1 x Set of B6-B7 S4 0A3 transmission to block bolts. **
1 x B6-B7 S4 0A3 transmission. (note, reuse 01E spacer and dowels.) Also the crank sensor needs to have the aluminum spacer removed that it originally had for the 01E)
1 x B5 S4 2.7t clutch and flywheel combo (Our performance options work very well with the 0A3)
1 x B6-B7 S4 shift rod setup (all 3). NOTE: The body does need clearancing for the B6 rods sometimes due to rods being shorter and sitting more forward in the car, also when using a JHM shifter it helps to clearance for the back two shifter assembly mount holes to access the bolts due to the spacers.
1 x B6-B7 S4-RS4 OEM or JHM shifter. These are clamp on knob, you can run B5-S4 or C5 A6-allroad 01E shifters but they must be 01.5 and up with an angled base, keep in mind the B6-B7 shifter is much better.
1 x B5-C5 plastic shifter box and boot only.

1 x B6-B7 S4-RS4 0A3 Passenger side front CV shaft shield.

2 x Driveshaft shield bolts. DRIVESHAFT AND REAR DIFF PARTS
B5 S4 = 1 x B5 A4 5-speed Rear diff- Diff code DAJ with 3.89 ratio to match B6-B7 S4 transmissions front diff ratio. NOTE: You MUST swap your B5 S4 larger 110mm output shaft flanges to the A4 rear diff with smaller 100mm flanges. This is just one bolt each and a good time to replace the seals and fill the rear diff with fresh fluid. All parts we stock.
C5 A6 = 1 x C5 A6 2.8L 5-speed Rear diff- Diff code EUT with 3.89 ratio to match B6-B7 S4 transmissions front diff ratio.
1 x ADAPTED 01E DRIVESHAFT (MAKE IT SHORTER BY 1.25" on the front side of the center bearing). Any good driveshaft shop can do this, expect to pay between $250 to $400 depending on your shop. This is because they need to cut the shaft, remove material and then rebalance both the front and rear sections. Keep in mind it is a great time to get a 034 driveshaft bearing from us, 2 x driveshaft boots (they are torn a lot which is bad for the joints) and or cv joints as needed to freshen it up and keep vibrations down. REUSE OR SOURCE THESE 01E parts if you do not have them.
