Monroe Sensa-Trac Load Adjusting Shock Absorber (MPN: 58574)

Enhance ride quality and handling for towing and hauling applications.

The Monroe Sensa-Trac load adjusting shock absorber is engineered to improve vehicle ride, handling, and safety characteristics. Featuring position sensitive damping (PSD) technology, these shock absorbers utilize precision tapered grooves in the pressure tube combined with application-specific valving to adapt to varying road conditions. This design ensures consistent performance, making it suitable for light trucks that frequently carry loads or tow trailers.

Constructed with a heavy gauge calibrated coil spring, the Sensa-Trac shock absorbers provide enhanced control and comfort without increasing ride harshness. The nitrogen gas charged design helps maintain optimal tire-to-road contact by reducing aeration, which is crucial for stability during towing and hauling. Additionally, the self-lubricating fluid seal is designed to retain gas effectively, minimizing wear and friction over time.

These shock absorbers are equipped with features such as all-weather fluid to reduce friction, full displaced valving for consistent ride quality, and a Fluon banded piston for improved durability. With a capacity to assist in maintaining ride height under additional weight, the Monroe Sensa-Trac shock absorbers are a reliable choice for those needing enhanced performance in variable load conditions.
