The Maxtrac Suspension 947240VRA is a complete front and rear shock absorber kit from the Vulcan Series, engineered for 4-inch lifted applications on trucks equipped with factory rear air ride suspension. This box kit delivers a purpose-matched damping solution for lifted trucks, pairing precisely calibrated front and rear reservoir shocks in a single package.

Vulcan Series Reservoir Shock Technology:

• Monotube design with high-pressure nitrogen charging and an internal floating piston (IFP) for consistent, fade-free damping performance
• External reservoir provides increased oil and gas volume capacity for enhanced heat dissipation, preventing overheating under demanding conditions
• Durable aluminum body shields internal components and resists corrosion for long-term reliability
• Designed for 4" lift kits on factory rear air ride models — compatible with the OE air suspension system
• Bolt-on installation with included hardware for straightforward fitment

What's Included:

• Front Vulcan Series reservoir shock(s)
• Rear Vulcan Series reservoir shock(s)
• Installation hardware

Important Notes: This kit is designed to be used in conjunction with a 4-inch lift kit on rear air ride models. Maxtrac Suspension does not recommend the use of wheels wider than 9 inches or wheels with less than 4.5 inches of backspacing, as doing so will void the manufacturer warranty.

Backed by Maxtrac Suspension's 3-year limited warranty against defects in materials and workmanship for the original purchaser.
