Information about the product:
The only difference in our kits for the 2006 and newer YFZ450's is that they now have 12mm diameter tie rod threads instead of 10mm on earlier models.
Stock brake lines should be long enough to install the +4.5” kit if you disconnect the intermediate brake line support on the a-arms to provide more slack in the lines, but they will probably not be long enough for the +6.0” kit. You may also need to disconnect and reroute the brake lines over the top frame tube to allow even more slack.
Diamond J Customs does sell brake lines if you would prefer to use extended-length stainless steel braided brake lines with your widening kit.

Follow this link to take you to our billet aluminum rear wheel spacers that will widen the rear of this ATV model. The two inch wheel spacers are also a good match with the plus six inch front kits since the rear is slightly wider than the front from the factory.
