Each shock is custom tuned to match the suspension geometry of the F250 and F350 4WD, ensuring consistent ride quality and precise damping control. The 2.5 inch shock bodies provide more oil capacity, helping maintain smooth operation and reducing heat buildup during prolonged towing or off-road driving. External reservoirs increase fluid volume and enhance cooling, ensuring stable performance even under punishing conditions. These shocks are fully rebuildable and serviceable, making them a long-term investment in your truck’s suspension system. Extensive lab and real-world testing ensure they deliver the right damping curves for work, towing, and daily driving.
