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.

  • 5/32" Hex broach on the top of the stud for ease of installation
  • Dog point design for superior preload
  • Oversized forged 13mm 12-point nuts and hardened parallel ground washers for superior load distribution compared to the smaller 12mm nuts and washers most use

Love how it looked
Purchased in 12/2024. Wore it every day without taking it off. Its coating has worn off on most of the bracelet now but I still consider it got my "moneys" worth from it. Took it off 4/25/26

I wish I could still wear it.
I liked the look and style of this bracelet. I had many compliments when I wore it, but about one month later the base of the clasp started to split open. What a waste, it is a beautiful bracelet.
