Bolts & Fasteners

ARP Bolts

When racing professionals in NHRA, IHRA, NASCAR, and Formula 1 competition need bullet-proof fasteners for their high-performance machines, they turn to one company: ARP. Since 1968, Automotive Racing Products has been engineering and perfecting bolts, studs, nuts, and other fasteners for engines, cylinder heads, headers, wheels, transmissions, and more. ARP uses only top-quality materials—far above the usual “aerospace quality” others settle for—in a highly exacting manufacturing process to create fasteners with the strength and durability to last race after race.

ARP High Performance Series head bolt kits are tough. They are rated at 180,000 psi--15 percent stronger than Grade 8 fasteners. They come available with a reduced wrenching hex head or 12-point head that help eliminate the need for valvetrain removal when re-torqueing cylinder heads.

ARP High Performance Series main bolts are rated at 180,000 psi and a popular premium replacement for OEM fasteners. Designed to meet the exacting standards and demands of professional engine builders, ARP bolts are forged from 8740 chromoly steel and feature a reduced wrenching head, large underhead radius, and rolled threads for the utmost in reliability. The threads are rolled after heat-treating which gives them about 2,000 percent better fatigue strength than most main bolts that are threaded prior to heat-treating.

ARP Pro Series connecting rod bolts are precision CNC-machined to exacting specifications and designed for optimum reliability. They are heat-treated and threads are rolled to provide up to ten times more fatigue strength. This makes them far superior to standard OEM fasteners in terms of durability, and fully capable of handling the extra stress of high-combustion engines.

Camshaft

RV Camshaft

An RV Cam offers additional torque at low RPM. It's great for off-roading and towing but won't make much of an impact for things like highway driving. If you're planning on doing "Jeep stuff" then this upgrade is for you.

Our RV Cam has a Valve Lift of 420 vs the standard Cam lift of 408.

Connecting Rods

Forged Rods

The Scat Forged Connecting Rods are excellent at maintaining peak performance and handling increased pressure that engines experience when Super or Turbo Charged.

Crankshaft

Crankshaft Balance

The Balance Upgrade is a process of spinning the crankshaft to determine where adding counterweight would reduce vibration within the engine. This makes for a smoother and quieter ride across all RPMs.

Cylinder Heads

New Cylinder Head

We offer the option to upgrade to a brand new cylinder head which is based on the Tupy 0331 Head Casting.

New Cylinder Head with Large Exhaust Valves

We also offer the option to machine the New Head to fit larger valves. These larger valves offer better flow and improved performance.

Fuel Injectors

High Volume & Performance 24lb Fuel Injectors

The 24lb Fuel Injectors that we offer are STRONGLY recommended for keeping up with the flow demands of our Stroker Engines. These will keep your fuel flowing fast for maximum performance.

Freeze Plugs

Brass Freeze Plugs

Standard Freeze Plugs are made of steel and will rust if exposed to water. So if you're water cooling or are out hitting the mud or near the water you'll want brass plugs which do not rust.

Pistons

Forged Pistons

Our Forged Pistons are intended for Super and Turbo Charged Stroker Engines. These pistons are designed to take the extreme levels of heat and force that Hypereutectic pistons can't handle while also giving you maximum performance. Due to the level of care required these are generally not recommended unless you are Super or Turbo charging your engine.

Rocker Arms

Scorpion Rocker Arms

Scorpion Rocker Arms are precision ground needle roller bearings capable of handling up to 380 lbs of open valve spring pressure. These rockers reduce friction and noise which helps your oil temperature, distribution, and overall engine longevity thanks to their precision rocker ratio.
