SpeedFactory Racing 4140 Head Stud Kit for Honda D-Series Engines

Description

We are proud to introduce our new D-Series Head Stud Kit that fits all variants!

No more having to mix and match fasteners for various block and head combos - our unique stud design fits all of them. Any combination of D15 or D16 block or head, non-VTEC or VTEC, D16Z6 or D16Y8 heads or blocks, etc. 

The SpeedFactory Racing 4140 Head Stud Kit is great for most forced induction applications up to 600+HP and includes oversized forged nuts & washers for superior load distribution.  This stud kit has been real-world tested to 750whp in an o-ringed & sleeved block with no issues.

A hex broach is incorporated on the top of the stud for ease of installation and a dog point end seats the stud in the block and preloads the fastener for consistent & accurate torqueing.
