Nice solid quality (non-magnetic!) titanium turnbuckle with 3mm diameter and 42mm length.
Threaded lengths on each size are about 8mm.
Main purposes are as toe and camber adjustment rods.
A size that can commonly be used on (but is not restricted to) 1/10 buggies.
Recommended additional item for adjustment is the 3Racing (#3RAC-TR3/V2) 3mm aluminum turnbuckle tuner.
Needs ball ends with 3mm thread for final assembly.
Recommended product for many applications with a great price to quality ratio!
