Factor 55 Extreme Duty Soft Shackle | 1-1/8" x 24" | HMPE | Mining/Ag/Military

Is This for You?

• You're operating in mining, agriculture, or military recovery with a vehicle GVW between 35,000–55,000 lbs — and you need a soft shackle with a published 294,000 lb MBS and a 58,000 lb WLL, not a recreational-grade product adapted to a heavy-duty application.
• You're replacing steel screw pin shackles with a lightweight HMPE alternative that eliminates the projectile hazard of a steel shackle failure under load — HMPE soft shackles fall to the ground on failure rather than becoming a high-velocity projectile.
• You're running Closed System Winching® — this shackle is compatible with Factor 55's Closed System Winching technique, which uses closed-link rigging hardware throughout the recovery system to eliminate open hooks and unsecured connections under load.

The Result

• 294,000 lb MBS / 58,000 lb WLL — a 5:1 safety factor, rated for vehicles between 35,000–55,000 lbs GVW in mining, agricultural, and military recovery applications.
• 25–30% higher verified breaking strength than standard soft shackles on the market — not a marketing claim; lab- and field-tested to consistent, repeatable MBS values.
• HMPE Plasma rope core with woven polyester jacket, Fiber Lock coating, and whipped ends — abrasion and UV protection extended as close to the knot as possible, where unprotected soft shackles fail first.

High-Modulus Polyethylene (HMPE) Plasma rope is the core material in this shackle — it has a higher strength-to-weight ratio than steel wire rope of equivalent diameter, does not corrode, and does not store kinetic energy the way steel cable does under tension. When a steel cable or steel shackle fails under load, the stored elastic energy releases as a high-velocity projectile. HMPE soft shackles fall to the ground on failure — a critical safety distinction in mining, agricultural, and military environments where personnel are in proximity to the rigging. The woven polyester jacket is the primary abrasion protection layer — HMPE fiber is strong in tension but susceptible to abrasion damage from contact with rough surfaces, sharp edges, and repeated friction. The jacket is whipped and coated with Fiber Lock, a resin that bonds the jacket fibers and prevents fraying at the ends. Critically, the jacket is attached as close to the knot as possible — the knot area is the highest-stress point in a soft shackle under load, and it is also the point most exposed to abrasion from contact with shackle pins, fairlead edges, and recovery hardware. Standard soft shackles leave the knot area unprotected; this design extends jacket coverage to that zone. The 25–30% breaking strength advantage over standard market soft shackles is a function of both the HMPE Plasma rope specification and the knot geometry — Factor 55 lab- and field-tests to consistent, repeatable MBS values rather than publishing a theoretical maximum.

Audit Table

Compatibility

✔ Vehicles with GVW 35,000–55,000 lbs — mining, agricultural, and military platforms
✔ Factor 55 Closed System Winching® rigging configurations
✔ Direct replacement for steel screw pin shackles in heavy recovery rigging

✘ Not designed for: Light-duty recreational off-road recovery — this is a heavy industrial/military specification product; see Factor 55's recreational soft shackle lineup for Jeep and truck applications
✘ Not designed for: Vehicles under 35,000 lbs GVW — WLL and MBS are sized for the 35,000–55,000 lb GVW range

Usage Notes

• Inspect shackle before each use. Do not use a soft shackle with visible cuts, abrasion damage through the jacket to the core, or knot deformation.
• Do not exceed the published WLL of 58,000 lbs under any load condition.
• Keep shackle away from sharp edges under load — the jacket provides abrasion resistance but direct contact with sharp metal edges under tension will damage the core.
• Store out of direct UV exposure when not in use. Jacket provides UV protection during use; prolonged unprotected storage will degrade both jacket and core over time.
• Compatible with Closed System Winching® — verify all other rigging components in the system are also closed-link hardware before executing a closed system recovery.

Engineering Question: What is your vehicle's GVW, and are you replacing steel screw pin shackles in a mining, agricultural, or military recovery configuration? This shackle is rated for 35,000–55,000 lb GVW applications — confirm your vehicle weight class and rigging configuration, including Closed System Winching® compatibility requirements, before ordering.
