Aluminum Roller Rocker Arms
 While
racing in SCCA Production classes during the early 1980's, we
recognized the need for quality aluminum roller rocker arms for
small displacement, high-revving Nissan/Datsun and Triumph engines.
To address this we set out to develop a rocker arm design that
lends itself to the most common ratios consistent with reliable
valve train geometry and modern camshaft designs. Our roller rockers
are bronze bushed and provide improved lubrication to the valve
stem tip as well as 360 degree pressure oiling of both the roller
tip and shaft surfaces. Rockers are sold in complete sets, mixed
ratios and individual replacements. (see
Tech Info for installation information)

| Notes: |
-
When ordering individual replacement rocker arms,
the part number must include the 3-digit ratio code and suffix I (for
intake) or E (for exhaust) and the cylinder number (1-4) to allow
correct identification of the required offset. Example: For a replacement
1.60:1 ratio exhaust valve rocker for No. 2 cylinder - order Part
Number 130-TRS-160E-2
-
INSTALLATION NOTE: When installing a new
set of rockers, we strongly recommend that a NEW rocker shaft and
NEW adjuster screws be installed to insure proper tolerances and to
reduce premature wear.
