This is a Hard Anodized Pivot Ball & Rod End Set for Slash 2WD. A major problem with the stock Slash 2WD suspension is the excessively tight stock rod ends and heavy steel pivot balls that prevent the suspension and steering components from moving freely. Pro-Line has solved this problem with all new Hard Anodized Lightweight Aluminum Pivot Balls and properly sized Pro-Line Rod Ends for a buttery-smooth suspension only found on high-end race trucks. The PRO-2 Hard Anodized Pivot Ball & Rod End Set will allow your truck to react quicker and be more planted through the corners. Upgrade your Slash 2WD today with Pro-Line’s PRO-2 upgrades!
