Here is the hottest shock on the market. Just released by Dave Irrgang of Irrgang Racing is their new Macro Shock. The shock comes with easy to follow instructions, threaded shock body, O-Ring dampened spring adjusting nut, long RPM ball cup, .56 shock shaft and 2-hole piston. What is great about these shocks is the easily available Associated Macro shock pistons and shock shafts fit right in. These shocks are easy to build, the bladder for the top cap resists traping air and with the double O-Rings and screw on shaft cap, they do not leak.
