Product Details

This premium front shock spacer kit from Axiom Supply is designed to fit a range of GM heavy duty trucks and SUVs. It fits Chevrolet Silverado 2500 HD and 3500 and GMC Sierra 2500 HD and 3500 from 11-26, as well as Hummer H2 from 2002 through 2009 and select Avalanche, Suburban XL, Yukon XL, and 1500HD eight lug trucks.

The kit is engineered to extend the effective length of the factory front shocks when the suspension is leveled or mildly lifted. This helps maintain proper shock travel and ride quality instead of overextending the OE shocks.

Important Fitment Note: The shock spacer kit must be installed only on OE shocks or OE equivalent shocks. Installing shock spacers on plus length shocks may result in premature wear or catastrophic component failure.

Refer to the shock extension instructions for full details. This kit is intended to be used in conjunction with aftermarket upper control arms.

Features and Benefits:

  • Helps maintain factory like ride quality when paired with proper supporting components
  • Extends effective shock length to work correctly with leveled front suspension
  • Premium black powder coated finish for long lasting corrosion resistance
  • Durable construction designed to complement heavy duty suspension setups

The Axiom Supply shock extension kit provides a safe and straightforward way to retain your factory front shocks on leveled 11-26 GM HD trucks.

By spacing the lower mount, the kit restores proper shock position and travel range after the front of the truck has been raised, helping prevent overextension and harsh topping out.

Precisely engineered and machined for strength and durability, these spacers offer a reliable upgrade over improvised or low quality hardware.

When paired with a quality aftermarket upper control arm kit and compatible shocks, this system supports a level stance and stable ride without sacrificing comfort or control.

Includes:

  • One front shock extension spacer kit
  • The Axiom no nonsense lifetime warranty to the original purchaser

Our suspension and steering components are warrantied for life against manufacturer defects, premature wear, or breakage. If the part ever lets you down, we will make it right.
