Connecting rods STDX Audi (2.5L) V5 TFSI Race Series ACL ACL-1B5562HX-STD

Audi STDX connecting rods (2.5L) V5 TFSI Race Series ACL adapt to high RPM deformation and assist in the formation of hydrodynamic oil films. This technology, combined with the advanced geometry of the bushings, makes them ideal for heavily stressed engines. Most bushings are also available in several other dimensions: STDXX -0.025 mm ( looser than nominal) STDX +0.000 mm (nominal) +0.025 mm (tighter than nominal) +0.25 mm (first shaft grinding) +0.50 mm (second shaft grinding)
