Bypass1 is a shock kit with pistons created by MIP’s design team that change how all RC shocks work. Months of dyno and track testing of dozens of piston and valve designs have culminated in our Bypass1 configuration. Custom color coded valves, octagon shaped pistons and special configured stop washers all combine to create bypass shock technology only used on full scale vehicles. The name, Bypass1 identifies how MIP has applied our bypass technology into RC shocks compression stroke. MIP Bypass1 incorporates the use of standard shock oils that allow users to keep their same set-ups. MIP Bypass1 valves combined with MIP’s unique piston design virtually eliminate hivelocity packing (hydraulic locking) caused by standard RC shocks with traditional orifice holes design. MIP Bypass1 pistons use color coded valves with corresponding thicknesses to make valve selection quick and easy. How do they work? Traditional RC shock pistons are designed with orifice holes to meter compression and rebound dampening 50/50. Orifice holes are susceptible to packing (hydraulic lock) at higher shaft speeds witch limit traction and handling. Some companies have tried to make pistons which change the compressive and rebound dampening but have always overlooked the issue of packing. Bypass1 meters the oil around the piston to control the rebound dampening. As the piston moves into a compressive stroke; the oil moves through the bypass orifices and into the valves flexing the valves; which results in bypass. This is in addition to the oil flowing around the piston. go to www.realshocks.com for more info!
