Frequently Asked Questions

Will these shocks lift my GMC Sierra 3500HD?
No, these shocks do not create lift. They are specifically configured for vehicles that already have 5 to 6 inches of rear lift installed.

Are these shocks sold as a pair?
Yes, based on the SKU (2xRS55383), this product includes a pair of two rear shocks.

What is the benefit of the twin-tube design?
The twin-tube design is highly durable for off-road use; if the outer tube is dented, the inner piston tube remains unaffected, ensuring the shock continues to function.
