Schumacher Cougar LD3 Fin Turnbuckle Kit Burnt Blue (JCO2969-1)

Schumacher Cougar LD3 Fin Turnbuckle Kit in burnt blue is a lightweight titanium turnbuckle set designed for the LD3 chassis. It features a roughly 3.7 mm titanium hex that tapers to a 3.5 mm threaded base, designed to accept Schumacher ball-cups after a small modification. The design highlights an extended adjustment hex area and the distinctive finned cuts that rotate around the center, combining performance-focused function with a premium look. The kit includes both left- and right-hand threads, with the left-hand side clearly marked for easy orientation, and the burnt blue finish shows intentional color variation for a striking appearance.

Designed for high-performance racing, these turnbuckles are the original JConcepts design—lightweight, precisely machined, and built to withstand the rigors of track use. The left- and right-hand threads allow straightforward setup of steering and suspension, while the revolve-cut styling contributes to a strong, race-ready profile. To use them with Schumacher ball cups, a small modification is required by drilling out the plastic parts with a 3.2 mm drill bit (not included). A dedicated turnbuckle wrench is sold separately to help with adjustments on the bench or at the track.
