Axles
Upgrading your axles is one of the highest-impact modifications for trucks and off-road vehicles that regularly see hard launches, deep mud, rock crawling, or towing at the limits. Aftermarket axle shafts are manufactured from higher-grade steel than OEM units, delivering greater torsional strength and resistance to fatigue failures that stock shafts cannot handle under sustained abuse. Popular Upgrades Chromoly front and rear axle shafts are the go-to upgrade for lifted trucks and Jeep builds running larger tires with increased leverage on the driveline. Locking differentials paired with upgraded axles make a complete traction system for serious off-road builds. Heavy-duty CV axles for both front-wheel-drive and all-wheel-drive platforms handle the added stress of lowered suspension geometry and high-horsepower applications. When should I upgrade my axle shafts? Upgrade your axle shafts when adding larger tires, significantly increasing engine power, installing a locking differenti...
