Information about the product:

Stock brake lines on the Kawasaki KFX-450R WILL NOT be long enough to install the +6.0" kit but should be long enough for the +4.5" kit.  Usually we try to let customers know if they will be long enough, and if they can get by without extended brake lines, but in this case there is no alternative.

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.
