What is the purpose of the gas charge in this shock absorber?

The gas charge helps to keep the oil and gas separated within the shock absorber. This prevents foaming and aeration of the oil, which can lead to inconsistent damping performance, especially under heavy use.

Does this shock absorber come with all the necessary installation hardware?

Yes, this Superlift Shadow Shock Absorber includes all the bushings and sleeves needed for installation. It features a stem upper mount and a clevis lower mount.

How many shock absorbers are included with this part number?

This part number (89100) is for a single Superlift Shadow Shock Absorber. If you need to replace both front or rear shocks, you will need to order two units.

This shock absorber is designed to fit a range of popular Chevrolet and GMC trucks and SUVs, including models like the Chevrolet Silverado 1500 and GMC Yukon.

The twin-tube construction allows for ample oil capacity, helping to keep the shock cool and prevent fade.
