Schumacher Cat L1R Fin Turnbuckle Kit - Stealth Black (JCO2970-2)

Schumacher Cat L1R Fin Turnbuckle Kit in Stealth Black is a titanium adjustment set designed for the Cat L1R chassis. It centers on a 3.7mm titanium hex base that tapers to a 3.5mm threaded base, designed to work with Schumacher ball-cups after a small modification. The distinctive finned design adds a lightweight profile and smooth center rotation, combining precise geometry with a premium look that racers appreciate.

The kit includes left- and right-hand threads, with the left-hand thread clearly marked for easy orientation and quick setup. Titanium construction keeps weight down while delivering stiffness for repeatable toe-in and steering adjustments. A slight modification may be required to fit Schumacher ball-cups, including drilling out the plastic parts with a 3.2mm drill bit (not included).
