Camburg set out to design a hydraulic bump stop that significantly improved performance for our suspension kits and race trucks. After years of development and extreme testing on our championship-winning race truck and off-road fleet, we’re proud to introduce the 2026 Camburg KINETIK Series 2.5 bump stops. The Camburg KINETIK Series 2.5 x 2.5 slapper bump stops are specifically designed and tuned for our stock-length and long-travel lower control arms using our billet slapper arm design, while remaining suitable for custom applications. Hydraulic bump stops dramatically improve bottoming control in hard g-out situations, allowing your shocks to focus on handling while transferring bottoming forces into a stronger, chassis-mounted component. Nitrogen pressure is adjustable from 50–250 psi, allowing bottoming control to be tuned to your driving style and vehicle setup. The 2.5-inch diameter body increases oil and nitrogen volume for improved damping consistency, reduced operating temperatures, and enhanced tunability. Heat-treated cylinders increase strength while reducing internal friction, improving seal and fluid longevity. The bump stop body is finished in black Cerakote® for superior abrasion, corrosion, and chemical resistance. CNC-machined 6061 aluminum upper and lower eyelets are anodized Camburg red and feature a pocketed design to reduce weight. FK PTFE-lined spherical bearings with custom-molded rubber seals and 17-4 stainless spacers provide durability, protection from contaminants, and ease of installation. Internally, aerospace-grade seals, custom travel indicators, Type III hard-anodized tapered-port pistons, and a 1.625-inch induction-hardened, hard-chrome shaft deliver consistent damping, reduced friction, and long-term reliability in extreme off-road conditions. While we didn’t invent hydraulic bump stops, we refined them to meet the performance standards expected from Camburg slapper suspension kits and our KINETIK race trucks.
