These are rare gears that can push to 200+ mph on highway type landspeed top speeds.
Ring and pinion gear ratio, meaning lets say if you have a 3.00 to 1 gear. Means the Pinion will spin 3. times to 1 wheel rotation.
The size of rear Tires also effect the ratio too, but not going there to make it simple for those learning how it goes.

Ring and Pinion in Posi Carrier 12Bolt
Posi Carrier unit, has spring set. How to tell if you have a Positraction unit? Jack the rear off the ground(Chuck block the front wheels first safety) then turn a wheel. If both wheels turn same direction, its in there.
Dont take a chance breaking something doing a burnout to see if you got 1 or 2 tire marks

There was also a 2.29 ratio that Chevy put in a 12 bolt 396 2 barrel.
ReplyDeletethe Difference between the 2.28
8 7/8 that came in Caddys and the 2.29 that came in a 12 bolt are the spline pitch 45 vs 60 for the 12 bolt
Ive heard about a 2.29 12bolt car gear, but not sure if it really exists. 2.73 and 2.56 a 16×41 tooth only ive seen and bought for 12bolt car
DeleteFound it 2.29 its 17 - 39 tooth
DeleteThere is also a 12 bolt 2.29 ratio that is very rare looked for years never found one. It 12 bolts have 60 deg. splines while the Caddy 10-12 8 7/8 have 45 deg splines
ReplyDeleteAlso there is a 2.26 Ford 8.5 gears that can be made to work in 8.8 housings fairly easily.
The Caddy 2.28 gears are fairly common
ReplyDeleteI was the first NA Lakester over 300 in 2008 at B'ville. I was powered by a BBC using a GM 7.5 2.14 gearset with a Torsen unit out of a Firebird
Awesome hearing about the achievements. I know the salt flats are dangerous and getting on it is a risk but I feel as all do - it is worth it.
ReplyDeleteI just got a GM 12 Bolt 2.29 ring and pinion just now but not sure have to test if it fits Chevy 12 Bolt rear
