>>> JD use to sell some 4" flares that had no exposed mounting hardware.......they were the "flexi-glass" version that were really more for street use.... the used a flexible glass & mat ,but were way stiffer than the "trail flex" 4" flares that are on crazy horse ... the were supposed to bring out a new version ,but it never happened yet....... here's a copy&paste from one of JD's pages>>>>>>>With trails getting harder and tires getting bigger, it was time to advance Duff's popular 4" flexi-glass flare to be able to handle the use of today's hardcore wheeler or urban driving abuse. Based on the same two-piece design as the original Trail Flex flare, we have built prototypes out of the same space-age poly that is used in Duff's top selling UFO flares. The smooth outer finish with no visible mounting screws makes for a grea look. They are ideal for a daily driver or wide tires and can be easily painted.
Look for the 4" Trail Flares to be released January 2008.
