Rancho RS90000XL 2.5-4″ Front Lift Shocks for 1969-1986 GMC K2500 4WD

Part Number: RS999001

Summary: The Rancho RS90000XL series provides unparalleled ride control for the GMC K2500, featuring a globally recognized 9-position manual adjustment knob. This Tier 2 adjustable system allows drivers to instantly tune the damping profile to accommodate varying loads, from daily street driving to heavy-duty towing. Engineered for vehicles with 2.5 to 4 inches of front lift, these shocks solve the compromise between comfort and control by putting the final tuning parameters in the hands of the user.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping resistance to ensure the perfect ride quality for any terrain or payload.
• Large Shock Body: A heavy-duty 2.75-inch diameter reserve tube provides increased oil capacity to ensure consistent performance and reduced fade during high-stress operation.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a barrier between the oil and air to ensure zero aeration and immediate response.
• Protective Boot: A durable liquid metallic finish and included red dust boot provide maximum protection for the piston rod to ensure long-term seal integrity.
