Arlows 4x Steel Connecting Rod 150mm Mitsubishi Lancer Evo 4 - 9 4G63 ( H-Beam )

Mitsubishi Con-Rod Set

Fitting at Mitsubishi 4G63 engines of the 2nd generation!

This highquality con-rods are made of 4340 steel (40CrNiMoA).

Con-rods with the I-shank are the strongest and most resistant rods at all.

That's why these I-shank rods also get used by US-Dragster and Formula 1 Racecars.

The structural analysis of the I-shank shows, that it can absorb the most axial section modulus without deforming.

They're perfectly suited for high-power engines.

At first this con-rods got many times hardened to achieve an durability of HRC35-38.

Finally they got shot-blasted to strenghen the surface density to the maximum.

Before all of our con-rods are 3D designed and finally CNC-milled, it's possible to simulate a lot of charge states and tensions.

The small-end-bearing is made of bronze, and is suited with an lubrication bore.

The special thing about this "Pro"-Version is, that it is suited with an oil rise bore. This oil rise bore provides the piston pin with fresh oil.

All our connecting rods are equipped with high-strength Pro-Series 14.9 screws ! These have a tensile strength of 1490N/mm^2. Furthermore, the threads are rolled which also increases the flank thickness by 30%.
