The GOOD Option. Shown here is our package of 2 bolts and matching washers which are used to attach the thermostat housing (also called the water neck) to the water pump housing. These can also be used with either our billet aluminum or chrome steel fuel pump block-off plates.
The BETTER Option. Our ARP black oxide coated fuel pump blockoff plate OR water neck bolt kits are exactly what people mean when they say "show quality." Made from start to finish right here in Southern California, they are forged from aircraft quality 8740 Chrome Moly steel that exceeds the most stringent aircraft quality standards, and are rated at a minimum 170,000 PSI, which is even stronger than a grade 8 bolt! These feature a 12 point head. Matching black oxide washers are included. Small details like this can really make a car "show quality."These can be used with either our billet aluminum or chrome steel fuel pump block-off plates, or our billet aluminum water necks.
The BEST Option. Our ARP polished stainless steel Fuel Pump Blockoff and/or Water Neck bolt & washer bolt kits are exactly what people mean when they say "show quality." Made from ARP's proprietary "300" stainless steel alloy, they are rated at a minimum 170,000 PSI, which is even stronger than a grade 8 bolt! And, you can't beat the quality, shine and corrosion resistance of polished stainless. Nothing resists the ravages of weather, time and even repeated tightening and loosening like stainless. These are truly maintenance free! They also feature a reduced diameter 12pt head. Matching polished stainless washers are included. These can be used with either our billet aluminum or chrome steel fuel pump block-off plates, or our billet aluminum water necks. This is a great place to use stainless, since these bolts are very near the engine coolant, and this tends to be an area that is normally subject to excessive amounts of rust.
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.
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!
