Product Details

The Hedman Hedders 69520 is a mid-length engine swap exhaust header designed specifically for installing a Small Block Chevy 283-400 (Gen 1) V8 engine into 1982-2004 Chevy S10/Blazer and GMC S15/Jimmy 2WD trucks. These headers deliver significantly more low and mid-range power than factory cast manifolds while providing better ground clearance than long tube headers.

Key Features:

  • 1-1/2 inch primary tube diameter provides optimal exhaust flow for transplanted SB Chevy engines
  • 2-1/2 inch ball and socket style collector (gasketless design allows for exhaust system misalignment)
  • 18-gauge mild steel construction with CNC mandrel bent tubes
  • Hand-welded for consistent pair-to-pair quality
  • 5/16 inch (0.3125 in) thick flanges for leak-proof seal
  • Compatible with both manual and automatic floor shift transmissions
  • Works with air conditioning and power steering equipped vehicles

What's Included: Headers (sold as pair), gaskets, header flange bolts, ball and socket reducers (exhaust adapters), and collector bolts. No collector gasket needed. Ships uncoated with temporary black paint that will burn off during initial use. Recommended to be installed with Trans-Dapt motor mount kit #9906. Backed by limited lifetime warranty. Made in USA since 1954.

Note: For 2WD applications only. Not legal for street use on 1975 and later vehicles—off-road and racing use only.

Great prices at unbeatable prices! I'm a happy customer so far.

Fast shipping. Order came within 3 days

Good information quick check out

Had a good experience. No proplem

VERY PLEASED AND IMPRESSED WITH THE SIMPLICITY OF YOUR ORDERING PROCESS

The product was exactly as advertised! Thank you for keeping the product price and shipping costs so low. You beat the competitors hands down for the same exact product. It was a pleasure doing business with you! You bought yourself more positive advertising than money can buy! Thanks again. Lou

Received the product but realized it was wrong size. Still waiting on response back in regards to exchanging for correct item.

First off, I LOVE my new shipments! These guys had everything at super low prices, and the shipping was phenomenally fast. It's all working great, and imm definitely buying from these guys again.

Good price, shipping discount--does not match what Google sees, but ok.

Great service. Shipped out the day after I ordered it...plus it was the cheapest of the competition.

I bought a Motive pressure brake bleeder from Autoplicity. I have been looking around for different prices for quite a while, and their price, even with shipping cost, was the lowest. After ordering, I received a notification of shipment and tracking number. The item arrived well packaged, complete, and intact within a few days. I am looking forward to using it.

Cheap prices, great quality, and fast delivery. Autoplicity will continue to receive my patronage.

Easy and fast. Order arrived very fast. Thanks.
