3Racing 3RAC-TR3/V2 Aluminium Turnbuckle Tuner  [3RAC-TR3/V2]

Accurate turnbuckle tuning tool

The 3Racing 3mm Aluminum Turnbuckle Tuner is a straightforward tool for achieving repeatable suspension settings. Constructed from solid aluminium, it offers a reliable feel and long service life. The 3.1mm header gap accommodates the majority of standard turnbuckles used in model cars and buggies.

Why this tuner suits model setup

Its slim aluminium profile makes it easy to reach tight areas while keeping weight negligible. The precise notch engages turnbuckle flats cleanly so you can fine tune steering and wheel alignment without slipping.

Practical advice for tuning sessions

Work on a level bench and adjust opposite sides in small increments to maintain balance. Check links and ball joints for wear before adjusting and store the tuner in a dry case to preserve its fit and finish.
