LIC Motorsports Pinned Mains (EJ25)

Item # LIC 515000

We now offer pinned mains on cases as an option on bigger builds. This isn't something that is necessary for everyone but anyone over 400whp and 25psi of boost, its something that should at least be considered.




What does this do and why would I need it?

The issue at higher horsepower and boost levels is what's called shuffling. This is where the two blockhalves come together, it literally starts to move around, this is caused by pressure/heat/torsional stresses/etc.

By pinning the mains (aka anti-shuffle pins) a more robust and rigid environment is achieved. This custom pinning work can now be done through LIC Motorsports.


Turnaround Time: 2 weeks (once in the schedule)


Additional Notes:

  • Contact LIC Motorsports prior to shipping
  • Line hone will need to be done after pinning process
  • Customer must provide good/useable case halves
  • Shipping to LIC Motorsports arranged by customer
