If racing is part of your plans then you need to consider STEEL shock bodies as well. WHY? The standard shock bodies that come on the 2.5″ Walker Evans shocks are aluminum. These are great for most people under typical use. These are relatively easy to machine and don’t require plating. There are two negatives to this. One: the preload collar is also aluminum and tends to seize up on the shock body after you adjust your ride height a few times. If your like most racers and change your ride height a lot then this is a big issue. Steel shock bodies cure this completely because you now have dis-similar materials at the contact point (steel body and aluminum nut). Two: the steel shock bodies have less shock FADE than the aluminum bodies. The reason is this, even though the aluminum body has better heat dissipation characteristics than the steel body does, dissipation is not the real culprit here, it is expansion. Aluminum expands 5 times faster than steel. When the aluminum body expands it looses hydraulic seal with the piston inside. This basically means you have no resistance from the shock in a big hit since the fluid passes around the piston instead of through it and it’s valving. Since the steel body doesn’t expand near as much it retains the piston seal even at high temperatures limiting potential fade. Every race shock used on a Trophy Truck, Class one (unlimited) in SCORE or BITD desert racing uses a steel body. This is true for Bypass shocks, coil over shocks, Fox, King or any other competitive race shock company. We are the only company building upgraded steel bodies for Walker Evens shocks. We are serious about suspension performance. If you take your racing serious too then upgrade to our steel bodies and see the performance difference.
