Product Details

ARP manufactures premium-grade header bolt kits designed for secure installation of exhaust headers on performance engines. This kit is specifically engineered for Small Block Chevy Gen III LS Series engines with 1/4-inch wide header flanges.

Premium Materials and Construction:

  • Available in stainless steel or black oxide finish (8740 chrome moly steel)
  • Both materials rated at 170,000 psi tensile strength for maximum clamping force
  • Stainless 300 material resists corrosion and extreme heat
  • Black oxide chrome moly option provides excellent durability

Kit Specifications:

  • M8 x 0.984-inch bolts with hex head design
  • 12 bolts per package with premium-quality washers and nuts
  • Precision-engineered threads for consistent torque values
  • Compact design allows easy socket access near exhaust pipes

ARP header bolts eliminate the problems associated with inferior fasteners, including loosening from thermal cycling, corrosion, and inadequate clamping force. Each kit includes the exact number of components needed for proper installation. NASCAR-style drilled versions are also available for safety wire installation to prevent loosening in extreme racing conditions.

It was great!

Great experience purchasing my part. I just hope standard shipping will not take very long.

I didn't see an estimated ship/arrival time

I will be ordering from Autoplicity again

Website is friendly to mobile devices. Fast and confident shopping

Easy ordering, Fast shipping.

Best price for my brake pads and fast delivery.

all well

Not a bad experience. Wish the shipping time could have been shorter.

I did a search with the part number and decided to give your company a try.

Easy

East to find and purchase.

Great price and fast shipping, beat auto anything by a mile.

Thanks...hopefully they are shipped fast

Found the parts I needed for my vehicle's TPMS system that I could not get anywhere else. They were a better price than any of the other online stores and got my order shipped out in a timely fashion.

I was looking for a hitch mount bike rack for our bicycles. After doing a little looking around locally I found the exact rack I wanted at Autoplicity at a huge discount. It also shipped quickly, and I appreciate that.<br><br>Thanks!

Quick easy order

Autoplicity had the air filter I needed in stock when NO ONE else did. They responded quickly and got my order shipped. The only downside was that the shipping cost (regular shipping) was quite high compared to things I have ordered from other places. Still, total cost was comparable to what I would have paid if I purchased it locally.

1st time. OK

very good low price, had a slight issue but customer service was amazing,. i would recommend AutoPlicity to anyone because of that, good prices, good customer service,. (meaning trust worthy) why not :). A+++ Service will buy from again!

I found Autoplicity on a well known online vendor and the experiance was excellent so now I just go straight to autoplicity.com directly my last order (17805) was for some parts for my very modifide Jeep and two things stood out, the price and shipping, both were top shelf and above my expectations. Now when I need parts I check autoplicity.com first. They are my #1 now.<br>

I'm happy with my purchase and the service I received. I gave you guys a "good" rating instead of "excellent" on shipping only because I hate FedEx and would like to have another shipper option during checkout.

I purchased a Volant Cool Air Intake Kit for my truck. Autoplicity had the best prices by far! Shipping costs were very reasonable and my order shipped quickly. I'll order more from them in the future.
