Key specs include an extended length of 17.22 inches, collapsed length of 11.46 inches, and a stroke of 5.76 inches, with a bore of 1-5/8 inch. The kit emphasizes dust protection and recoil cutoff for durability under heavy trailer use. The included units provide a balance between load handling and ride consistency on tandem-axle configurations.
Gabriel 85000 Fleetline Heavy Duty Rear Shock Absorbers
Gabriel’s Fleetline line is presented as a direct replacement option for Hendrickson Intraax and Vantraax suspensions, among others. It lists a broad compatibility range with trailers and buses, including SAF Holland, Wabash, and Meritor suspensions. Specifications show an extended length of 17.28 inches and a collapsed length of 11.5 inches with a stroke around 5.78 inches. Interchange and OEM part numbers are provided to help verify compatibility. This option targets reliability in heavy-duty trailer applications where OEM matching is essential for proper mounting and performance.

This pack is designed for replace-in-kind upgrades on trailers requiring consistent damping across both axles, emphasizing durability and interchangeability among major OEMs.
Monroe Magnum RV 555003 Suspension Shock Absorber
Monroe’s Magnum RV model focuses on universal compatibility for recreational and utility trailer use. While the listing emphasizes fit verification via the Amazon Confirmed Fit bar, it is designed to support cross-country travel demands and rugged trailer duty. Buyers should confirm year, make, model, and trim to ensure a proper match. This option is suitable for RVs and light-to-medium-duty trailers where consistent damping enhances stability on uneven surfaces and during cornering.
Mytee Products 4 Pack Heavy Duty Shock Absorber For Semi Trucks
Mytee Products offers a four-pack of heavy-duty shocks designed for semi-truck trailers, with compatibility including Freightliner Argosy, International 4700, and several OEM-equivalent replacements.

The product notes emphasize OEM-equivalent specifications and a clear installation guidance to ensure correct mounting and torque at ride height. This option targets trailers requiring longer travel and higher damping forces for long-haul or heavy loads.
Buying Guide: Key Purchase Considerations
- Compatibility and fitment: Verify axle type (e.g., Hendrickson Intraax/Vantraax, Ridewell, SAF Holland) and mounting codes to avoid mismatch.
- Extended and collapsed length: Match the shocks to the existing travel of your trailer suspension to maintain proper ride height and damping.
- Stroke and bore: Ensure the stroke and bore sizes support your load and mounting geometry for adequate damping response.
- Durability features: Look for dust tubes, recoil cutoff, and corrosion resistance to withstand roadway conditions and salt spray common on American highways.
- Interchangeability: Some shocks list multiple OEM part numbers—this can simplify future replacements if your fleet uses mixed suspensions.
- Installation and torque: Follow torque specifications and ensure the trailer is supported during replacement to prevent injury and ensure correct eyelet mounting.
- Use-case considerations: RV and trailer applications may prioritize smoother ride over extreme load damping; commercial freight trailers may need higher damping forces for stability at speed.
- Warranty and support: Check manufacturer warranties and availability of replacement parts or compatible variants for ongoing maintenance.
