"I replaced the shocks on my Pro-Line PRO-2 with the Pro-Specs to test them out at our local track and found them to be more consistent and stable. Through bumpy sections of the track, the Pro-Specs were responsive and provided consistent traction throughout the course. The most important difference in these shocks is their consistency. Throughout an entire evening of racing, the Pro-Spec shocks operated smoothly as expected lap after lap. The Pro-Spec shock kit may be one of the more expensive options on the market, but only by a small amount, and for the attention to detail, added performance, and durability, they're worth the price! With unique features that change the game, the Pro-Spec kit alongside the PRO-2 SCT is an exciting next step in the evolution of Pro-Line's race program" Erich Reichert
