Yamaha Raptor 350 ATV Widening and Shocks Conversion Kit

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 for the Raptor 350 do not include the shock brackets, but allow you to use longer shocks.  YFZ450 shocks are 15 3/4 inces long, and are ideal for the +6 inch kit (they will approximtely maintain the stock ride height).  If you use shorter shocks than these, the front ride height will end up lowered about the same amount.  If you use longer shocks, the ride height will increase, or if you use YFZ shocks with the +4.5 inch kit, the front will also be raised by about one inch because you aren’t widening the a-arms as much.

Almost any shock between the length of 13 inches and 16 1/2 inches should work, although some of them might have different width of the shock mounts top or bottom, which might require using some washers (not included) to take up the gap.  Some of the shocks that will fit on the Raptor with this kit include 400EX, 450R, YFZ450, 660R, 700R, Z400 and R450 shocks.  Stock or aftermarket shocks for these models should also fit with this kit.  In general, we recommend shocks with reservoirs (like the YFZ450’s) for heavier riders (180 lbs+) because the shocks without compression/rebound adjustment tend to have a softer ride with this kit than the Raptor’s 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.
