Header Bolt Kit
12Point Head
16Pieces

ARP manufactures a variety of premium grade bolt and stud kits to facilitate installation of exhaust headers including the popular stainless stud kit with 12-point nuts. The Stainless 300 material is not affected by corrosion or extreme heat, making it ideal for the application. Whats more, the compact 12-point nut lets you easily slip a socket close to the pipe. Each ARP accessory stud or bolt kit includes the specific number of parts for your application, plus premium-quality washers and hex or 12-point nuts, as required. Studs are manufactured with a unique nut-starter nose that helps prevent cross-threading. Studs and bolts come either black oxide chrome moly or Stainless 300. Both are nominally rated at 170,000 psi tensile strength; substantially stronger than Grade 8 hardware. Specially drilled NASCAR models are available for those who wish to safety wire their header bolts to prevent loosening.

Special NASCAR model header bolts are available that are drilled for use of safety wire. Perfect for any racer who desires the ultimate in security. Available for small block and big block Chevrolet engines, plus many universal applications.

Great price

OVERALL EXPERIENCE VERY SATISFYING.

Everything went very well. Thanks for the opportunity to comment.

Great price and fast service

Haven't fitted them to my truck, my size is not listed on the bag but they are adjustable to a point.

easy shopping

I have ordered from Autoplicity several times in the past and I will continue to be a repeat customer.

Very simple checkout

I bought an Exedy Organic Clutch at the best price I could find. Shipping was also prompt. Legit dealer, good business.

Great Price!!<br>Fast Shipping!!<br>Would definitely use again....

Once i installed the BULLY DOG GT TRIPPLE DOG GAS TUNER PROGRAMER on my newerbody style 07 gmc sierra 1500, My mpg average went from 12 to 18. Instant improvement and performance. Not to mention the truck is lifted 7.5 in with 37 in tires. Easy programing settings takes minuets. The power the 5.3 puts out after my Bully Dog gas tuner was installed was fanominal. I will deff get my money back in fuel over about a year. Can't go wrong purchasing. This item. MUST HAVE PRODUCT.

Great deals at unbeatable prices!

Product was as described, shipping was fast, and communication was excellent. Plus I saved $$. Thanks Autoplicity! I'll be a repeat buyer and referral source.

Found a Thule Vertex bike hitch on here for $50 cheaper than amazon. Extremely fast shipping. Definitely recommend purchasing from here.

Great prices, reasonable shipping costs. Shipped within 3 days of order. Didn't receive discount for valid coupon code (25OffShipping). No response to 2 emails. No indication of expected delivery date. Lots of unknowns but you can't beat the pricing.

This was my first order with Autoplicity. I was pleasantly surprised when my order showed up quickly and was exactly what I wanted. I will be buying from this company again. Thanks for the quick service and fair pricing.

SO HAPPY! I have to admit, I was hesitant because I had never heard of autoplicity and there wasn't item a picture up for the Thule T2 rack I bought, but wow am I happy. Autopliicity had it for $100 less than other sites and the shipper was Amazon prime fast!!! Definitely a happy customer!!!!

I ordered a Thule 9002 Raceway Bike Carrier on Sunday, April 8 and received the product by Fedex on Wednesday, April 11 with just regular shipping. That is fast service. And the price was $43 cheaper than any other site on the internet (including shipping). I haven't had a chance to use the bike carrier yet but it appears to be new and as advertised with no issues as of this writing. I would definitely recommend this retailer for your next purchase.
