U.S.-stock and overseas-sourced items have different lead times. If this item must ship from Japan or another country, supplier processing, international transit and customs clearance can extend delivery. A shipping service transit estimate does not include supplier lead time. Contact RACECLUB for the current dispatch estimate before ordering time-sensitive or special-order parts.
For shipments crossing a border, customs duties, import taxes and carrier brokerage or handling fees may apply. Charges expressly collected at checkout are shown there; otherwise additional import charges may be payable by the recipient. Foreign manufacture alone does not mean your order will ship internationally. Confirm the shipping origin and any applicable import charges with us before ordering.
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.
