FULL DESCRIPTION
Hot Rods Connecting Rod Kit 8621
The Hot Rods Connecting Rod Kit 8621 is engineered for demanding applications, providing a durable and reliable replacement part. Constructed from hot-rolled ASTM 4115 material, these connecting rods undergo a case-hardening process to achieve a hardness of 58-62 Rc, ensuring exceptional strength and wear resistance. The innovative design incorporates side scalloping and vent slots, which are crucial for minimizing distortion in the bearing races at high RPMs.
Further enhancing its robustness, the rods are double-forged to optimize grain flow and ensure consistent dimensions. They are also shot-peened and double-honed, making them highly capable of withstanding significant loads. The small ends feature double-drilled holes to improve lubrication and cooling for the wrist pin bearing, a vital feature in high-stress environments. For superior performance and reduced friction, the included thrust washers and crank pin bearings are finished with a silver coating.
