Product Description
Michigan Motorsports LS1 Rocker Arms
with Trunnion Bearings Professionally Installed
No bolts are included in this kit. You will need to reuse your stock bolts or purchase bolts separately.
Fits all 4.8L 5.3L and 5.7L LS-based engines as well as Cathedral port 6.0L engines (LQ4/LQ9). Will NOT fit 6.2L engines or 2007-later 6.0L (L96, L92, LY6, LS3, L99, L76, L77)
Whether you have a stock LS motor or a highly modified LS motor, replacing your rockers with a true roller bearing setup is highly recommended. The stock bearings have a tenancy to fail. These rocker arms are a must have for any aggressive heads and cam combo. The caged roller bearings greatly reduce the possibility of the bearing failure experienced with stock LS1 needle bearings, which can send loose needles throughout the engine upon failure.
Fits all these applications: LS1/LS2/LS6/ LR4 Vortec 5300 LM7 L59 LM4 L33 – 4.8/5.3/5.7/6.0/ Engines
