The design of the factory control arms and their mounting location at the frame are adequate for trucks that will see pavement their entire life. But, if you're like many, and are going to at least install a small leveling or lift kit and take the truck off the beaten path now and again, they are inadequate.
Not only are the factory control arms built from cheap stamped steel featuring rubber bushings at each end that tend to quickly deteriorate and warp, the physical mounting locations lends itself to a significant amount of axle bind. In a perfect world, your control arms should be parallel to the ground. This would allow uninhibited upward and downward travel of the axle, with little axle "swing." This freer range of travel would result in a substantially better performing suspension system when paired with coil springs and shocks that are capable of the new found travel. Not only will the performance be night and day difference in hard core off road situations, but even in the daily grind of speed bumps and dirt road wash board.

INTRODUCING A PERFECT WORLD SYNERGY LONG ARM UPGRADE

The Synergy Long Arm Upgrade is the solution that most have been looking for. In the past, if you wanted long arms, you were required to be running a 6" or greater lift kit, because at those heights, it is basically mandatory to keep the axle moving at all. But this left those running a leveling kit, or similar, in the dust. The Synergy system will work on trucks at stock height up to 6" of front end lift to deliver unmatched front suspension cycling.

Synergy Long Arm Upgrade as used on Project Mjolnir

We had the opportunity to get our hands on a set of pre-production Synergy Long Arms for use on our Project Mjolnir. This truck is sporting a set of our 3" Progressive Rate Coils from Eibach, Fox 3.0 12" smooth body shocks featuring DSC reservoirs, 40" tires, and a host of other suspension upgrades.

While the truck "only" has 3" of front end lift, it has articulation for days, and that would simply not be possible with standard control arms. And yes, we said 40" tires with basically a leveling kit.
