This tool answers "what size kinetic recovery rope do I need" for your exact vehicle. Enter your vehicle (or its GVWR and/or curb weight) and a budget tier, and it returns a diameter class from WARN's published brochure, a minimum breaking strength (MBS) target computed from two different published manufacturer methods, and a tier-matched rope pick, each sourced and linked to the full guide behind it. The static diameter chart further down this page covers the same four sizes at a glance if you'd rather match your vehicle's weight yourself.
Read before you rig
Recovery gear stores serious kinetic energy. A failed rope, strap, or shackle can whip back with enough force to injure or kill. Keep everyone clear of the load path, never exceed a component's rated capacity, and follow your gear manufacturer's manual. Where it differs from anything on this page, the manual wins. This article is spec-and-evidence analysis, not field instruction from a certified instructor. If you're not confident rigging the pull safely, that's a reason to call someone who is, not a reason to guess.

Kinetic Rope Diameter Chart by Vehicle Weight
Every diameter this site carries a verified pick for, in one table: minimum breaking strength, the manufacturer-stated vehicle-weight range it's built for, typical lengths, and which pick above covers it. The MBS and vehicle-weight figures below match, row for row, the size chart on our full kinetic rope guide. Lengths and the pick column pull from each product's own page, so they can carry extra detail (alternate length options, additional verified brands at a diameter) the guide's summary table doesn't show; see the full guide for every alternate brand at each diameter, not just the single pick shown here.
| Diameter | MBS | Vehicle-Weight Class | Typical Lengths | The Pick |
|---|---|---|---|---|
| 5/8 in | 14,800 lbs (source) | 1,400-2,999 lbs (SXS/UTV) | 20 ft, 30 ft | Yankum Ropes 5/8" Kinetic Recovery Rope "Viper"Best for UTVs and Light Vehicles |
| 7/8 in | 28,500-28,600 lbs | 5,000-7,200 lbs | 30 ft (also sold in 20 ft) | Bubba Rope Power Stretch Recovery Rope 7/8" x 30'Best OverallPlus 3 verified alternates at this diameter: Rhino USA, GearAmerica, and Yankum Python. See the guide. |
| 1 in | 33,500 lbs (source) | 7,200-10,249 lbs | 20 ft, 30 ft (color options available on 30 ft only) | Yankum Ropes 1" Kinetic Recovery Rope "Rattler" (30')Best 1-inch for Full-Size Trucks |
| 1.5 in | 78,200 lbs (source) | 14,500-22,999 lbs | 20 ft, 30 ft | Yankum Ropes 1 1/2" Kinetic Recovery Rope "Cobra"Best 1.5-inch for HD Trucks and RVs |
UTVs use 5/8", not 7/8" or 1": Yankum's Viper is manufacturer-scoped specifically to 1,400-2,999 lb SXS/UTV recovery vehicles, not a scaled-down truck rope. This site publishes no GVWR threshold separating the 7/8", 1", and 1.5" truck classes (WARN's brochure sorts them by vehicle description, not a numeric cutoff), so use the calculator on this page's vehicle-class picker to match your own rig rather than guessing from weight alone.

How the Sizing Logic Works
Nothing below is a new formula invented for this tool. Every computed number reuses a published rule already cited on this site's kinetic rope guide, cross-linked here so you can verify it against the original source.
Diameter class
Diameter class comes from the WARN kinetic-rope sizing brochure (linked via Factor 55): 7/8" for Jeeps, mid-size trucks, and SUVs; 1" for full-size trucks and SUVs; 1.5" for HD trucks, vans, and RVs. This site has no published GVWR threshold separating those three classes, so the calculator on this page asks which class matches your vehicle rather than guessing a cutoff, and leaves that selection genuinely optional: skip it and you still get your MBS target range, just not a specific diameter or product pick.
MBS target: this calculator's two methods, two weight bases, never blended
Minimum breaking strength (MBS) is shown as a spread between two different published manufacturer methods on two different weight bases: Bubba Rope's 3-4x curb weight, and ARB/MAXTRAX's 2-3x GVW. Applying Bubba Rope's method to a 4,500 lb curb weight gives a minimum MBS of 13,500-18,000 lbs. Applying ARB/MAXTRAX's method to a 6,000 lb GVWR gives a minimum MBS of 12,000-18,000 lbs, a different number built on a different, heavier weight figure. Neither number is more "correct" than the other; they're two separate published rules, and this tool never averages them into one figure. Enter both your curb weight and GVWR to see both ranges side by side; enter just one and you'll see that single method's range, clearly labeled by basis.
Door-jamb disclosure
Every GVWR-based number here, whether you picked a vehicle from the list or typed a GVWR in by hand, is computed from a manufacturer's published range for that model line, not a certified measurement of your specific vehicle. Trim, options, and running changes shift the real number within that range. Your exact GVWR is stamped on the driver's-side door jamb or B-pillar placard, per NHTSA regulation: check it before you buy rated gear, the same disclosure this site's other calculators and vehicle tables carry.
Frequently asked questions
What size kinetic recovery rope do I need?
It depends on your vehicle's weight class and, for the exact MBS target, its curb weight and/or GVWR: there's no single rope size that fits every rig. Use the calculator on this page to get a diameter class from WARN's published brochure, an MBS target range from two different published manufacturer methods, and a tier-matched pick, each linked to the sourced guide behind it.
Is there a kinetic rope size calculator?
Yes, this one. Pick your vehicle from the 23-vehicle dropdown above, or enter its curb weight and/or GVWR by hand (either is enough on its own; entering both gets you both published MBS methods at once), and get a diameter, an MBS target range, and a budget/mid/premium rope pick in one pass. Every figure links back to the manufacturer spec it came from.
What size rope do I need for a 6,000 lb truck?
Applying ARB/MAXTRAX's published 2-3x GVW method to a 6,000 lb GVWR gives a minimum MBS target of 12,000-18,000 lbs. A 7/8" rope at 28,500-28,600 lb MBS clears that with substantial margin and is the brochure-published diameter for most Jeeps, mid-size trucks, and SUVs in that weight range; a full-size truck at the same 6,000 lb GVWR could still be sized to 7/8" or step up to 1", depending on which WARN vehicle-description class it falls into. Enter 6,000 in the GVWR field on this page (and your curb weight, if you know it) to get the exact computed range and a matched pick.
How do I know what size rope I need if I don't know my GVWR?
Check the driver's-side door jamb or B-pillar placard: federal regulation requires every vehicle to carry its exact GVWR there. Don't have curb weight or GVWR handy at all? Pick your vehicle from the vehicle dropdown on this page instead; this tool already has each of the 23 vehicles' manufacturer-published GVWR range on file.
Does a UTV need a different kinetic rope than a truck?
Yes. UTVs and ATVs typically have no published diameter class from WARN's truck-focused sizing brochure, so this tool recommends the site's UTV-scoped 5/8" pick (Yankum's Viper, manufacturer-designated for 1,400-2,999 lb SXS/UTV recovery vehicles) instead of a scaled-down 7/8" truck rope. Select "ATV / UTV" in the vehicle type radio on this page, or pick a UTV directly from the vehicle dropdown, to get that path.
Does this tool show prices?
No. Prices and availability change constantly, and a static number here would go stale the moment a manufacturer or Amazon changes it. Every pick is labeled budget, mid-range, or premium instead, and its Amazon link shows you live, current pricing.
