Product Details

The ARP 655-4000 is a premium 5-piece hex bolt kit featuring specially alloyed ARP 300 stainless steel fasteners designed for automotive, marine, and trailer applications. These high-performance bolts are nominally rated at 180,000 psi tensile strength, providing a substantial safety margin over standard Grade 8 hardware.

Key Features:

  • ARP 300 stainless steel construction for superior strength and corrosion resistance
  • 180,000 psi tensile strength rating exceeds Grade 8 specifications
  • Specially polished finish provides excellent appearance and rust resistance
  • 12-point head design for improved grip and torque application
  • Includes matching washers for complete installation
  • Maintenance-free stainless steel requires no special care

ARP's premium fasteners are engineered for enthusiasts who demand reliability and durability in critical applications. The stainless steel construction ensures long-lasting performance even in harsh environments, while the polished finish adds a professional appearance to any installation.

Thumbs up

Simple order process.

Ok

Good seller, less expensive products compare to other online store, and fast shipping too, I ordered last Sunday July 29, and it will gonna be here tomorrow , so excited.. Highly recommended !

Great prices.

GOOD SERVICE, FAST SHIP, CHEAP PRICE

I ordered this product and Wednesday in the morning and it was on my door step Thursday morning with regular shipping. The ordering process was super easy and the price was $35 cheaper than any other online retailer. The Rack is awesome, easy to assemble took me about 20 minutes by myself, put on my jeep hooked up the bikes and off I went, fantastic design, I highly recommend the Rola NV2 bike rack and highly recommend Autoplicity

Not sure if they overlooked my order but I didn't get my shipping info (3 days after ordered) until I emailed asking for status update. I received a response the following day and all my items ordered came 2 days later...much faster than I had anticipated considering the "delay" or lack thereof (5 days total). Long story short...items are as described, best prices (from what I can researched online for same items/brand) and resonable shipping prices. the selection and brand(s) offered were somewhat limited for my specific needs, otherwise I would've ordered more.

I was trying to locate a hi volocity radiator fan and for it at Autoplicity at a very good price. The item was shipped fairly quickly concidering it most likely had to come from the manufacturer. Thanks for your help.
