PURE Racing TRX Rear Shock – Surron Ultra Bee | 500 lb Trail

Upgrade the rear suspension on your Surron Ultra Bee with the PURE Racing TRX Rear Shock, configured with the Trail valve tune and 500 lb coil spring for controlled, supportive, and comfortable performance across trails, enduro riding, technical terrain, and general off-road use. The TRX uses a dual parallel oil damping system with independently adjustable compression and rebound, giving riders precise control over rear suspension behavior. Both compression and rebound offer 19 stages of adjustment, making it easy to fine-tune the shock for terrain, rider preference, and riding style. Internally, PURE's 3D-printed Waffle Piston technology and precision-honed cylinders are engineered to improve oil flow, damping consistency, traction, and suspension response. The structural components are 5-axis CNC-machined, while the linkage plate design is optimized for rigidity, fatigue resistance, and strength. The 500 lb Trail configuration is also PURE Racing's recommended rear-shock match for the TRAXION Trail 960N fork, creating a balanced front and rear suspension package for the Surron Ultra Bee.
