Shocks 30 9436 30 Series 4 Way Adjustable Steel Body Mono-Tube Shock - 9 in. Stroke

Motor State Distributing has set the pace for high-performance automotive components for racing street and off-road use. To meet the demands of oval track racing KONI has chosen the Mono-tube gas charged design. This technology provides no fade valving and enables mounting of the shock absorber upside-down lowering the unsprung weight of the vehicle. Key features include a large 46mm diameter piston velocity sensitive; Lightweight single wall body / fewer internal parts; Consistent no fade valving / separate gas chamber; New low gas pressure for better driver feel. Some other manufacturers place a plastic bag filled with gas inside a hydraulic twin tube shock absorber as a means of preventing aeration or free stroke when the shock absorber is mounted upside down. In theory this is logical thinking; however in practice the plastic bags usually fail resulting in aeration and reduced performance. The plastic bags are not heat resistant and float within the shock absorber. The bags fail prematurely because of the abrasions received as it floats within the cylinder and the high operating temperatures experienced in oval track racing. When mounting a shock absorber upside-down the only shock absorber design that will not fail under the extreme conditions of oval track racing is the Mono-tube design. Lacking the engineering and manufacturing sophistications of KONI other suppliers offer the gas cell or plastic bag design. Features -30 Series 4 Way Adjustable Steel Body Mono-Tube Shock - 9 in.
