VEMCO VX4 Four-Wheel-Drive Conversion Brochure - One Ton Chevy Vans

This is a vintage sales brochure from VEMCO (Vehicle Engineering & Manufacturing Company, Inc.) of Fort Wayne, Indiana, advertising the VX4 four-wheel-drive conversion system for one-ton Chevrolet vans. The cover features an exploded illustration of the complete drivetrain layout, including front and rear axles, transfer case, and prop shafts. The brochure highlights six selling points: unchanged vehicle height (yielding a lower center of gravity, less body roll, and better crosswind stability than conventional 4WD conversions), an independent coil spring front suspension for improved ride and handling, improved front axle and transfer case ground clearance for off-road use, improved traction via a new inter-axle differential balancing torque between front and rear axles (a full-time 4WD system), and lightweight construction using a Spicer front gear box and V-axle transfer case that keeps added weight within 350 pounds. It also notes over 15 years of design and development, stating that major drive line components—wheel end gear boxes, wheel end assemblies, transfer case, and prop shafts—are manufactured by Dana Corporation.
