RC4WD NARROW 5-LUG PIN-MOUNT HUBS FOR 1.55″ LANDIES WHEELS (4) Z-S1940

SET OF FOUR 3.6 MM NARROWER OFFSET CNC-MACHINED BILLET ALUMINUM

Pull compatible RC4WD 1.55-inch Landies wheels inward by 3.6 mm compared with the stock wheel hub while adding a detailed five-lug hub/brake-disc appearance. Z-S1940 is a purpose-built narrow pin-mount system for Z-W0076not a universal 1.55-inch wheel adapter.

WHAT THE 3.6 MM CHANGE MEANS

RC4WD states that this hub narrows wheel offset by 3.6 mm over the stock wheel hub. Moving the wheel inward can improve fender coverage and restore a period-correct narrow track, but it can also reduce clearance to steering knuckles, links, shocks and bodywork. Measure the current position before disassembly and test one corner before completing all four.

CONSTRUCTION AND DIMENSIONS

EXACT COMPATIBILITY

RC4WD lists Z-S1940 for the 1.55-inch Landies Vintage Stamped Steel Beadlock Wheels in white (Z-W0076). The five-lug appearance, center-hole size and included fasteners belong to that system. Similar-looking stamped wheels are not automatically compatible.

• Verified wheel: Z-W0076.
• Optional axle families shown by RC4WD include Yota and Yota II scale axles, but the complete vehicle setup must still be measured.
• Wheel, tire and axle are not included.

CRITICAL AXIAL WARNING

Z-S1940 does not work on Axial SCX10 or SCX10 II axles because of axle-thread fitment. RC4WD also notes that some Axial axle installations may require a washer or spacer because of thread depth. These statements are not interchangeable: a washer or spacer should not be treated as a remedy for the models RC4WD explicitly excludes.

If the axle is not clearly identified, stop and verify the axle model, exposed thread length, center clearance and pin interface before purchase.

WHAT IS INCLUDED

• 4 wheel hub/brake discs
• 20 M2 8 mm steel flat-head socket-cap screws
• 20 regular M2 black nuts

Not included: Z-W0076 wheels, tires, axle, vehicle, washer or spacer.

INSTALLATION PROCEDURE

1. Measure the current wheel-to-body and wheel-to-knuckle clearances.
2. Confirm the axle is not an excluded SCX10 or SCX10 II design.
3. Disassemble one wheel and retain the original components for comparison.
4. Install the Z-S1940 hub using the supplied M2 hardware, starting every fastener before final tightening.
5. Tighten in a crossing pattern so the hub seats flat against the wheel.
6. Mount the wheel and verify axle-thread engagement; do not accept partial or questionable nut engagement.
7. Rotate the wheel and check full steering lock and suspension travel.
8. After the first trail run, recheck every wheel fastener and axle nut.

HARDWARE PRACTICE

Use a correctly sized driver and moderate hand torque on the M2 hardware. If threadlocker is appropriate, apply only a tiny amount to clean metal-to-metal threads. Keep it away from plastic, painted surfaces and tire rubber. A miniature screw is secured by even clampingnot by seeing how brave your wrist feels.

TECHNICAL SUMMARY

GASHEAD RC FITMENT CHECK

Verify Z-W0076 wheel, axle model, pin interface, available thread engagement and inward clearance. If any of those five items are uncertain, measure first. This part changes the trucks stance and axle engagement; it should not be selected from wheel diameter alone.
