Cables versus fabric. The Super Z6 grips harder, lasts longer, and is unambiguously a 'chain' under every chain law; the AutoSock goes on in two minutes with bare hands, fits cars with zero clearance, and is accepted as an alternative traction device in many states — but it shreds on bare pavement and isn't accepted everywhere. If your car can take the Super Z6, it's the better traction device. If it can't, or you know you'll never actually fit chains on a shoulder, the AutoSock is the one that gets used.
Pick the Security Chain Company if…
- ✓Your wheel wells have room for a Class S cable chain
- ✓You want maximum grip and durability per dollar
- ✓You drive where chain laws may not accept fabric devices
Pick the AutoSock if…
- ✓Sports or luxury car with zero clearance (manual prohibits chains)
- ✓You want the easiest possible install
- ✓Your state accepts AutoSock as a traction device (verify)
