  • Will not fit 2007-later models of 6.0L. Will not fit 6.2L.
  • Michigan Motorsports' billet LS rocker stands are an excellent upgrade for your valvetrain. CNC Machined in the USA from 6061 Billet Aluminum, these stands offer improved rigidity and reduced flex compared to the OEM stands, as well as more consistent rocker saddle heights.
  • The OEM GM stands can vary as much as .015", making it difficult to set consistent lifter preload heights especially when dealing with short travel aftermarket lifters. The rocker heights on these billet stands are true within .001" over their full length. Replaces GM # 12552203.
