Kranken is not a rubber band. It is precision-engineered from aerospace-grade 17-4 PH stainless steel, offering extreme corrosion resistance and unmatched cold-weather durability.

• Tension Output: Kranken delivers 29 lbs of tension—nearly 2x the tension of an average spider bungee (15 lbs). This constant, higher tension is what keeps your chains securely centered and prevents chain slap.
• Main Cable Break-Strength: Tested to over 550 lbs (the machine stopped before the cable broke).
• Cable Limiter: Features a 209 lbs safe-break design to protect your tires in extreme situations.

• Zero Corrosion: Our Salt Spray Test—24 hours of continuous exposure—resulted in zero corrosion and zero pitting. Your investment will not rust out after one winter.
• Impact Resilience: It survived a drop test from 4 stories (approx. 40 feet) onto the crank handle with only a superficial graze, proving its toughness.

Don't let damaged chains or failed bungees cost you time and money. Professional drivers know the true cost of chain failure.Feedback from the Road (300+ Professional Drivers):

• Cost of Failure: Chain loss and damage can cost drivers $600–$800 annually.
• Bungee Lifespan: Most professionals are forced to replace rubber bungees 3 times per winter.
• Storage Issues: Rubber bungees suffer from dry-rot and tension loss even while in storage.

• No Expiration Date: Unlike rubber tensioners that often expire in your trunk before their first use, Kranken has no expiration date.
• Massive Lifespan: Enjoy a 5–10x longer lifespan compared to spider bungees.
• Reduced Failures: Proven to deliver 80–90% fewer chain failures.
