The TKR1119 Turnbuckle Wrench is a hardened steel dual-ended tool designed for adjusting RC turnbuckles and locknuts used on Tekno RC platforms such as the EB48, NB48, ET48, MT410, and SCT410 series. One end is sized at 5.5mm and the other at 7mm, allowing it to fit common M3 and M4 rod ends and link hardware found on 1/8-scale race vehicles. It is CNC-machined from hardened steel with a black coating for corrosion resistance, and its slim profile makes it ideal for tight suspension and steering areas where standard wrenches won’t fit. This tool is commonly used for precise suspension tuning, camber and toe adjustments, and general maintenance across Tekno RC buggies and trucks.
