New shock absorber and suspension arms are now available for C-Series Backhoe Loaders to reduce suspension travel during roading or traveling through rough terrain. The 150-1550 Shock Absorbers have stiffer damping which stops the seat from bottoming or topping out, especially when height and weight adjusters are adjusted properly. The new 150-1549 Arm Assembly is stronger and will handle greater loads from the shock absorber. The new shock absorber and lift arm must be installed together.
