ADS Racing Shocks 3.0 MBR Multiple Bypass Ring Internal Bypass Shock (MBR IBP) Multi-Stage Bypass Ring What is MBR technology? Multi-Stage Bypass Ring, a true multi-stage bypass system, each zone is independently adjustable internally via a positive stop helix system. What does this mean? Flow and lots of it, (similar flow rates to a 7 tube External bypass on 16" stroke variations). Internal free bleed ports allow the tuner to maximize the damping curve, for each vehicle's needs. True top out zone provides mechanical as well as hydraulic damping, preventing damage from fully extending the shock in harsh conditions (as always limit straps are recommended for racing and severe use) 4 -way adjustable reservoir allows both high and low speed adjustment independently on compression and rebound events Dual Hose system creates a true recirculating fluid path to the reservoir for maximum fluid cooling. Internal diverters ensure fluid flow encompasses the entire shock body promoting even further cooling performance. Each unit is vacuum bled and features full synthetic fluid, nearly eliminating fade and increasing product life. capacity 2.5" reservoirs increase Large fluid capacity to aid in cooling, high temperature seals prevent blow by increasing performance over a large temperature range, threaded end caps eliminate contamination from outside sources. 3 stage urethane seal package offers unmatched sealing, for the coldest cold snow ridden trails to the scorching deserts and beyond.
