 You are bidding on a brand NEW ARP MAIN Stud Kit part # 208-5404. Kit comes with all (10) main studs , (10) washers, and (10) nuts needed for a direct bolt on, as well as the ARP moly-lube and instruction sheet.


This kit is for bolting down the crankshaft main caps and fits all 1990-2001 Acura 1.8L B18A and B18B Series NON-VTEC engines , also works great for B20B and B20Z NON-VTEC engines.

IMPORTANT NOTE ! This kit is NOT for bolting on the cylinder head, please use ARP HEAD STUDS for that purpose, see second IMAGE ABOVE for clarification. 

ARP® uses a premium grade 8740 chromoly that is rated far superior to to "aircraft quality". Then, each stud is placed vertically in special racks and precisely heat-treated to 200,000 psi. This procedure ensures complete heat penetration and the results are far superior to those lesser quality studs from other manufacturers who just dump pieces in a basket and hope for the best.

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 ARP® 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. ARP® studs are thread rolled after heat-treat, which gives them about 1000% (thats ten times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice). 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.
