Product Description
*** ONLY ONE AVAILABLE ***
NOS, never installed OBX LSD for use in A520 and A555 transmissions to build 5 speed transmission with a LSD differential. Does not require spacers, just normal shims to get your preload correct on the differential when installed in the case. If you want to build a hybrid A555 with this OBX, you will also need to source a A520 pinion shaft that matches the build date of your A555. There are 87-88 style and the 89, they are not interchangable.
This is a NEW OBX unit purchased from Turbos Unleashed ($550) and it has the upgraded TU hardware and clean up service already performed. Ready to be installed. Comes with two new Timken Set 11 bearings already pressed on and a 3.50 ring gear and bolts.
