This is a pack of two replacement Traxxas 49mm Turnbuckles. These turnbuckles are 82mm from center to center and come assembled with rod ends and hollow balls. Package includes one left and one right side.
Traxxas 49mm Camber Link Turnbuckle (2) (82mm center to center)
These camber links w/ turnbuckle are engineered to fail OR are the cheapest possible solution to the mechanical need. They claim these are steel but they are extremely brittle and their cross-section looks more like powdered metal / casting than what they should be made of, a drawn steel wire that has a flat spot stamped into it and one threaded end.
Traxxas should be ashamed of themselves for selling parts like this. They set everyone up on a "subscription" model where people buy what they believe is a premium product only to have chronic mechanical failures and required parts replacement at big, big $$$$.
They of course have the anodized version of these but if you scale the price of those to every part on the model, a Traxxas Rustler 4x4 vxl would cost $3000.
