™ Because races can be won or lost in the pits, the engineers at ARP set about to create the ultimate oval track competition wheel stud that facilitates accurate wheel positioning and quicker release/tightening of lug nuts. ARP’s new “Speed Studs” (and companion “Speed Nuts”) are so good that a large number of Nascar teams in Monster Energy Nascar Cup, Xfinity and Camping World Truck Series use them exclusively. They’re made from heat-treated 190,000 psi chrome moly steel and feature precision J-form threads (formed after heat-treat for improved fatigue strength), exclusive nut-starter and bullet shape radius that all but eliminates cross-threading, shot-peening, special baked-on dry film lubricant (reduces possibility of galling and assures consistent clamp loads), and double magnaflux inspection. A new head design is employed that fits the registers of all popular hubs without grinding, and studs are available in 31 underhead lengths to provide you with the optimum thread engagement for your particular setup. The finest studs available!  Note: All Speed Stud™ applications fit Stock Car Products and Speedway Engineering Hubs without grinding or modifications. |

| Designed for professional racing environments where split-second improvements in pit stop times can make the winning difference, and “unbustable” reliability is an absolute must. ARP’s Speed Nuts feature a profiled nut face for easy installation, quicker socket releases and resistance to jamming. They’re made from premium heat-treated chrome moly that’s nominally rated at 190,000 psi tensile strength, shot-peened to remove stress risers and double magnafluxed after heat-treating and thread-forming to assure 100% metallurgical integrity. Coated with Alumotef III gold coating. Speed Nuts are ready for “instant” use (thread chasing not required). |
|
| Not only will these premium quality ARP fasteners help prevent intake manifold leaks, but one is drilled to allow for a seal wire. What’s more, they’re nominally rated at 180,000 psi and feature precision rolled threads for optimum engagement, to prevent galling and promote more consistent torque loading. Wide underhead flange design and companion flat washers provide even load distribution and facilitates optimum sealing of gasket surfaces. Made of corrosion resistant stainless steel. Washers included and bolt drilled for NASCAR inspector’s wire seal. |

The best way to make sure that carburetors stay perfectly sealed to the intake manifold is through the use of ARP’s carb studs, which feature J-form threads to resist loosening from vibration. They’re offered in a variety of heights to accommodate most any combination of carb and spacer, and are available in 8740 chrome moly with a black oxide finish. Special NASCAR type studs have one of the studs drilled to facilitate sealing the carb by race officials. All carb studs include a nut starter nose (except where noted) and kits come with hex nuts and washers. |

| Strange as it may seem, there have been many races lost in oval track, off-road and endurance competition due to the OEM alternator stud failing and the subsequent loss of electrical power. 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 5.000½ and 5.250½ lengths. Includes a 12-point nut and flat washer. |

| It’s a proven fact that OEM head bolts are the weak link in a diesel engine; especially if the engine has been modified. That’s because Chevy Duramax, Dodge/Cummins and Ford Power Stroke engines are all assembled using “Torque To Yield” (TTY) bolts and preloaded to yield and beyond (typically 100-110%). Any increases in combustion pressure can lead to problems like blown head gaskets or catastrophic engine failure. And because TTY bolts are yielded by design, they should never be re-used.= ARP solves the problem by offering stronger head studs that are designed for higher clamping loads. They are available in several different strength materials to safely handle applications from performance street to all-out competition. Similar improvements over factory TTY bolts are provided by high strength ARP main studs. And there’s more. With increased performance you need the extra security that ARP flywheel and flexplate bolts can provide. Given the growth in extreme diesel competition and street add-ons, ARP is continually developing additional diesel kits.

We highly recommend using a stretch gauge when installing rod
bolts and other fasteners where it is possible to measure the
length of the bolt after tightening. It is the most accurate
way to determine the correct pre-load in the rod bolt. Simply
follow manufacturer’s instructions, or use the chart on
page 30 of this Catalog. for ARP fasteners. Measure the fastener
prior to starting, and monitor overall length during installation.
When the bolt has stretched the specified amount, the correct
preload, or torque, has been applied. We recommend you maintain
a chart of all rod bolts, and copy down the length of the fastener
prior to and after installation. If there is a permanent increase
of .001" in length or more, or if there is deformation,
the bolt should be replaced immediately. Don’t chance it!
A sample chart is as follows: ARP offers a highly accurate stretch
gauge with a dial indicator that reads in increments of .0005".
Features extra heavy springs for consistent repetition. Comes
with a heavy-duty, insulated plastic carrying case for protection.
A “must” for any serious engine builder. Product ...............Part # Stretch Gauge 100-9941 $340.56 Stretch Gauge, billet-style 100-9942 $255.08 Stretch Gauge, digital 100-9943 $858.13 |

ARP ROD VISE |
Professional engine builders know that the best way to correctly
install connecting rods is to resize the rods prior to installing
them on the crankshaft. This involves installing the rod bolts
using ARP Ultra-Torque and the correct stretch or torque value
for your application. Once the rod bolts are properly installed,
the rod journal is measured and machined to the proper size and
tolerance providing correct bearing and oil clearance. ARP’s
anodized aluminum rod vise securely holds the connecting rod
while the bolts are being installed - without damaging the rod.

By allowing you to consistently position spark plug ground electrodes
out of harm’s way, the ARP indexing tool takes the guess-work
out of installing spark plugs where the combustion chamber and
high dome piston clearances is critical. Designed to fit in the
palm of your hand, this tool eliminates the need to perform cylinder
head calibration. Best of all, the ARP indexer is made from aluminum
alloy with precision machined threads that allows you to proof
the quality of spark plug threads before installation in expensive
cylinder heads. Anodized for protection and quick recognition.
For use with tapered gasket 14mm plugs.

Those first moments an engine runs prior to building oil pressure
are when damage can easily occur. ARP’s Oil Pump Primer
Kit lets you spin the oil pump with a drill motor and bring up
the oil pressure prior to starting the engine. This prevents
any unnecessary wear or damage to rotating, reciprocating and
valve train components. ARP’s rugged primer shafts are rated
at 170,000 psi to ensure extended service life of this valuable
tool. They feature a special billet aluminum sleeve that accurately
positions the shaft and keeps it from |
