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.

Competition Engineering Rod Ends
Competition Engineering rod ends are available in a number of sizes, in both right-hand and left-hand threads, and all come with jam nuts. Their all-steel bodies are available in low-carbon, chromoly, or forged steel. Competition Engineering highly recommends that you use chromoly rod ends exclusively with their 4-link and ladder-bar suspension kits, with polyurethane-lined types reserved for street applications with ladder bars. Forged-steel types are not recommended for the front points of 3 or 4-link suspensions. Their Magnum series chromoly rod ends are the best choice for ladder bar and 4-link applications. They are self-lubricating and self-sealing with increased thickness for greater tensile strength--perfect for demanding motorsports applications. When loaded, Magnum rod ends create metal-to-metal contact for unsurpassed strength, yet when unloaded, the Rilsan AZM30-injected liner will not rattle or squeak like standard 2 or 3-piece rod ends.
