Torque Heavy Duty Shock Absorber Kit
The Torque set is designed for extensive truck suspension systems, including CUSH, Hendrickson, Ridewell, SAF Holland, Trailmobile, and Meritor. Each absorber pairs with Gabriel 85000 and Monroe 65416 equivalents, providing a balanced combination of extended length (17.22″) and a moderate stroke (5.76″). Dust seal and recoil cutoff features help protect internal components from road grime. This multi-brand compatibility supports fleets using varied air-ride or leaf-spring configurations, with a focus on reliability in heavy-duty applications.
Key specs include an extended length of 17.22″, collapsed length of 11.46″, and a bore of 1-5/8″. Rebound and compression ratings (1019 lb. rebound, 219 lb compression) indicate a stiffer ride suitable for heavy loads. The set weighs about 6 lbs per unit, making installation straightforward for compatible trucks and trailer suspensions. The product notes also reference interchanges with Gabriel 85000, Monroe 65416, Freightliner 16-14759-00, and various Meritor and Wabash models, which broadens applicability across fleets.
Gabriel 85000 Fleetline Rear Shock Absorber
Gabriel’s Fleetline line targets heavy-duty trailer suspensions, including Hendrickson Intraax/Vantraax and related air-ride systems. The unit lists an extended length of 17.28″ and a collapsed length of 11.5″, with a stroke around 5.78″ and an interchangeable part catalog that includes OEM numbers like A-20002 and 665788. Upper and lower mount codes ES36 align with common trailer chassis, supporting quick swaps in a fleet that relies on multiple brands. The wide compatibility helps simplify replacement decisions for mixed fleets.
The product supports a wide array of trailer builds—from Freightliner and Meritor to Trailmobile and SAF Holland—reducing downtime for maintenance. The listing highlights a long interchange ledger, including M85000 and AMS650419 variants, indicating broad cross-compatibility with older and newer shock models. Users should verify mount codes on their chassis to ensure a precise fit before purchase.
Mytee Products 4 Pack Heavy Duty Shocks
Mytee Products supplies a four-pack of heavy-duty shock absorbers designed for semi-trucks like International 4700 and Freightliner Argosy, with compatibility extending to Meritor, Haldex, and Gabriel systems. The shocks are aligned with OEM specifications and fit several Sterlin/Acterra, Ford, and Automann models. The extended length measures 22-3/4″ and a collapsed length of 14-1/2″, with a bore of 1-5/8″ and a stroke of 8-1/4″. Installation guidance emphasizes proper vehicle support and torqueing at ride height to ensure secure mounting, which is essential for safety and performance on long hauls.
Cross-brand compatibility supports mixed fleets, enhancing stocking efficiency for repair shops and owner-operators. The kit’s design aims to deliver improved control and ride quality under heavy payloads, helping to stabilize trailers and reduce sway. Prospective buyers should confirm mounting hardware compatibility and any required end-murterm replacements to ensure lasting performance in a demanding freight environment.
Gabriel 85642 Fleetline Rear Shock Absorber
Gabriel’s 85642 Fleetline is engineered for heavy-duty Internationals and similar Class 8 configurations. It covers several 17-24 International LT625, LoneStar, MV607, ProStar variants, and RH613 models. Specifications list an 8″ stroke, 22.52″ extended length, and 14.52″ collapsed length, with mount codes ES177 and ES90. The extensive interchanges include numbers like 65549, 925169, and 6127666C1, indicating broad compatibility across a wide range of chassis and configurations. The design focuses on durable performance under heavy loads and long miles.
For fleet managers, this shock offers a balance between durability and compatibility with major OEMs. Potential buyers should verify the specific International or ProStar model year and axle configuration to ensure precise fitment. The 360° mount options contribute to robust attachment, helping resist end-mount fatigue over time.
Monroe Gas-Magnum 34504 Suspension Shock
The Monroe Gas-Magnum 34504 is designed for trucks and vans requiring dependable ride stability. It features full-displaced valving on compression cycles to deliver controlled ride characteristics and handling for off-road or heavy-load conditions. The nitrocarburized rod and sintered iron piston enhance durability, while a self-lubricating fluid seal reduces friction and wear. This makes it a practical choice for fleets seeking consistent performance in extreme temperatures and variable road conditions. The product emphasizes durability and long service life, with design elements aimed at reducing wear over time.
When evaluating Monroe options, consider ride height, mounting compatibility, and the need for improved highway stability versus off-road capability. The shock’s design targets high-mileage routes, and its materials are chosen to withstand tough fleet duties. Always verify the upper and lower mount codes against your chassis configuration to ensure an exact match.
Buying Guide: Key Purchase Considerations And Comparisons
Purpose and load: Identify whether you primarily drive long-haul routes, off-road conditions, or heavy freight. Heavy-duty shocks should balance load-bearing capacity with road feedback to minimize passenger and cargo movement.
Fitment compatibility: Cross-brand compatibility can simplify inventory, but always verify specific model years, axle configurations, and mount codes (upper and lower) before purchasing. Record any OEM part numbers listed in the product details for a precise match.
Stroke and length: Longer extended lengths generally improve wheel travel and ride stability under load, but ground clearance and mounting geometry must align with your chassis. Note collapsed length to ensure enough clearance when the suspension is compressed.
Construction and durability: Look for robust rod materials (e.g., nitrocarburized rods), bushings, seals, and degreased interiors designed to withstand temperature fluctuations and road grime. End mounts and eye rings should offer high shear strength to resist fatigue during heavy use.
Maintenance and replacement: Consider the availability of replacement parts and the ease of installation. Shocks that share common interchange part numbers across brands can simplify stocking and repairs for mixed fleets.
Cost vs. value: The initial cost should be weighed against service life, maintenance intervals, and potential downtime. For fleets, it’s often economical to select shocks with proven durability and wide OEM compatibility to minimize maintenance headaches.
