Mytee 4 Pack Heavy Duty Shock Absorber for Semi Trucks (B0DGY11763)
The Mytee Products kit is a 4-piece set designed as a direct replacement for several Peterbilt and Mack models, aligning with OEM specifications (e.g., 85067). Fitment notes cover compatibility with Haldex SA65495 and T680 2013-2022 variants, ensuring balanced damping across typical highway loads. Key technical details include a bore of 1-5/8 inches, an extended length of 30-1/2 inches, a collapsed length of 18-1/8 inches, and a stroke of 12-7/16 inches. Installation guidance emphasizes securely supporting the vehicle, removing old shocks, aligning mounts, and torquing hardware at normal ride height. This kit aims to deliver consistent control under variable cargo, improving ride stability and steering feel on rough roads. The four-pack option helps standardize maintenance across a fleet.
Mytee 4 Pack Heavy Duty Shock Absorber for Semi Trucks (B0DGXYSTN3)
This Mytee set focuses on Peterbilt-compatible variants with OEM-replacement part numbers like 8569 and SHOCK ABSORBER designations for Peterbilt 33, 335, 337, 357, 362, 365, and related series. The features highlight a broad compatibility map intended to simplify parts planning for fleets with mixed Peterbilt configurations. While the package includes multiple units, individual installation follows standard procedures: disconnect power, safely lift the vehicle, replace shocks, and re-torque to spec once ride height is restored. The arrangement supports consistent damping performance across several Peterbilt-based platforms and similar heavy-duty applications where reliable control is critical.
TORQUE 85000 Heavy Duty Shock Absorber (B09463T7Y3)
The TORQUE TR85000 shock absorber is designed for Hendrickson Intraax, Vantraax, CUSH, Ridewell, Trailmobile, SAF Holland, and related suspension families. Specifications include an extended length of 17.22 inches, collapsed length of 11.46 inches, and a bore of 1-5/8 inches, with a 5.76-inch stroke. Features such as a dust tube and recoil cutoff are noted, along with a maximum rebound and compression rating that supports heavy-duty handling. The unit is listed as a replacement for Gabriel 85000, Monroe 65416/65419, and multiple OEM-equivalent assemblies. This makes it a versatile option for various trailer and chassis configurations where reliable damping is needed to maintain stability under heavier payloads.
TORQUE 6 Pack 85000 Heavy Duty Shock Absorber (B0BQ99Q8SV)
This 6-pack TORQUE offering targets direct OEM replacements across multiple suspension brands, including CUSH, Hendrickson, Ridewell, SAF Holland, and Trailmobile Canada. Specs mirror the single-unit variant with an extended length around 17.22 inches, collapsed length near 11.46 inches, and a 1-5/8 inch bore. Its design emphasizes durability with features like a dust tube and recoil cutoff, plus a noted 1019-lb rebound and 219-lb compression rating. The package is positioned for fleets needing bulk stocking to minimize downtime and ensure consistent damping across mixed trailer and truck configurations, particularly for heavy-haul operations.
Mytee 4 Pack Heavy Duty Shock Absorber for Freightliner (B0DGXYY141)
The Mytee Freightliner-specific kit covers 2009-2025 models (114SD, 122SD, Cascadia, Columbia) and replaces OEM 85958. The unit aligns with OEM specs and includes clear installation instructions: support the vehicle, remove old shocks, mount and torque to ride-height specifications. The extended length (24-3/4 inches) and collapsed length (15-1/4 inches) with a 1-5/8 inch bore and a 9/12 inch stroke support a wide range of Freightliner suspensions. This package is tailored for operators seeking a standardized upgrade path across Freightliner-trimmed fleets.
Buying Guide: Shocks For Semi Trucks
When choosing shocks for semi trucks, consider these factors to ensure compatibility, performance, and value:
- Vehicle and suspension compatibility: Confirm bore size, extended and collapsed lengths, stroke, and mounting configurations with your specific truck and trailer models. OEM cross-compatibility (Gabriel, Monroe, etc.) is common, but verify fitment before purchase.
- Load and duty cycle: Heavy-haul and long-haul fleets may benefit from higher rebound and compression ratings, plus dust protection, to maintain stability under varying payloads and road conditions.
- Replacement strategy: Decide between single-vehicle replacements or multi-pack sets to standardize maintenance across a fleet. Multi-pack options can reduce downtime and simplify stocking plans.
- Installation considerations: Plan for safe vehicle lifting and securing, proper torque, and alignment with mounts. Incorrect torquing can compromise performance and safety over time.
- Material and build quality: Look for proven damper construction and corrosion resistance suited for highway use and exposure to road contaminants.
- Brand and compatibility network: Replacing with OEM-like specifications can help maintain ride characteristics. Cross-brand compatibility is common, but verify specific model numbers and series.
- Warranty and support: Check manufacturer warranties and clarity around returns, especially when buying in bundles for a fleet.
