Camburg KINETIK Series 2.5 x 3.75 Bump Stop (Bolt-on Flat Top > Striker)

With over 25 years of off-road use and racing experience, Camburg set out to engineer a hydraulic bump stop that exceeded the demands of our suspension kits and race trucks. After years of design, development, and extreme testing on our championship-winning race truck 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 bolt-on flat top striker bump stops are specifically designed and tuned for custom front and rear applications. Hydraulic bump stops significantly 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, allowing tuning based on driving style, vehicle setup, and use. 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. Bodies are finished in black Cerakote® for superior abrasion, corrosion, and chemical resistance. CNC-machined 6061-T6 aluminum components are anodized Camburg red and feature four bolt upper mounting to securely retain the bump stop in the mounting can, with an integrated Schrader cap for added protection and sealing. Internally, aerospace-grade seals, custom-molded 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 durability in extreme off-road conditions. While we didn’t invent hydraulic bump stops, we refined them to meet the performance standards expected from Camburg suspension systems and our KINETIK race program.  Read Less
