Stainless Tow Bar Anti-Rattle Shim | 4-Piece Kit

The Couplemate™ Anti-Rattle Shim kit is specifically engineered to eliminate the excessive slack between the tow bar and the hitch/receiver.

When installed, these anti-rattle hitch shims secure the receiver shank, stopping your hitch from rattling within the tow bar.
You can watch the official fitting guide below or read a step-by-step tutorial here.

Why Does Receiver Bar Rattle Occur?

Rattle occurs due to space between your tow bar and hitch/receiver. Tow bar shims are the best way to reduce rattle.

Most Australian tow bars are a 50mm x 50mm box section, which is why our premium cast receivers have a 2-inch shank. However, not all tow bars on the market are this size, meaning that the additional space generates a rattling noise.

Couplemate™ Engineers generally recommend steering away from Hitch Clamps, as the installation is difficult to do correctly and safely. Instead, customers chasing an anti-rattle tow hitch may have a better experience using our Stainless Shim Kit.
