Who we are

Advanced Performance Industries

was created in 2018. After creating Josho’s line-boring in 2010, we realised the need for a high-quality cost-effective supplier of aftermarket pins & bushes to suit large hydraulic excavators. Working closely with customers to make modifications required to increase the pin & bush life. At API, we strive to supply high-quality carburised and Mn bronze bushes & induction hardened forged 4340 pins to suit large hydraulic excavators to achieve optimised performance & component life.

API Bushes

API bushes are case carburised using the same process and hardness as OEM bushes. However, the depth of hardness is up to 1mm deeper per side compared to OEM bushes. 

API have added an extra 5 grease holes in each bush and opened the holes up from 5mm diameter to 10mm diameter for maximum lubrication distribution. 

Cross hatching has been added for extra lubrication distribution. API have increased the interference fit to the outside diameter of some bushes to eliminate bushes walking out or spinning.

API 4340 Pins

API Pins are forged 4340 inductions hardened with 8mm side depth of hardness, by using the 4340 forged material it eliminates flexing/bending/snapping of pins, works especially well for the upper link pin on the 6060 which is renowned for bending/snapping.
