Designed for rock crawlers, rock bouncers, trail rigs, Ultra4 cars, and custom off-road vehicles, this shock combines the tunability of a bypass shock with the simplicity of an integrated piggyback reservoir.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eUnlike standard coilover shocks, bypass shocks allow suspension damping to change throughout the shock stroke. This gives builders the ability to create a smoother ride over rough terrain while increasing control near full compression and extension. The result is improved traction, greater stability, and better overall suspension performance.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eThe piggyback reservoir eliminates the need for external reservoir hoses while still increasing oil capacity and cooling performance. This creates a cleaner installation and simplifies packaging in vehicles where space is limited. For builders looking to improve suspension performance without adding additional hose routing and mounting brackets, the Radflo 2.5 Piggyback Bypass Shock offers an excellent balance of performance, simplicity, and durability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncludes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e(1) Radflo 2.5 3-Tube Bypass Shock \u003c\/li\u003e\n\u003cli\u003e\n\u003cmeta charset=\"utf-8\"\u003ePiggyback Reservoir\u003c\/li\u003e\n\u003cli\u003eUniversal spherical bearings and mounting hardware\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cb\u003eAvailability Note:\u003c\/b\u003e \u003c\/span\u003eAs the #1 stocking warehouse for Radflo Performance Shocks, we maintain one of the largest inventories of Radflo coilovers and springs in the industry.
