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 and are the same rockers we utilize on
our 1,000 hp Turbo Motor. We utilize LS rocker arms and install new LS1 rocker arm
retro-fit
trunion kit that replaces the cageless, loose OEM needle bearings and
powdered
metal trunion with a premium 8620 steel alloy trunion and caged roller
bearings
for added durability. The caged
roller
bearings that 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
