Продам ARP 251-5402 Main stud kit for FORD Ecoboost 1.6L 4cyl в ОАЭ, ДубайОбъявление #27511

ARP studs are thread rolled after heat-treat, which gives them about 2000% (that’s twenty times) better fatigue strength than those studs that are threaded prior to heat-treat. It costs a lot more to do it this way, because it’s tough on tooling, but the results are well worth the extra effort.
