Summary: The Rancho RS9000XL series delivers industry-leading versatility for the 1989-1991 Isuzu Trooper II 4WD. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow drivers to instantly tune their damping profiles to match specific terrain or load requirements. Whether you are seeking a soft ride for highway commuting or a firm setting for off-road stability, this Tier 2 adjustable shock provides the customized control necessary for classic 4WD applications. Engineered to accommodate up to a 1-inch front lift, they ensure optimal suspension travel and ride quality for leveled or mildly lifted setups.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine distinct levels of damping force to ensure the driver can switch between street comfort and off-road control.
• Large Diameter Shock Body: A 2.75-inch heavy-duty body provides increased fluid capacity to ensure cooler operation and reduced fade during strenuous use.
• Nitrogen Gas Charged: High-pressure gas integration provides a barrier against oil foaming to ensure consistent performance under rapid cycling.
• Protective Boot: A heavy-duty red polyvinyl bellows provides a physical shield for the piston rod to ensure long-term seal integrity against trail debris.
