Product Details
Everything you need to know — features, specs, fitment, and answers to the most common questions.
Copper contact surfaces
Copper carries current far better than plated steel — full cranking amps reach the starter instead of dying at the clamp.
Bites through corrosion
Sharp teeth and strong spring pressure cut through post oxidation for a solid first-try connection.
Fits top and side posts
Jaw profile grips standard top posts, side terminals, and jump lugs without slipping.
Lifetime warranty — no receipt
Spring weakens or jaw fails under normal use, we replace them.
- Can I use these to re-clamp my existing jumper cables?
- Yes — that's a common upgrade. Strip the cable ends clean, make a tight mechanical connection to the clamp, and you'll typically see noticeably better current delivery than worn factory clamps.
- Warranty terms?
- Lifetime warranty. If it fails under normal use we replace it — no receipt, no questions.
- How fast do orders ship?
- Orders before 2pm ET ship same day from Columbus, OH. Free standard shipping on orders $49+.

Clean bite on corroded posts
Our yard trucks sit for weeks and batteries die. These copper clamps bite through light corrosion and deliver full contact — jumps that used to take three tries connect first time now. Springs are strong enough to stay put on side posts.

Replaced the clamps on my jump pack leads
Factory clamps on my jump box were junk — poor contact, half-dead jumps. Swapped these on and the difference in current delivery is obvious; cranks that hesitated now spin over immediately. Copper contact surfaces earn their keep.

Good grip, watch your polarity marking
Used them reviving the mower and my daughter's sedan. Strong spring, teeth grip both top and side posts. The color marking could be bolder for quick reads in a dark garage — otherwise no complaints.
