    Product Description

    Michigan Motorsports LS1 Rocker Arms

    with Bronze Bushing Style Trunnion Upgrade Installed

     Whether you have a stock LS motor or a highly modified LS motor, replacing your rockers with upgraded Trunnion Kit 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. 

    LS Rocker Arms feature our BUSHING TRUNNION KITS. The bushing bearing operates smoother and can operate at a higher RPM than even the caged bearing style upgrade. The bushing design provides superior lubrication to the trunnion while also providing maximum load capability. Our innovative design prevents premature failures caused by the weak O.E. or replacement needle bearings, eliminating the possibility of debris from a bearing failure that can cause severe engine damage.

    Our special C932 bushing material is bathed in oil via grooves at 2 different locations on the trunnion. These channels constantly feed oil to the bushing surface ensuring proper lubrication. The greater surface of our bushed trunnion will support 300 times more load than a needle bearing trunnion. Our bushing gets more lubrication and has less load applied to it than the bushing in the small end of a connecting rod, giving it long service life. 

    Fits all these applications: LS1/LS2/LS6/ LR4 Vortec 5300 LM7 L59 LM4 L33 – 4.8/5.3/5.7/6.0/ Engines

     Includes:

    16 New LS1 Rocker Arms with Bushing Style Bearing Trunnions Professionally Installed and 16 Allen Head Bolts.

      rocker arms

      Posted by Anthony Rich on Aug 4th 2021

      Fits my LS4 engine nicely no needle bearings to fall into the engine was going to use the caged bearings rocker arms but after this guy showed me a LS engine were a needle bearing fell into the engine it welded the camshaft to the engine block I figured for 80 dollars more I have more peace of mind.
