Description
Arlows 6x Steel Connecting Rod 148mm Toyota Supra A90 B58 (H-Beam)
Fitting at:
BMW 340i / Z4 - 3.0 24V Turbo (B58B30)
Toyota Supra - 3.0 24V Turbo (B58C30)
This highquality con-rods are made of 4340 steel (40CrNiMoA).
The H-shank enables maximum stability during minimum weight.
Thereby they're perfectly suited for high-engine-speeds.
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.
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%.
