Traxxas is now offering another options for upgrading your 4×4 models with these Heavy Duty Steel Constant Velocity units. Designed for the increased torque and traction of the larger Hoss MT platform, these telescoping driveshafts won’t limit suspension travel while also providing smooth steering under power. The cross pins and grub screws are retained, preventing a failure in the field. Further strengthening the units are 10mm CV balls and high-grade steel stub axles.
