The front is what really sucks on an FL350. Some people worry that getting the front long travel, the machine will behave odd and that they will NEED the rear. That is not the case and people who have purchased the front love the way the machine handles. I will be building two different rear kits in order to handle even bigger jumps, but you do not need it for trail riding. Hoodlum doesn't feel he needs any more travel than the little extra the Works shocks gave him. You certainly do not need to do the front and rear at the same time.
The first rear kit I will do will give 8" while using many stock components including axles. Stock travel is 5", Works shocks give 6". The setup will also use stock replacement Works shocks which many people already own. I want to keep the price down. I think this one will sell well as it will improve handling and not be that expensive.
The second kit will give 12-13" of travel replacing the entire suspension, axles, carriers, hubs,... and keep the width under 60".
I won't be working on the rear kits though until I can clear out some of the items already started like the rear bumpers and stock offset beadlocks.
