PLM Header Assembly Hardware Kit

Fitment:

  • PLM Headers that utilize slip-fit collectors
  • B-Series, K-Series, D-Series
  • Replacement for all stock hardware to screw in studs with machined nuts

Kit Includes:

  • 2 bolts
  • 2 nuts (4 nuts for the long version)

 Features:

  • 8.8 grade or higher quality bolts
  • Direct replacement
  • Short bolt is 2 3/8" inches in length
  • Long bolt is 3 1/2" inches in length

Which one do you need, short or long?  Most PLM headers utilize the short version.  Once the slip-fit collector is fully inserted, the short version hardware fits perfectly.  On rare use cases, such as the H-Series Ramhorn header, where the 4-1 merge collector needs more adjustability, you will need the long version to allow more play in the slip-fit collector.

Sebastian W. ★★★★★

These bolts and nuts feel way more solid than the stock pieces I pulled off my B-series, and the slip-fit collector fit was spot-on. Swapped out all the old hardware in under an hour, no stripping or wobble.

Claire N. ★★★★★

The machined nuts in this kit actually torque down smooth instead of fighting me like the old ones did. Everything lined up with the slip-fit collector on my header without any wobble.

Emily X. ★★★★★

Swapped out the rusty factory studs and nuts on my slip-fit header with this kit and everything threaded on clean with no cross-threading. The machined nuts seat nicely against the flange, which fixed the small leak I had at the collector.
