RPM Stainless Steel Threaded Outer Hinge Pin Set 4x56mm Suits Traxxas X-Maxx 70510

The RPM 70510 Threaded Hinge Pin Set is a heavy-duty suspension upgrade for the Traxxas X-Maxx, designed to replace the stock outer lower A-arm hinge pins with a more secure threaded pin and locknut arrangement. Manufactured from stainless steel, the pins are built for demanding bashing and help eliminate reliance on the small retaining screws used with the factory hinge pins.

Each 4mm x 56mm pin is retained by an M3 locknut, creating a captured mounting system that reduces the chance of a hinge pin working loose or being lost during hard driving. RPM confirms compatibility with stock Traxxas X-Maxx A-arms as well as RPM X-Maxx A-arms, with minor arm modification required during installation.

FAQ

Where do RPM 70510 hinge pins fit on the X-Maxx? These pins are designed specifically for the outer lower A-arm hinge pin positions. They are not intended for every hinge pin location on the vehicle.

What is the advantage of the threaded design? The threaded pin and locknut arrangement removes the need for the small factory retaining screw, helping provide a more secure captured installation that is less likely to work loose during hard bashing.

Do these fit stock Traxxas X-Maxx A-arms? Yes. RPM confirms compatibility with stock X-Maxx A-arms, but some minor modification of the arms is required for correct installation.

Do these fit RPM X-Maxx A-arms? Yes. RPM specifically lists compatibility with its X-Maxx A-arms, including parts 82352, 82354 and 82355.

Can these replace CEN GS025 hinge pins? Yes. RPM states that part 70510 can replace CEN GS025 hinge pins, but the RPM design uses an M3 locknut rather than the 4mm locknut used by the CEN version.

Are these upper and lower hinge pins? No. RPM specifies that these are for the outer lower A-arm hinge pin position only.

Important Notes

• Designed for outer lower A-arm hinge pin positions only
• Minor modification of stock or RPM X-Maxx A-arms is required for installation
• Follow RPM installation instructions before modifying the suspension arms
• Do not assume these pins fit upper or inner hinge pin locations
• Check suspension movement after installation to ensure there is no binding
• Tighten the M3 locknuts securely without overtightening and restricting suspension movement
• Inspect hinge pins, locknuts and suspension arms regularly after hard bashing
