Signature Series Connecting Rods
Direct Replacement 4340 Alloy Rods are Sonic-Tested and Mag Particle Inspected
Lunati has taken the wraps off its all-new 4340 alloy
steel Signature series connecting rods.
As direct replacements for their successful FM (fully machined)
series, these new race-ready I-beam
forgings are 100 percent sonic tested and Magnaflux inspected. In addition,
they are manufactured to extremely close tolerances (.0005˝ between centers), weight-matched
to plus-or-minus 1 gram, and heat treated to 28-30 on the Rockwell C scale. They
are made to the most precise standards Lunati knows and are available in sizes
from 5.4˝ to 6.4˝.
Precision-machined and with close attention to detail
these aircraft-quality mill-certified connecting rods are ideal for use in
circle track, drag race, off road or marine applications. Indeed, they suit all
naturally aspirated and forced-induction engines that are subjected to high
engine speeds and stresses.
Lunati, a specialist in competition connecting rods
for over 20 years and a supplier to the NASCAR scene for the past five, has
successfully tested the new Signature series in NASCAR competition during the
course of the past year.
Derek Scott, head of the Mississippi-based camshaft
and components firm, said the success of their existing FM series over the past
decade meant “we have hardly changed the rod’s material properties, but full
sonic testing has been hugely significant, guaranteeing increased strength and
eliminating risks of internal impurities—plus the rod’s precise tolerances are exceptional.
For 2.100˝ and 2.000˝ crankpins the Signature series
connecting rods are supplied with 7/16˝ bolts; for smaller 1.889˝ crankpins
(Honda journal) 3/8˝ bolts are provided. All bolts are of the ARP2000 series.
