PRE-ORDER ONLY. These are our new, taller 2.9 anti-foams that come with 4 2.9 tuning rounds. Combined, these make a perfect fit with the new Proline Baja Pro-x tires. There is plenty of strength to support a heavy SCX 6 yet soft enough to slow crawl over the most extreme rocks.
One package includes 2 2.9 anti-foams and 2 2.9 tuning rounds for aBaja Pro-x tires. You will need 2 packages for 4 tires.
