Question 1

What is the difference between a coupler lock and a coupler with an integrated lock?

Accepted Answer

A standard coupler lock is a separate device you add to an existing coupler — it blocks the coupler from connecting to a ball. A coupler with an integrated lock is the coupler itself, with the locking mechanism built into the body. This means the trailer cannot be towed without engaging the lock, which eliminates the failure point of a forgotten or improperly applied separate lock.

Question 2

What lock core comes standard, and can I upgrade it?

Accepted Answer

The standard lock core is the Cobra tubular key system — a non-copyable, high-security design that prevents hardware store key duplication. You can upgrade to the Proven Disc-Detainer (virtually pick-proof), or request a Medeco M3 or Abloy core for the highest security tier, available for an additional fee.

Question 3

What tow rating does this coupler support?

Accepted Answer

The Hyper Hitches Coupler with Integrated Lock is rated for 21,000 lbs towing capacity with a 2,000 lb maximum tongue load — suitable for heavy utility, boat, and livestock trailers.

Question 4

Is the lock core rekeyable if I lose a key?

Accepted Answer

Yes — the lock core is designed to be rekeyable and upgradable, which means if you lose a key or want to switch to a higher-security core, you can do so without replacing the entire coupler.

Question 5

What ball size is this coupler designed for?

Accepted Answer

The coupler is designed for a 2-5/16" ball, which is the standard size for most medium and heavy-duty trailers.

Question 6

How does the Medeco or Abloy option differ from the standard Cobra core?

Accepted Answer

Medeco M3 and Abloy are government and high-security facility grade lock systems. Medeco uses rotating pins that must align at both the correct height and rotation — making it extremely resistant to picking and bumping. Abloy uses a rotating disc mechanism that is virtually unpickable and designed for harsh outdoor and road conditions. Both are available by request for customers who need the highest level of key control.
