Final Drive, Ring and Pinion General Rules
Standard / General rule R&P for unmodified gearboxes are as follows:
– 4.375 T1 (1200-1300cc Gearboxes)
– 4.125 T1 (1300-1500cc Gearboxes (Also Most Split Screen Reduction Box Units))
– 3.880 T1 (1600cc Gearboxes)
– 3.440 T1 (Never originally available, reproduction only)
Note: Reduction box combinations will reduce final drive by ratio, check your year and ratios to calculate.
– 4.571 T2 (082, 091 Boxes) Some 5 and 6 Rib Only
– 4.857 T2 (Oddball Year)
– 5.375 T2 (1600c T1 Engine Bay Windows)
4th Gear standard Ratios
Gears in certain cases can be crossed between boxes, note: currently keyed shaft boxes have no available new R&P combinations since Brazil ceased production, all current final drive sets are splined (late) only. Higher values produce higher acceleration, lower values produce higher top speed.
– 0.91
– 0.889
– 0.821
– 0.770

Gearbox Ribs Explained (Applicable to T2 Bay Window Gearboxes only, does not work for T25 Vanagon).
If you are unsure if you have a T2 Bay Window Gearbox, it is easy to tell by where the gear linkage comes out. On a Bay Window Gearbox it comes straight out the back (opposite end to the bellhousing). If it is a T25 box it will come out of the side on the nosecone.
1600cc – 3 Ribs 1700cc – 5 Ribs 2000cc – 6 RibsNote: The terms 002 and 091 gearboxes comes from the first 3 digits on the code found on the underside of the gearbox.
There were at least twelve variations of gearbox for the 1968-71, 1972-75 & 1976-79 VW 1600cc Type 2s, including many combinations of limited-slip differential and higher final-drive ratio for mountainous territories.
The CE code, corresponds to a 1972-75 VW T2 Bay Window, with standard open differential and standard final-drive ratio
There were two manual gearbox codes for the 1974-75 VW 1800 Type 2 (Type 4 Engine):
CM – Standard open differential
CN – Limited-slip differential (LSD)
Please note: This list does NOT necessarily include, gearbox details for the 1968 onwards, Argentinian, Brazilian & Mexican built vehicles (either Bay Window models or Bay Window/Splitscreen hybrid models). Some of these models had factory-fitted VW 1600 Type 1 engines with twin carburettors, for either fuel-ethanol (high-compression ratio of 10:1) or Petrol, 1400cc or 1800cc water-cooled VW engines for either fuel-ethanol or petrol and a water-cooled VW diesel engine.
