The 300-MBR18-000 by ADS Racing Shocks represents a cutting-edge approach to suspension tuning, featuring Multi-Stage Bypass Ring (MBR) technology. This system allows for independent adjustment of each zone through a positive stop helix mechanism, ensuring optimal flow similar to 7-tube external bypass designs found in 16" stroke variations. The internal free bleed ports enable precise tuning of the damping curve tailored to specific vehicle applications.
This coilover shock is designed with a true top-out zone that combines mechanical and hydraulic damping, providing protection against shock damage during full extension in demanding conditions. While the design is robust, the use of limit straps is recommended for racing and extreme applications to further safeguard the shocks.
The 4-way adjustable reservoir allows for independent high and low-speed adjustments for both compression and rebound, enhancing the tuning capabilities for various driving scenarios. The dual hose system creates a genuine recirculating fluid path to the reservoir, which maximizes fluid cooling. Internal diverters ensure that fluid flows evenly across the entire shock body, significantly improving cooling efficiency.
Each shock undergoes a thorough vacuum bleeding process and is filled with full synthetic fluid to minimize fade and prolong service life. The large 2.5" reservoirs increase fluid capacity, aiding in cooling performance, while high-temperature seals prevent blow-by, ensuring reliable operation across a wide temperature range. Threaded end caps are included to keep contaminants out, enhancing the longevity of the shocks.
Additionally, the 3-stage urethane seal package offers superior sealing performance, making the 300-MBR18-000 suitable for extreme environments, from cold, snow-covered trails to scorching desert conditions.
