Connecting Rod
(Toyota Journal / Chromoly H-Beam)
Are you about to rebuild your 20/22R/T/E power plant and would like to have something between stock rods and hardcore crossbeams? How about a set of forged H-beams for well under $400? After a couple of decades dealing with different H-beam connecting rods we decided to start making our very own rods, setting a new industry standard and at a very attractive price! LC Engineering’s H-beams are your best option for either rebuilding your performance engine with up to 600HP or just replacing your worn out stock connecting rods on your daily driver.
The LC Engineering H-Beam 4340 Forged Chromoly Steel Connecting Rods are manufactured from a two-piece forging process. This process forces the grain into the shape of a connecting rod, resulting in superior fatigue life. The rod cap is forged separately so that the grain runs perpendicular to the load forces which further strengthens the rod.
LC Engineering rods include a higher content of nickel & chromium, which increases the strength & fatigue life without making the rod brittle. Every rod is shot peened to stress relieve the metal. LC Engineering x-rays, sonic tests, and Magna-fluxes each rod to ensure quality. Every LC Engineering rod is multi-stage heat treated and includes 7/16" ARP 8740 bolts which can handle up to 210,000psi. Silicon bronze bushings are inserted for a floating piston pin.
The last step before each set is cased is they get bundled in weight-matched sets within 5 grams! The LC Engineering H-Beam connecting rods are 86 grams lighter per rod than a stock Toyota connecting rod. When thinking of that in grams it may not seem like very much, but when you add it all up that’s a 3/4 pound reduction in rotating mass. Less rotating mass means quicker throttle response, faster revving and less wear to the bearings and crankshaft.
LC Engineering’s rods are ready to run; installation instructions & bolt lubricant are included. Complete set of 4 rods, includes ARP rod bolts and Moly Lube.

NOTE: These rods have the Toyota Journal and made to fit the stock Toyota Crankshaft. These rods have bearing tang on one side only like the factory rods.When installing these connecting rods, LC Engineering recommends following the direction of the “Original†tang orientation from Toyota and all should face the drivers side of the block.

Disassembly Notes:
- Always disassemble and thoroughly clean all rod bolt surfaces. Do not use metal stamps to number rods, Felt tip markers or tool maker's dye are an excellent alternative.
- Rod bolt threads and underside of head of the bolt should be lubricated with ARP Moly
Assembly Lube. Do not use oil or Loctite. Cap should be seated on rod by aligning cap by
hand and lightly tapping into place. Alternate tightening bolts to avoid cocking cap.
- If any other lubricant is used on bolt, bolt stretch method must be used due to different
Viscosity lubricants. Improper bolt torque will cause premature bolt failure.
- Rod bolts are manufactured from high grade steel and are vulnerable to corrosion. Care should
be taken when handling fasteners to prevent exposing to moisture. Bolts should be handled
by the bolt head. Bolts should always be lubricated prior to handling or storage.
Disassembly Instructions:
For disassembly break bolt loose ¼ turn each rod bolt alternating sides until loose.
To accurately determine the life of a bolt, it is recommend that a log of the bolts original free-standing
(un-torqued) length should by kept and recorded upon subsequent tear downs for inspection. The
freestanding length should be checked against its original length. If there is an increase of .001" or more,
or if there is any permanent deformation or galling, the bolt should be replaced.
Reassembly Instructions:
When installing these connecting rods, LC Engineering recommends following the direction of the “Original” tang orientation from Toyota (which are all located on the drivers side of the block). On Part# 1013198 (Toyota Journal Rods) the LC Engineering logo will face the rear of the block.
NOTE: (22 Stroker) You must always check engine clearances when changing internal engine components! The
oil galley may need to be clearanced on some applications. You should have a minimum of .030”
clearance between the rod bolt head and the block.
Clearances:
Listed below are typical clearances and will vary according your application. Refer to
manufacturer's specifications for your application. See Factory service manual.
Do NOT modify rods or rod bolts for clearance.
Rod bearing oil clearance: - .0015"-"0035"
Piston pin clearance: - .0005" - .0015"
Rod side clearance (single rod journal): - .007"-.020"
Rod-to-block: - .030" minimum
Wristpins:
Bent or out of round wrist pins will cause deformation of pin bores. Check your pins! We do
not recommend the use of pins of less than .110” wall in normally aspirated engines and
.150” wall in forced induction applications. These are minimum wall requirements for
Chrome Moly or equivalent materials. We can sell you pins if needed.
