When bolts just aren't strong enough, you have to go to main studs. Our ARP main cap stud kit are the strongest main studs you can buy for the big block Mopar engine.
Whenever you order bolts, don't forget a tube of ARP assembly lubricant. ARP's new "Ultra-Torque" is a special new blend of PFTE lube which ensures the correct torque will be reached on the first pull, so there is no longer any need to "cycle" the fastener (or loosen and tighten it several times), which has been the case with ARP's regular "Moly Lube" This lube is essential to get correct torque on the head, rod and main bolts, and it doesn't hurt to put it on misc other engine bolts as well. One tube is usually enough to do 4 or 5 complete engines, so it's a good investment to keep around the shop.
We now carry the special 5.200" long ARP studs which are supplied in our main girdle kit. These feature the extra long threads on the top end of the stud to allow for the extra thickness of the girdle plate, shims and hold down nuts. Normally, 8 of these are required for a complete engine, the rear (#5) main cap uses standard length studs since longer studs are impossible to use in this location due to the interference with the rear seal cap. We offer these individually for service replacement purposes with our own girdle kit, or for those who buy the girdle plate elsewhere and need the special studs.
Use our premium Permatex BLUE Loctite on all applications which need to be held in place, but are still intended to be broken loose from time to time. We always use this on certain parts of the engine which tend to come loose occaisionally due to harmonics, even when they are torqued correctly during assembly. Big Block Mopars are famous for this on torque coverter bolts, rocker arm hardware, cam sprocket bolts, etc. We highly recommend it for those applications. One small tube is usually enough to do one complete engine. Made in the USA!
Use our premium Permatex RED Loctite on all applications which need to be held in place near permanently, and you don't expect to need to break loose. One small tube is usually enough to do one complete engine. Made in the USA!
