What is a good gear Ratio for me?

[89IROC&RS]

well, im away from my literature right now, so ill back down on this one

i do know the 10 bolt for third and fourth gen cars are interchangeable, at least on the inside. the Borg Warner rear on the other hand is a 7.75in ring gear, and i thought was used in the 5.7L IROCs. maybe im wrong on this one, im not exactly in a great frame of mind right now, yall will have to be patient with me.

[ridge_runner]

the inside isnt... the diff on the 3rd gens are 26 spline the 4th gens are 28

[ridge_runner]

well 86 and prior is diff. i believe.. or 87 i 4got when they converted to 28

are they also called "detroit lockers" and I also hear that they make alot of noise when turning true??? and does anyone have them on there car???

Mid way through the year in 88 they converted to 28 spline. However after 88 You actually would still find some but not many 26 spline axles used on rear drum brake equiped cars

I have a Auburn Pro Locker which isn't exactly like the Detroit locker but same idea. and yes under hard turns with heavy throttle it makes a ratcheting sound but under coasting conditions you can barely hear it

"ratcheting sound" I thought it would be a cool sound like a flowmaster or blow off valve

[FormulaLT1]

No the Auburn series unit uses clutch packs to lock the axles in place so you get a ratcheting sound other units might make another sound though. Some use bearing's so I'm not sure what they sound like

so you guys telling me that 3:73's are a happy medium?

[FormulaLT1]

Yes 3.73's are a good all around gear for a Auto and If you have a stick you can even go upto 4.10's without causing any major problems

[ridge_runner]

yea go with the 3:73s

[89IROC&RS]

personally, if its a highway car, i dont recomend more than 3.42 or 3.45, depending on your rear, 10 bolt vs 9 bolt. if its gonna be a weekend play thing, then 3.73;s are fun, drag car, 4.10's

would that go for all gen camaros????

now what's the deal with 2 and 3 series carriers? can someone explain that in simple words.

[FormulaLT1]

2 series units are for use with 2.73 -3.08 gears and have a thinner seat and place the gears farther away from the pinion because the pinion gear is wider. 3 series units are 3.23 and up place the ring gear closer to the pinion gear. Richmond and Strange make gears with 3.23 and higher ratio's that will work with 2 series units though
