Far superior to any other main bolt kit offered for use in competition engines, ARP's High Performance Series main bolts are designed to meet the exacting standards and demands of professional engine builders. Forged from 8740 chrome moly, these bolts feature generous under-head radius and rolled threads for the utmost reliability. The threads are rolled after heat-treating, so their fatigue life is about 1000% longer than most main bolts that are threaded prior to heat-treating. With a nominal rating of 180,000 psi, these bolts are a premium replacement for OEM fasteners, and the kit comes complete with parallel-ground and hardened washers.

  • 1000% longer fatigue life than most other main bolts
  • Rated at 180,000 PSI, which is considerably stronger than Grade 8 hardware
  • Forged from 8740 chrome moly steel, with generous under-head radius and rolled threads
  • Designed to meet the exacting standards and demands of professional engine builders
  • High Performance Series main bolts are a premium replacement for OEM fasteners

Best prices online! Ordered a JBA performance exhaust and Airaid intake system for my 06 F-150. Was hesitant at first because I never heard of them but ordering was a breeze and saved me over $100 total for two items compared to anywhere else. Had package at my door in about 24 hours and even selected normal UPS ground shipping. Very satisfied and will definitely return!

Autoplicity was plenty cheaper than competitors for the springs I needed. I was shopping around and left the website after beginning a transaction and they sent me a coupon for 25% off shipping if I would return and purchase from them, which was cool. Unfortunately the coupon code didn't change the price and I didn't receive 25% off, but it was still cheaper than others.

Autoplicity gave me prompt notification both when my order was processed and when the order shipped.  The price was the best I could find anywhere, and several good reviews made me confident in my choice of stores over other stores who were charging more.  Thanks, Autoplicity!
