Competition Engineering Adjustable Drag Shocks
These Competition Engineering adjustable drag shocks offer a 3-way valving system to dial-in the extension/compression ratio needed for any track condition. The front shocks have three adjustable ratios of 90/10, 80/20, and 60/40. The ratios for the rear shocks are 70/30, 60/40, and 50/50. These numbers represent the percentage of force required to extend (first number) and compress (second number) the shock. By changing the settings on the front and rear shocks, you can dial-in the car to raise the front on initial launch for weight transfer, and then settle smoothly for a final charge to the finish line.
