ARP Fasteners: Precision Engine Fasteners for Canadian Performance Builds
The "Gold Standard" in automotive hardware. Engineered for extreme tensile strength and unmatched reliability, ARP is the first choice for Canadian mechanics and performance enthusiasts building high-horsepower engines.

When you are pushing the limits of a turbocharged diesel, a high-revving import, or a classic V8 muscle car, the only thing holding your engine together under pressure is its fasteners. Standard OEM bolts are often designed for daily commuting, not for the massive cylinder pressures and thermal expansion of a performance build. This is where Automotive Racing Products (ARP) comes in.
Founded in 1968, ARP has spent decades perfecting the art of the fastener. Today, their products are found in everything from NHRA top fuel dragsters to Formula 1 cars, and most importantly, in the garages of Canadian builders who refuse to settle for second best. At SHDP, we supply Canada's engine builders with the genuine ARP hardware required to ensure their projects survive the track, the trail, and the street.
The Science of Clamping Force
What makes an ARP fastener different from a hardware store Grade 8 bolt? It starts with the metallurgy and ends with a manufacturing process that is second to none.
Superior Materials
ARP utilizes several proprietary and high-grade alloys depending on the application:
- 8740 Chrome Moly: Rated at 190,000 psi. The industry standard for high-performance head studs and main bolts.
- ARP2000: Capable of 220,000 psi. Designed for heavy-duty diesel and forced induction applications.
- Custom Age 625+: A super-alloy with 280,000 psi tensile strength, essential for extreme boost levels.
- Stainless 300: Polished, rust-proof, and rated at 170,000 psi—perfect for show-quality engine bays.
Advanced Manufacturing
Unlike mass-produced bolts, ARP fasteners are:
- Thread Rolled After Heat Treat: This process is 10 times more fatigue-resistant than fasteners threaded before heat treatment.
- Centerless Ground: Ensures perfect concentricity for even load distribution.
- Shot-Peened: Increases the surface integrity and durability of the material.
- Quality Controlled: Every piece is inspected to tolerances as tight as 0.0001mm.
Essential ARP Kits for Your Build
SHDP stocks a wide variety of ARP fasteners tailored to different areas of your vehicle. Whether you are doing a top-end refresh or a full rotating assembly balance, we have the hardware you need.
1. Cylinder Head Studs & Bolts
Head studs are the most critical upgrade for any performance engine. Unlike bolts, studs provide a more accurate torque loading. Because the stud remains stationary while the nut is tightened, the fastener is subjected to only tension rather than both tension and torsion. This results in superior head gasket sealing—a must-have for boosted applications.
2. Main Stud & Bolt Kits
Keep your crankshaft exactly where it belongs. ARP main studs prevent "main cap walk," which can occur under high RPM and high load, leading to catastrophic bearing failure and block damage.
3. Connecting Rod Bolts
The rod bolt is the highest-stressed fastener in your engine. It must withstand the violent forces of the piston changing direction thousands of times per minute. Upgrading to ARP rod bolts is the cheapest insurance you can buy for your bottom end.
4. Driveline Hardware
Don't let a sheared flywheel bolt ruin your day (or your transmission). ARP offers high-strength flywheel and pressure plate bolts that handle the shock loads of aggressive shifting and high-torque launches.
Specialized Diesel Fasteners for Canada's Workhorses
Canada is diesel country. Whether it’s a high-torque Cummins towing through the Rockies or a Duramax built for the drag strip, diesel engines face unique challenges. With massive compression ratios and high boost pressures, OEM head bolts often stretch, leading to "blown head gaskets."
ARP’s heavy-duty diesel head stud kits (especially in ARP2000 material) are the industry-recognized fix for the Ford Powerstroke and other diesel platforms. By replacing factory TTY (Torque to Yield) bolts with ARP studs, you provide the clamping force necessary to hold the cylinder head down under the most demanding conditions.
Buying Guide: Choosing the Right Fastener
Studs vs. Bolts
If you are building an engine for maximum reliability and plan on potentially taking it apart for inspection later, Studs are the superior choice. They protect the threads in your engine block and provide more consistent torque. Bolts are excellent for tight clearance areas where you cannot slide a cylinder head over a pre-installed stud.
The Importance of Lubricant
Never install ARP fasteners "dry" or with standard engine oil. Use ARP Ultra-Torque Fastener Assembly Lubricant. Friction can account for up to 90% of your torque reading. Using the correct lubricant ensures that you achieve the exact required "preload" (fastener stretch) every single time, preventing uneven clamping force across the head.

Frequently Asked Questions About ARP Fasteners
Yes. Unlike factory Torque to Yield (TTY) bolts which stretch permanently and must be discarded, ARP fasteners are designed to be reusable. However, it is important to measure their "relaxed length" to ensure they haven't been stretched beyond their yield point. If they meet the original spec, they can be reinstalled multiple times.
8740 Chrome Moly is rated to 190,000 psi and is suitable for most performance applications. ARP2000 is a more advanced alloy rated to 220,000 psi, offering higher resistance to hydrogen embrittlement and better performance in ultra-high-boost diesel and drag racing engines.
For most applications using ARP Ultra-Torque lubricant, a re-torque is not strictly required. However, many professional engine builders still recommend a heat cycle and re-torque for high-performance head gaskets (like MLS gaskets) to ensure everything has settled perfectly.
We ship fast and hassle-free to all provinces. Whether you are in a major hub like Toronto or Calgary, or a more remote location, we use reliable carriers to ensure your performance parts arrive safely and on time.
