Frequently Asked Questions

What products from ARP are in this collection?
This collection groups ARP products around engine fasteners, studs and hardware for high stress applications, making it easier to shop that brand by application, fitment and build goal.
Is ARP a good choice for performance builds?
ARP is widely chosen for enthusiasts who want proven parts rather than guesswork. The right product still depends on your vehicle, power target and how the car is used.
How do I confirm ARP compatibility with my setup?
Check the product listing for vehicle, engine or universal fitment notes. For custom or high horsepower builds, confirm supporting mods, dimensions and connection types before ordering.
Do ARP parts need supporting upgrades or tuning?
Some do. Fuel, turbo, ignition, ECU and driveline parts often work best with the right supporting hardware and, where relevant, professional tuning or setup.
Why buy ARP parts from 1320 Motorsports?
We focus on proven performance parts for real builds, so the aim is to help you choose the right ARP product for your combination instead of piecing together a setup blind.
