203-4205 HEAD STUD KIT for Toyota Supra 3.0L 2JZ-GE 2JZ-GTE

You are bidding on a brand new 12010 HEAD STUD KIT. This kit fits the 1993-1999 Toyota Supra MKIV 3.0L 2JZGE & 2JZ-GTE Turbo engine. 12010uses a premium grade 8740 alloy that is rated far superior to aircraft quality. Then, each stud is placed vertically in special racks and precisely heat-treated to 190,000-220.000 Following heat-treat, each stud is centerless ground to make it as close to perfectly concentric as possible. This procedure involves about ten very slight cuts and results in an exceptionally straight part. It s important to note that lesser quality studs are not even centerless ground the material is thread rolled in bar stock form (mostly before heat-treat, when the material is easier to machine). Because 12010 studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned something that won t happen with inferior quality head studs.
