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.

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.
