Axiom Supply Shock Extension Kit for 1999–2006 Chevy/GMC Silverado/Sierra 1500 4WD (6-Lug)

Description

The Axiom Supply Shock Extension Kit is engineered to correctly extend the travel range of the factory front shocks on your 1999–2006 Chevrolet Silverado or GMC Sierra 1500 4WD. Designed specifically for 6-lug half-ton torsion-bar trucks, this kit safely adds up to 2 inches of effective shock length to accommodate leveled suspension setups. Precision-machined and built from durable materials, these extensions help maintain factory-like ride quality while preventing premature shock over-extension.

This system works best when paired with aftermarket upper control arms and OE or OE-equivalent shocks. Installing shock spacers on extended-length aftermarket shocks can cause damage, so Axiom Supply ensures proper fitment and reliability by engineering the kit specifically around factory geometry. Whether your truck is used for daily driving, towing, job-site work, or mild off-road use, this extension kit helps improve front-end performance and maintain consistent suspension operation.
