Heavy Duty Pivot Balls

These are the new heavy duty pivot balls for the Dart cars. The threads have been increased to 6-32. The redesigned cone shape from the collar to the ball increases the strength as well. These set the rear roll center to the maximum lowest position. No spacers are needed near the collar with this set. If you want to adjust the rear roll center height, then you don't want these, instead you'd want the heavy duty short collar version.

For the Dart 1.0, you will need to drill out your Float Bridge with a 9/64" drill bit to accommodate the larger 6-32 threads. (The Dart 2.0 car already has the larger holes in the float bridge.)

Sold in pairs.
