Schumacher Cat L1R Fin Turnbuckle Kit Burnt Blue (JCO2970-1)

Schumacher Cat L1R Fin Turnbuckle Kit in Burnt Blue is a precision titanium turnbuckle set designed for the Schumacher Cat L1R RC car. Its finned profile and extended adjustment hex area provide lightweight strength along with precise, repeatable steering and suspension tuning.

Built around a 0.143-inch (3.7mm) titanium hex that tapers to a 3.5mm thread base, these turnbuckles are designed to accept Schumacher ball cups after modification. They feature left- and right-hand threads with the left-hand side clearly marked for easy orientation, and the burnt blue finish shows sporadic color variation. As an original JConcepts design, they are a popular choice in racing for performance tuning. To install with Schumacher ball cups, plastic parts may require drilling with a 3.2mm drill bit (not included). A separate JConcepts turnbuckle wrench is available to simplify adjustment.
