Synthetic vs steel
Synthetic winch rope instead of steel
HMPE and Dyneema® SK75/SK78 weigh a fraction of steel cable, float, and give much less recoil than steel on break — not zero, but safer because it is rope, not flying steel pieces. Choose diameter and length for drum and WLL — not for marketing numbers.
Buying guide
Diameter, length & finish
Four steps to choose the right winch rope — without exceeding the WLL of your winch.
Match drum & WLL
Choose diameter for the drum groove and the WLL of your winch — not for marketing MBL. Product pages show the manufacturer rating; measured HMPE reference is below.
Drum capacity first
Longer rope = more layers on the drum. Check your winch capacity; extend with winch ropes (extensions).
Hook or eye
Ready-to-use winch ropes with hook for recovery; stainless eyes on extensions. Softshackle as the connection instead of a bow shackle.
WLL ≠ MBL ≠ measured
WLL = working load · MBL = minimum breaking load (manufacturer) · measured (Otto) = what we pulled ourselves. Never mix them up.
Types
SK75, T70 or Prorope HMPE
Three UHMWPE routes. Dyneema® only for genuine SK75/SK78; otherwise HMPE.
SK75
Dyneema® SK75 — yellow, high abrasion resistance
Genuine Avient fibres. The pick for intensive winch work and 4×4. We only say Dyneema® for real SK75/SK78.
T70 Hawkline
Soft, flexible, keenly priced
UHMWPE class comparable to SK75, softer construction. Easier to splice. Ideal for standard winch work.
Prorope HMPE
UHMWPE performance, sharper priced
Technically nearly identical to SK75. No Dyneema brand name — but measured in our lab (e.g. 4 mm 1,827 kg).
Our test bench
Measured HMPE reference
Only measured (Otto) — Otto Tromm, Beringe · protocol based on ISO 2307:2019 · min. 5 pulls · 50 kN. Reference HMPE for winch class; product SKUs 6–16 mm: check the manufacturer rating on the product page.
| Rope | Diameter | Construction | Breaking strength | ≈ kg |
|---|---|---|---|---|
| Prorope HMPE | 4 mm | 12-strand braided | 17,926 N | 1,827 kg |
| HMPE white + PES cover | 5 mm | Core with cover | 10,166 N | 1,036 kg |
| HMPE blue/gold | 5 mm | Braided | 9,266 N | 945 kg |
| HMPE + PES cover | 4 mm | Core with cover | 6,698 N | 683 kg |
| Dyneema SK78 + PES | 6 mm | Core with cover | 12,380 N | 1,262 kg |
Comparison
Synthetic vs steel cable
| Property | Synthetic (HMPE/Dyneema) | Steel cable |
|---|---|---|
| Weight | Up to 85% lighter | Heavy |
| Recoil on break | Much less (not zero); rope instead of steel pieces | Dangerous (flying steel) |
| Buoyancy | Floats | Sinks |
| Corrosion / splinters | None | Rust, broken wires |
| Handling | Flexible, hand-friendly | Stiff, gloves needed |
| Elongation at break | < 4% | 1–2% |
More context: Dyneema vs steel.
Companion
Add a softshackle
A softshackle replaces the bow shackle: light, quiet, no edges that damage the rope. Pair it with your winch rope for recovery on 4×4 or boat.
Safety
Short & clear
Respect the WLL
Work within the working load of winch and rope. MBL / measured kg are not a usage limit.
Inspect before every pull
Wear, coating, splices, hook. Replace if in doubt — no guarantee against injury.
FAQ
Frequently asked questions about winch ropes
SK75, T70 or HMPE for the winch?
SK75: highest abrasion resistance (yellow, genuine Dyneema®). T70: more flexible. HMPE: same UHMWPE class, sharper priced. Dyneema® only for genuine SK75/SK78.
Why synthetic instead of steel cable?
Lighter, floats, no rust, much less recoil than steel on break — not yet minimal, but less dangerous because it is rope, not flying steel pieces. Steel stays heavy and has snap-back risk.
What is the difference between WLL, MBL and measured kg?
WLL = working load (usage limit). MBL = minimum breaking strength per manufacturer. Measured (Otto) = what we pulled on our own bench. Never use MBL/measured as WLL.
Are all kg on this page measured?
Yes — only the HMPE/SK78 reference rows in the table. Diameter tables on product pages can be manufacturer ratings; check the label.
Can I extend?
Yes — see winch extensions with stainless eyes (in winch ropes). Softshackle as the connection instead of a bow shackle.
Ordered before 13:00?
On weekdays: ordered before 13:00 = shipped today from our own stock. Free shipping from €100.
Ready to choose a winch rope?
Pick SK75, T70 or HMPE — and check softshackles for recovery. Only measured kg in the table; WLL stays leading.
