【Measurement】Hole center to center: 240mm (9.45 inch), 250mm (9.84 inch), 260mm (10.24 inch), 270mm (10.63inch), Mounting hole diameter: 0.4"(10mm),spring dia:0.43"(11mm) 【Precise damping control】Dual-loop independent adjustment for compression and rebound, zero roll during cornering, no jolts on gravel roads. 【Heat resistance attenuation performance:】Nitrogen filling + heat dissipation fin design. The performance does not deteriorate even after continuous bending for 1 hour. 【Adaptation to all scenarios】 Low-speed valve: Absorbs fine vibrations and shocks; Medium-speed valve: Reduces side roll during curves; High-speed valve: Absorbs jumping impacts 【Material】Aviation aluminum barrel body, diamond-coated piston rod Product Description SENBEDER RACING 980LB Rear Shock Absorber, 240mm/250mm/260mm/270mm Shock Absorber Suspension Spring Sensa-Trac Load for SDG SSR Pitster Lifan 110cc 125cc 140cc 200cc 250cc Pit Dirt Bike ATV
