{"title":"Radflo Off-Road Air Shocks","description":"\u003cp\u003eRadflo Off-Road Air Shocks provide a lightweight and highly tunable suspension solution for rock crawlers, rock bouncers, trail rigs, Ultra4 cars, and custom tube chassis vehicles. Unlike traditional coilover suspension systems that rely on steel springs, air shocks use compressed nitrogen and suspension oil to support vehicle weight and control suspension movement. This eliminates the need for external springs while reducing overall suspension weight and simplifying packaging in tight chassis designs. Available in multiple travel lengths and configurations, air shocks remain a popular choice for builders seeking maximum articulation, simplicity, and adjustability.\u003c\/p\u003e\n\u003cp\u003eCommonly used on custom off-road suspension systems, Radflo air shocks allow ride height, spring rate characteristics, and damping performance to be tuned through nitrogen pressure and internal valving adjustments. Their compact design makes them ideal for rock crawler suspension, trail buggy suspension, and lightweight off-road racing applications where suspension packaging can be challenging. Built with race-proven components and fully rebuildable construction, Radflo air shocks deliver reliable performance, excellent articulation, and consistent control across rocks, trails, climbs, and technical terrain while maintaining the durability required for demanding off-road use.\u003cbr\u003e\u003c\/p\u003e","products":[{"product_id":"radflo-2-5-air-shock-1-5-8-shaft","title":"Radflo 2.5 Air Shock - 1-5\/8″ Shaft","description":"\u003cp\u003eThe Radflo 2.5 Air Shock with a massive 1-5\/8″ (1.625″) shaft is built for lightweight off-road vehicles that demand strength, simplicity, and tunability and is available in 8″, 10\", 12\", 14\", 16\", or 18\" travel lengths.
