This is a pair of Pro-Line Rear Pro-Spec Shocks (kit form). The next generation of Pro-Line Shock Technology has arrived: Pro-Line Pro-Spec Shocks!  Every last detail has been refined to give you the best performing and best looking Shocks ever made. The Pro-Spec Shocks are a 12mm Big Bore design with a Single Low Friction X-Ring Seal. The Pistons and Shaft Guides are made from Silky Smooth White Delrin for Low Stiction and the 3.5mm thick Shock Shaft is Hard Chrome Coated, just like full scale racing shocks.

The Pro-Spec Shocks feature an easy access Bleeder Cap Screw for consistent shock builds every time. Each pair of Pro-Spec Shocks includes 3 different piston options (1.4, 1.6 & 1.8) and a blank piston for drilling to a custom size. Custom Shock Tightening Tools and optional shock limiters are also included. Pro-Line’s new Pro-Spec Shocks come in kit form with build instructions, so you can build the shocks exactly how you want. Optional Pro-Spec Springs are available separately. Upper and lower shock pivot balls are included so you can fit a wider range of vehicles right out of the box.

Radio Controlled Car Action - Test Bench: Pro-Spec Shocks

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
