{"product_id":"radflo-2-5-non-coil-bump-stops","title":"Radflo 2.5 Hydraulic Bump Stop - 1-5\/8” Shaft","description":"\u003cp\u003eThe Radflo Off-Road 2.5 Hydraulic Bump Stop is engineered to control hard suspension. Using velocity sensitive damping, it acts as a secondary shock during the final inches of compression; this hydraulic bump stop progressively increases damping resistance to absorb impact energy while protecting both the vehicle and occupants from damaging stress loads.\u003c\/p\u003e\n\u003cp\u003eAt the core is Radflo’s exclusive Freeflo® Racing Piston, combined with a massive 1.25\" chrome plated alloy steel shaft, machined bronze rod guide, and multi-direction sealing system, this bump stop is built to survive the harshest off-road environments. Stroke options of 2\", 3\", or 4\" allow proper integration into a wide range of suspension designs and mounting constraints. Every unit is fully rebuildable, serviceable, and tunable, ensuring long term performance and virtually unlimited service
