The UpGrade RC Big Bore High Performance Front Shocks are designed to improve suspension performance, consistency, and control on the Losi Micro-B and Micro-T. Featuring an oversized big bore design with increased oil capacity, these shocks provide smoother damping and improved impact absorption in a compact package built specifically for these micro platforms. Engineered in the USA, the UPG-11028 front shocks are a performance-focused upgrade for drivers looking for more predictable suspension action, improved landings, and better overall chassis control. About the Big Bore Front Shocks Increased Damping Control The oversized shock bodies provide increased oil volume and improved oil flow for smoother, more consistent damping. The higher oil capacity also helps reduce damping fade during extended runs, keeping suspension response more predictable. Plush, Controlled Landings Balanced compression and rebound characteristics help the suspension absorb jumps and hard impacts while keeping the chassis more composed. This can improve traction, reduce chassis slap, and provide greater control over uneven terrain. Performance-Focused Construction Designed with tight tolerances and a durable big bore construction, these shocks are built to withstand repeated impacts while maintaining smooth suspension operation. Features ✔ Designed for Losi Micro-B and Micro-T✔ Big bore front shock design✔ Largest bore size available for these platforms✔ Increased shock oil capacity✔ Improved oil flow✔ Smooth, consistent damping performance✔ Helps reduce damping fade during extended runs✔ Balanced compression and rebound✔ Improved impact absorption✔ Plush landing characteristics✔ Improved suspension and chassis control✔ Engineered in the USA✔ Mounting hardware included Includes (2) UpGrade RC Big Bore High Performance Front Shocks (4) Mounting Bolts Needed to Complete Silicone Shock Oil Specifications Specification Details Brand UpGrade RC Part Number UPG-11028 Product Type Big Bore Front Shocks Extended Length 32.75mm (1.29") Eye-to-Eye Collapsed Length 24mm (0.95") Eye-to-Eye Shaft Diameter 1.5mm (0.06") Weight 1.42g (0.05oz) Quantity 2 Compatibility Compatible with: Losi Micro-B Losi Micro-T Notes These are front shocks.
