KINETIK Series 2.5 x 3.75 Slapper Bump Stop (Eyelet > Eyelet

With more than 25 years of off-road use and racing experience, Camburg set out to design a hydraulic bump stop that raised the bar for performance and durability. After years of development and extreme testing on our championship-winning race trucks and off-road fleet, we’re proud to introduce the 2026 KINETIK Series 2.5 bump stops. The KINETIK Series 2.5 x 3.75 slapper bump stops are specifically designed and tuned for a slapper arm design, while remaining adaptable for custom applications. Hydraulic bump stops dramatically improve bottoming control in hard g-out situations, allowing primary shocks to manage handling while transferring bottoming loads into a stronger chassis-mounted component. Nitrogen pressure is adjustable from 50–250 psi, enabling precise tuning based on vehicle setup and driving style. The 2.5-inch diameter body increases oil and nitrogen volume for improved damping consistency, reduced operating temperatures, and enhanced tunability. Heat-treated cylinders provide increased strength and reduced internal friction for longer seal and fluid life. Each body is finished in black Cerakote® for superior abrasion, corrosion, and chemical resistance. CNC-machined 6061 aluminum 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 ensure 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 the harshest off-road conditions. While we didn’t invent hydraulic bump stops, we engineered them to meet the performance, durability, and quality expected from Camburg and our KINETIK race program.
