Pro Comp suspensions use world-class manufacturing processes and stringent quality control measures to deliver only the best possible products to their customers. This results in performance and reliability, no matter what obstacles are in your path. Big ticket items such as cast and CNC-machined knuckles and laser-cut, CNC-formed, robotically welded cross members are the foundation for many of these suspension kits, but little details such as brake line extensions, longer bump stops, and sway bar drop brackets are always included to provide the most complete suspension systems on the market. These details distinguish Pro Comp from their competitors and are critical for proper steering geometry and suspension performance. Detailed step-by-step illustrated instructions are included with every suspension kit to make installation as straightforward as possible. Pro Comp is so confident that you will love their products that they back over 260 kits with the Lift Shield 5 year / 60,000 mile power train warranty and all products are covered by the Pro Comp Promise Lifetime Warranty.
