Grizzly Winch 12000 lbs 72.5:1 with Synthetic Rope and Air Free Spool
Climbing out of the cab knee-deep in mud just to flip a clutch lever is routine for anyone who winches a lot. Air Free Spool removes that step: you disengage the drum pneumatically, without walking to the front of the vehicle.
Otherwise this is the same fast design as the version without the air function: a 7.2 HP (5.4 kW) 12 V motor, a two-stage planetary gearbox and a 72.5:1 reduction giving 34 m/min unloaded. The rating is 12000 lbs on a single line, with 24 m of red 9.5 mm synthetic rope supplied.
Rating 12000 lbs, single line | Air Free Spool yes | Reduction 72.5:1 |

- 72.5:1 reduction with a two-stage planetary gearbox gives up to 34 m/min of line speed, several times what the 150:1 models manage.
- 7.2 HP (5.4 kW) 12 V motor keeps 13 m/min even at full load.
- 9.5 mm x 24 m synthetic rope with a black aluminium hawse fairlead.

Line performance
| Load (lbs) | None | 6000 | 8000 | 10000 | 12000 |
| Load (kg) | 0 | 2721 | 3630 | 4532 | 5443 |
| Line speed (ft/min) | 111.5 | 78.7 | 65.6 | 52.4 | 42.6 |
| Line speed (m/min) | 34 | 24 | 20 | 16 | 13 |
| Current draw (A) | 142 | 235 | 285 | 330 | 345 |
Even at the full 5443 kg the rope still travels at 13 m/min. Watch the bottom row: 345 A is the load your electrical system has to be designed around if you want that performance in practice.
The pneumatic function pays off in repetitive work: competition, back-to-back recoveries in a group, utility vehicles operated by one person. Every pay-out without walking to the bumper saves a minute and keeps your boots dry — over twenty recoveries in a day that adds up.
Remember that the air function needs a compressed air source on the vehicle. Without an onboard compressor, the simpler NOM-99077 with the same drivetrain will be the more practical buy.
Installation / notes
The body measures 623 x 174 x 222 mm with the standard 254 x 114.3 mm bolt pattern. Plan the routing for the air line to the clutch as well.
The electrical installation has to handle up to 345 A — proper cable cross-sections, clean earths and a battery in good condition. Our workshop can do the complete fit, electrical and pneumatic side included.
Why it is worth it
- Pneumatic drum release genuinely cuts the time it takes to set up a pull.
- Performance of the fastest model in the series: 34 m/min unloaded, 13 m/min at full load.
- The manual clutch stays as a fallback, plus a 24-month warranty.
If your vehicle already runs an onboard compressor and you winch often, this is the most convenient version in the range.
