Key FeaturesHard-anodized aluminumBall bearing pivot gauge for optimum precisionLaser-etched determining scaleFor all racers: 1/5- to 1/10-scaleOverviewHere is an inventive new way for 1/5, 1/8 and 1/10 racers to practically remove framework "tweak" by specifically matching the length and damping rate of shocks. To set length, racers connect the shocks to the matching device and use the easy to read gauge to change length. To check lengths are equivalent all they need to do is make certain the gauge at the bottom of the device is centered. The coordinating gauge swinging in the direction of the "weaker" shock during compression will certainly show any difference in dampening rate. The Shock Matching Device is machined from anodized aluminum with a laser-etched determining scale on the face. The rotating gauge on the bottom of the device is ball bearing supported for optimum accuracy.
