The Monroe® Sensa-Trac® passenger car shock absorber with PSD (position sensitive damping) and the Safe Tech™ system combines our exclusive precision tapered grooves in the pressure tube with application engineered valving and Fluon banded piston to improve the ride, handling, and safety characteristics of the vehicle.

These features allow the Monroe Sensa-Trac passenger car shock absorber to adjust more rapidly to changing road and weight conditions than any other available shock absorber.

The result: enhanced control with uncompromised ride comfort.

• All Weather Fluid: Contains special modifiers to reduce friction and ensure smooth rod reaction.
• Full Displaced Valving: Tuned specifically for each application, this valving automatically adjusts to road extremes to provide consistency and ride comfort.
• 1-3/16" Bore: Larger bore than most shocks to provide more efficient and consistent control.
• Fluon Banded Piston: Works with the existing groove tube technology to enhance responsiveness to changing road conditions.
• Unique Groove Tube - PSD: Precision tapered grooves in the pressure tube perform like an additional stage of valving for optimum ride tuning.
• Nitrogen Gas Charged: For improved ride and handling, helps maintain tire to road contact by reducing aeration.
• 1/2" Diameter Piston Rod: Nitrocarburized rod* for long service life.
• Special Seal: "Self-lubricating" fluid seal designed to retain gas without excessive wear or friction.

The Monroe® Gas-Magnum® truck shock absorber is designed for mid to full size, hard working pick-up trucks and vans. These units provide firm control without a harsh ride. With up to twice the fluid capacity of standard 1" bore shocks, Monroe Gas-Magnum truck shocks work more efficiently with less effort.

• All Weather Fluid: Contains special modifiers to reduce friction and ensure smooth rod reaction.
• Full Displaced Valving: Better valving range on both the compression and extension cycles of the unit for a smooth comfortable ride.
• Sintered Iron Piston: Stronger than traditional metals, enhances durability for longer service life.
• Nitrogen Gas Charged: For improved ride and handling, helps maintain tire to road contact by reducing aeration.
• 2" Reserve Tube: More fluid for more consistent performance.
• 1-3/8" Bore: Lower operating pressure than standard 1" bore units.
• 5/8" Piston Rod: Heavy-duty nitrocarburized rod* for long service life.
• Special Seal: "Self-lubricating" fluid seal designed to retain gas without excessive wear or friction.
