To prevent this from ever happening, conscientious engine builders rely on ARP’s “bulletproof ” alternator studs. They’re made from a premium grade 8740 chrome moly steel alloy and heat-treated to a nominal 190,000 psi tensile strength. They are very rigid and won’t bend under the stress of competition, eliminating problems with alternator pulley alignment. Here’s more reliable “insurance” from the innovators at ARP. Available in 5.000˝ and 5.250˝ lengths. Includes a 12-point nut and flat washer. ALTERNATOR STUD KITS Application Part No. CHEVROLET Small block (up to 1996) 134-7901  l Big block 135-7901 s Big block (+0.400 tall deck) 135-7902 s FORD 239-312 Y block 154-7906  l 289-302 cid & Boss 302 154-7904  l 351W 154-7901  l 351C, 351-400M 154-7905  l 390-428 cid FE Series 154-7902  l 429-460 cid 154-7903  l OIL PUMP DRIVESHAFT KITS Many an engine has been destroyed as a result of oil pump driveshaft failure. To cure this all-too-common problem, ARP has designed an extra heavy-duty shaft that will provide you with the necessary reliability. The shaft is made from heat-treated, premium grade aerospace chrome moly steel. Moreover, the shaft diameter is a larger diameter than the OEM unit. These features combine to enable ARP shafts to handle the added torque requirements of increased capacity oil pumps or heavy viscosity lubricants. CHEVY DRIVES: Made from premium grade 8740 and heat-treated to 190,000 psi , ARP uses a unique manufacturing process where the alignment sleeve is roll formed onto the shaft (not welded or pinned), enabling the sleeve to float, allowing for slight misalignment. FORD DRIVES: Made from ARP2000 and heat-treated to 220,000 psi . These pump drives feature a CNC milled (not broached) hex, and has the retaining washer installed. IMPORTANT NOTE: Make sure you ALWAYS check clearances: shaft to block and pump to distributor.
