3RZ Pro Piston & H-Beam Rod Set Low Compression (8.3:1) 1995-2004
If your 3RZ is turbocharged or supercharged, high boost levels can wreak havoc on your stock internals.The factory crankshaft is excellent, but the factory connecting rods and pistons can be a problem with high boost levels. Avoid the costly damage in the future by upgrading the weak points in your 3RZ with this LC Engineering forged rod and piston set. This package includes a set of our forged 8.3:1 (+.020 over) 95.5mm low compression pistons to drop your compression ratio so you can raise your boost level safely. Will also include a set of gas nitride piston rings to help keep the boost in the combustion chamber. A set of custom chromoly H beam connecting rods that are much stronger than the factory rods. We also include the rod bearings you will need to tell us what size you need. Bearings come in standard, .25 .50 or .75. This package is an excellent way to add the needed strength and reliability to your high performance 3RZ.

CP pistons come with a top ring that is a steel compression ring that has been gas nitrided so that it is compatible with Nikasil and cast iron bores. This scuff resistant gas nitrided ring allows it to operate at maximum efficiency without blemishing up the bore. The nitriding ensures extended life and protection under extreme conditions. The second ring is a cast iron with a taper underhook groove face. The ring acts as a wiper and pushes the oil back away from combustion. This type of ring allows you to run a lower tension oil ring. The oil ring is made up of two gas nitride rails with a low-tension expander. Because of the miniflex vent design; there is less friction on the cylinder wall, which increases the performance and efficiency of the engine. These ring sets are high strength and low tension, resulting in maximum sealing with minimum drag.
H-beam connecting rods are made from 4340 steel, x-rayed, magnafluxed, sonic tested, and shot-peened to ensure optimal quality and strength. They are packaged in weight-matched sets that are within +/- 1 gram end to end. The connecting rods for Toyota 3RZ undergo a 2-piece forging process and are machined in the USA. Rods will include ARP 8740 rod bolts for extensive ability to handle power and boost.
