Anderson Lower Rod Shim Kit for 3/8 inch and 1/4 inch Lower Rods

The Anderson Lower Rod Shim Kit is a 12-piece hardware set designed to eliminate play and wobble in Anderson detector shaft lower rod connections. Detectorists running Anderson carbon fiber shafts on Minelab Equinox or other compatible detectors face connection looseness over time as rods wear against the cam-lock fittings, and this kit restores tight fit by providing precision shims in the two most common Anderson lower rod diameters. Each kit includes six shims for 3/8 inch diameter rods and six shims for 1/4 inch diameter rods, all machined to .020 inch thickness for incremental fit adjustment. When your Anderson lower rod develops side-to-side movement or the cam-lock no longer holds the coil angle securely, adding one or two shims between the rod and the locking collar brings the assembly back to factory-tight performance without replacing the entire lower rod.

What's Included with the Anderson Lower Rod Shim Kit

• Anderson Lower Rod Shim Kit (12 pieces total)
• Six 3/8 inch diameter shims at .020 inch thickness
• Six 1/4 inch diameter shims at .020 inch thickness

Why Anderson Shaft Owners Reach for the Shim Kit

• Restores tight cam-lock fit on worn lower rods without replacing the entire shaft assembly, saving the cost of a new lower rod when only the connection interface needs adjustment.
• Eliminates coil wobble and angle drift mid-hunt, keeping the search coil stable in the position you set rather than sagging forward or rotating as you swing.
• Covers both Anderson lower rod sizes in one kit, so detectorists running multiple Anderson shafts (24-inch and other lengths) or switching coils across different rod diameters keep spares on hand for any configuration.
• Machined to .020 inch thickness for precise incremental adjustment, you add shims one at a time until the cam-lock holds firm without over-tightening the collar.
• Affordable field repair that extends the working life of your existing Anderson carbon fiber lower rod rather than retiring a rod that's otherwise structurally sound. Compare to the Anderson 24 Inch Equinox Carbon Fiber Lower Rod when a full replacement is needed.

Precision Shim Fit for Anderson Cam-Lock Assemblies

Anderson detector shafts use a cam-lock system to secure the lower rod inside the upper shaft tube, and over time the repeated locking and unlocking wears the rod's outer surface where it contacts the cam mechanism. The shims in this kit are precision-cut to .020 inch thickness and sized to wrap around the lower rod at the cam-lock interface, increasing the rod's effective diameter just enough to restore the original snug fit. Most users find that one or two shims per connection eliminate play, and the kit's 12-piece count covers multiple repairs or lets you keep spares in your field kit. The shims work with any Anderson lower rod that uses the standard cam-lock design, including the carbon fiber rods sold for Minelab Equinox and other detector models. Installation takes under a minute: loosen the cam-lock, slide the shim onto the rod, reinsert the rod into the upper shaft, and tighten the cam until the rod holds firm with no side-to-side movement. Detectorists who swap coils frequently or hunt in sandy environments where grit accelerates wear keep a shim kit in the truck for quick field adjustments.
