Ok I have a problem I've used tit turnbuckles on all my cars ..I built a new 44.3 and put on track yesterday ,the 2nd lap jumped a crossover never crashed landed smooth and a rear turnbuckle snapped right at threads like a flaw or something ..had put a stock one back,in for rest of day.will jconcepts sell just one or warranty one,,I would understand if I crashed or something or landed funny...
