Buy a winch that’s too small and it stalls halfway out of the ditch. Buy one far bigger than you need and you add weight and strain your front end doesn’t need. The right size starts with one number on your door jamb sticker.
Find your vehicle’s gross vehicle weight rating (GVWR) on the driver’s door jamb sticker, add the weight of any bumpers, racks or gear, multiply by 1.5 and round up to the next winch size. For powersports, Warn’s guidance is 2,500 to 3,500 lb for an ATV, 3,500 to 4,500 lb for a two-seat UTV and 4,500 to 5,500 lb for a four-seat UTV.
How do you work out what size winch you need?
The standard rule is GVWR × 1.5 = minimum winch rating.
GVWR is the most your vehicle is rated to weigh fully loaded, not what it weighs empty. You’ll find it on the sticker in the driver’s door jamb or in the owner’s manual. The loaded number matters because a stuck vehicle is rarely empty: passengers, tools, a full tank and whatever’s in the box all count.
- Find the GVWR on your door jamb sticker.
- Add the weight of anything bolted on since: a steel bumper, roof rack, rooftop tent or drawer system.
- Multiply the total by 1.5.
- Round up to the next winch size sold.
| Example GVWR | Minimum winch (× 1.5) | Round up to |
|---|---|---|
| 5,000 lb (2,268 kg) | 7,500 lb (3,402 kg) | 8,000 to 9,500 lb |
| 6,000 lb (2,722 kg) | 9,000 lb (4,082 kg) | 9,500 lb |
| 7,000 lb (3,175 kg) | 10,500 lb (4,763 kg) | 12,000 lb |
| 10,000 lb (4,536 kg) | 15,000 lb (6,804 kg) | 18,500 lb |
The GVWR values above are worked examples. Use the number on your own sticker, since two trucks with the same name can differ by cab, box and engine.
What size winch does an ATV or UTV need?
Powersports winches are sized by machine type rather than the 1.5 formula. Warn publishes these ranges by machine:
| Machine | Winch range | Options at KS Products |
|---|---|---|
| ATV | 2,500 to 3,500 lb (1,134 to 1,588 kg) | Novawinch Super B 2500 lb, wire rope, Novawinch Fenix 3500 lb, synthetic rope |
| Two-seat UTV | 3,500 to 4,500 lb (1,588 to 2,041 kg) | Novawinch Super B 3500 lb, synthetic rope, Novawinch Fenix 4500 lb, synthetic rope |
| Four-seat UTV | 4,500 to 5,500 lb (2,041 to 2,495 kg) | Novawinch Super B 4500 lb, synthetic rope |
A 4,500 lb winch sits at the bottom of the four-seat range. If your four-seater carries a full crew and gear, check its loaded weight before settling on that size.
What size winch does a truck or SUV need?
Work backwards from the winch sizes available. Divide each rating by 1.5 and you get the heaviest GVWR it covers.
| Your GVWR (with add-ons) | Winch size | Options at KS Products |
|---|---|---|
| Up to 6,300 lb (2,858 kg) | 9,500 lb (4,309 kg) | Novawinch Pro Plus 9500 lb, synthetic rope |
| Up to 8,000 lb (3,629 kg) | 12,000 lb (5,443 kg) | Novawinch Stinger 12000 lb, wire rope, Novawinch Stinger Plus 12000 lb, synthetic rope |
| Up to 8,300 lb (3,765 kg) | 12,500 lb (5,670 kg) | Novawinch Pro Plus 12500 lb, synthetic rope |
| Up to 12,300 lb (5,579 kg) | 18,500 lb (8,392 kg) | Novawinch Pro 18500 lb, wire rope |
The 12,000 and 12,500 lb sizes sit close together. If your GVWR sits close to 8,000 lb, the extra 500 lb gives you a little room for gear you add later.
Why doesn’t a winch always pull its full rating?
A winch’s rating applies to the first layer of rope on the drum. Warn’s winching guide notes that pulling power drops as more layers build up, so a winch with most of its rope still wound on pulls less than the number on the box.
Three habits get you closer to the full rating:
- Spool out as much rope as you can and pick a distant anchor, so fewer layers stay on the drum.
- Use a snatch block to double the line. Warn notes this increases pulling power and reduces the layers on the drum.
- Pull as straight as you can. Side pulls pile rope up at one end of the drum.
Leave at least 5 wraps of steel rope or 10 wraps of synthetic rope on the drum at all times, per Warn’s guide. A vehicle buried to the frame in snow or mud also needs far more pull than the same vehicle on firm ground. The 1.5 margin gives you room for that, and a snatch block gives you more.
Can a winch be too big?
Yes. Going one size above your minimum is sensible. Going far past it adds weight over the front axle, and off-road testers warn that an oversized winch can damage your own vehicle or the one you’re recovering. Whatever you choose, the bumper or mounting plate must be rated for that winch.
Steel cable or synthetic rope?
Both work. The choice comes down to how you’ll use it.
- Synthetic rope is lighter and easier to handle with gloves on. It needs at least 10 wraps left on the drum.
- Steel wire rope handles dragging over rock and gravel better. It needs at least 5 wraps left on the drum.
Several sizes come both ways, such as the Stinger 12000 lb in wire rope or synthetic rope, so you can pick the size first and the rope second.
What does your vehicle need to run an electric winch?
An electric winch draws hard on your battery. Warn recommends a fully charged battery with at least 650 cold cranking amps for peak performance. In a Canadian winter, start with a healthy battery and keep the engine running while you winch. Watch your voltage, because an idling engine may not charge as fast as the winch drains.
Long pulls also heat the motor. Stop between pulls to let it cool. A wireless remote lets you stand well clear of the rope while you work. The Novawinch Duo wireless remote is built for Pro Plus series winches.
Electric or hydraulic winch?
Electric winches run off the battery and suit most trucks, SUVs and powersports machines. Hydraulic winches run off a vehicle’s hydraulic system, usually the power steering pump, and suit work trucks that winch often. KS Products carries Novawinch HEN hydraulic winches, such as the HEN12000 hydraulic winch.
Can you lift with a vehicle winch?
No. Warn’s safety guide says never use a winch as a hoist or to hold a hanging load. Vehicle winches are built to pull along the ground. For lifting, use a product sold as a hoist, such as the Novawinch CH500 hoist.
Quick answers
What size winch do I need for a Jeep Wrangler?
Warn’s own example uses a two-door Wrangler Rubicon with a GVWR of about 5,000 lb. Multiplied by 1.5, that’s a 7,500 lb minimum, so an 8,000 lb winch is the starting point. A 9,500 lb winch clears it with room to spare. Four-door models are heavier, so check your sticker.
Is a 9,500 lb winch enough for a half-ton truck?
Only if your GVWR, plus any add-ons, is about 6,300 lb or less. Half-ton GVWRs vary by cab, box and engine. Check the sticker. If you’re over 6,300 lb, step up to a 12,000 lb winch.
Can I use a recovery strap with a winch?
No. Warn’s guide says never use a recovery strap in a winching operation. A recovery strap is designed to stretch and store energy for snatch recoveries. Use a tree trunk protector for the anchor and a shackle to connect.
