Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically valved and sized to accommodate GMC Sierra 2500HD/3500HD models that have already been modified with a 5″ to 6″ rear lift kit.

What is the benefit of the twin-tube design on this model?
The twin-tube design is highly durable; if the outer body is dented by a rock or debris, the inner cylinder remains unaffected, ensuring the shock continues to function properly in harsh environments.

Are these shocks sold as a pair?
Yes, based on the SKU configuration, this product includes two (2) rear shocks for a complete axle installation.
