JMC +3" kits for the larger sport model Quads consist of 8 high quality CNC machined 4140 steel spacers, gold zinc plated for excellent corrosion resistance and durability. All you have to do is remove your wheel, tighten the spacers on the stock studs and replace the wheel. In just a few minutes you can radically alter the look and ride of your stock machine. The weight and load is equally supported across the hub so it is a very strong system. This kit contains enough spacers for two wheels and fits front or rear and increases the wheel track by 3 inches overall. Wider spacer kits than this can put extra stress on your axle, so be wary of any advice to the contrary. Also, plastic/graphite style spacers do not allow the wheel nuts to stay the correct tension and always need tightening. Eventually, they will crack.
