SKU: RPM70510 | Brand: RPM | Product: RPM Traxxas X-Maxx Threaded Hinge Pins 70510 RPM 70510 is a threaded hinge pin set designed for the Traxxas X-Maxx outer A-arm locations. Manufactured from stainless steel, each kit contains 4 hinge pins measuring 4mm x 56mm and 4 M3 locknuts. These pins are compatible with both stock and RPM A-arms, and serve as direct replacements for CEN GS025 hinge pins (note: RPM uses 3mm locknuts versus the 4mm specification on CEN versions). Minor A-arm modification may be required for proper installation. This component eliminates the need for traditional retaining screws.
