010 Honda went and renamed the 250EX to the 250X.  The new 250X’s are actually 250EX’s on our website.  (Sorry for the confusion this may cause – its Honda’s fault.)

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.
