As in custom gear? I use this meathod:

• Attach a hinge to the base of the gear
• input "clamp01(LandingGear)" into the hinge's input
• attach a shock to the hinge and set the spring strength and damper to 7.5 (which would be 750%)
• Put a small fuselage piece at the bottom of the shock to place a wheel on
• Remove suspension and steering for that wheel and adjust size accordingly.

If you want to add steering to the gear, put a rotator between the hinge and the shock and assign the input and steering angle into the rotator.

I hope this helps!
