Tenneco has announced it will introduce a line of U.S.-manufactured, gas-charged shock absorbers as its main product offering for the North American commercial vehicle market. The all-black Monroe Magnum shock absorbers, engineered to help fleets and other users reduce cost per mile through durability, improved vehicle control and increased driver comfort and satisfaction, were introduced in conjunction with Heavy Duty Aftermarket Week (HDAW) in Las Vegas.
Commercially available April 1, 2018, Monroe Magnum shock absorbers will combine a range of advanced design and construction features engineered to address the increased demands of today’s hardworking, over-the-road tractors and trailers, municipal, emergency and other severe-use vehicles. Each shock will be covered by Monroe’s 90-day risk-free ride offer and technical and product application support, according to the company.
“The Monroe Magnum line has already become a leading choice of commercial vehicle fleets, municipal waste haulers, transit fleets and other customers throughout Europe,” says T.J. Fontana, director of sales, commercial vehicle, Tenneco North America Aftermarket business. “We’re pleased to bring this proven brand to the North American market with premium-quality Magnum products manufactured in our Paragould, Ark., facility.”
Quality and performance designs featured in Magnum shocks include a large-diameter nitrocarburized rod that provides improved compression control and side-load strength; PTFE-coated rod guide bearing that increases durability by minimizing friction between the rod and rod guide; robust hydraulic lock-out design that helps prevent over-extension of the suspension; larger diameter piston to provide greater tuning precision for each vehicle application; and Tenneco’s latest, advanced shouldered bushing design, where applicable, which helps prevent bushing extrusion and related concerns, according to the company.
New Monroe Magnum shocks also offer twice the pressure-tube thickness of many competing commercial vehicle shocks, the company says. Increased pressure tube thickness significantly reduces the chances of shock damage in extreme load and road conditions.
