Factor 55 UltraHook | Full-Size Truck Winch Hook + Closed System Winching® | Red

Is This for You?

• You're running a full-size truck winch and want the speed of a hook with the security of Closed System Winching® in a single product — the UltraHook is the industry's first full-size winch hook with a closed system shackle mount hole machined directly into the hook body. Use it as a conventional hook or a shackle mount — no rope splicing required for either configuration.
• You need two distinct load paths with separate ultimate strength ratings — 16,000 lb max load, with 31,000 lb ultimate strength at the hook throat opening and 48,000 lb ultimate strength at the shackle pin mount. The shackle pin mount is the stronger connection point by 55%.
• You want a hook that stows cleanly against your fairlead without rattling or scratching — EPDM rubber pads protect the fairlead from metal-to-metal contact and eliminate rattle. Integrated finger grips promote correct hook-up orientation. Max opening deformation is laser-engraved on the body for field reference.

The Result

• 16,000 lb maximum load / dual ultimate strength ratings — 31,000 lb at the hook throat opening, 48,000 lb at the shackle pin mount. 5/8" diameter 6Al-4V Grade V aerospace titanium double shear pin. Accepts rope and cable up to 3/8" diameter.
• 7000-series military grade aluminum body — CNC machined, 3" thick when folded flat, with closed system shackle mount hole accepting 3/4" screw pins and soft shackles up to 1/2".
• True Closed Loop System™ — latch pin stored in hook body locks the safety latch securely in the closed position for closed system winching without carrying a separate component.

The UltraHook is the full-size truck version of the UltraHook XTV, built to a higher load rating and larger hardware specification. The body is CNC machined from 7000-series military grade aluminum — a higher-strength alloy than the 6000-series used in the XTV, appropriate for the higher load ratings of full-size truck winches. The 5/8" diameter 6Al-4V Grade V titanium double shear pin is larger than the 7/16" pin in the XTV, reflecting the higher line loads of full-size truck winch applications. The double shear configuration distributes the pin load across two shear planes, reducing stress on the pin at rated load. The two separate ultimate strength ratings reflect two distinct load paths through the hook body: the hook throat opening (31,000 lb) is the load path used in conventional hook operation, where the strap or rope loop bears against the hook throat; the shackle pin mount (48,000 lb) is the load path used when a screw pin shackle is installed through the machined hole, which is a more efficient load path through the aluminum body. The shackle pin mount is 55% stronger at ultimate than the hook throat. The latch pin that locks the safety latch into the Closed Loop System™ position is stored in the hook body — it is always present and does not require a separate component. Max opening deformation is laser-engraved on the body — if the hook throat has deformed to or beyond that dimension, the hook must be retired from service. EPDM rubber pads protect the fairlead face and eliminate rattle during trail driving. 32 oz. 3" thick when folded flat. Engineered, tested, and made in the USA.

Audit Table

UltraHook vs. UltraHook XTV

Compatibility

✔ Full-size truck winches — steel cable or synthetic rope up to 3/8" diameter
✔ 3/4" screw pin shackles
✔ Soft shackles up to 1/2"
✔ Roller and Hawse (alloy) fairleads — EPDM rubber pads
✔ Factor 55 Closed System Winching® configurations

✘ Not designed for: UTV/ATV winches — see UltraHook XTV (00275) for powersports applications
✘ Not compatible with: Rope or cable diameters exceeding 3/8"

Usage Notes

• Inspect hook throat against the laser-engraved max opening deformation dimension before each use. Retire the hook from service if the throat has deformed to or beyond that dimension.
• Inspect shear pin and EPDM rubber pads at regular intervals. Replace if deformation, wear, or displacement is found.
• To engage Closed Loop System™: close the safety latch and insert the latch pin (stored in hook body) to lock the latch in the closed position.
• Do not exceed the 16,000 lb maximum load rating.

Engineering Question: Are you running a full-size truck winch with steel cable or synthetic rope, and what is your rope or cable diameter? The UltraHook accepts lines up to 3/8" diameter. Also confirm whether you plan to use the hook throat or shackle pin mount as your primary connection — the shackle pin mount provides 48,000 lb ultimate strength vs. 31,000 lb at the hook throat.
