### What is the best differential gear ratio?

The higher the ratio, the more revolutions per minute. Towing: For pickup trucks released after 2010, the best axle ratio for towing falls somewhere between 3.55 and 3.73. This range provides good acceleration for V8 gas and diesel engines.

**What gear ratio does a c5 Corvette have?**

The standard gear ratio is 2.73 and the performance option is 3.15.

**What gears are in a C5?**

The stock C5 coupe and vert comes with either 2.73 or 3.15. Check the decal in the glove box. You can also check by looking at the rear differential; it’ll have a tag on it. An A4 coupe or vert comes with 2.73 or optional 3.15 gears.

## Did a 1967 Corvette have Positraction?

While horsepower ratings might have been purposefully understated at the time, all big-block Corvettes came with a Positraction axle, firmer suspension, and four-speed manual transmission.

### What differential does the C5 Corvette have?

Corvette Rear Differential Exchange – 3.73 / 3.90 / 4.11 : 1997-2004 C5 & Z06. Give your C5 or Z06 Corvette unbelievable acceleration with our exclusive 3.73, 3.90 and 4.11 Differentials. If your C5 currently has a 3.15 gear, you can expect almost a full second improvement in 1/4 mile ET’s.

**What are 3.31 gears good for?**

The 3.31 might be capable of towing the trailer. But if you are towing the majority of the time, you probably want the 3.55 because it will tow better and provide better fuel economy loaded.

**What does L 88 mean on a Corvette?**

For the uninitiated, the L88 designation means the car packs a 7.0-liter V-8 (hence the “427” on the hood), 4-speed manual transmission, and a Positraction rear differential. The engine was officially rated at 430 hp but made much more in reality.

## Does C5 Corvette have limited slip differential?

While late-model Corvettes of the C5 and C6 varieties certainly have improved factory-standard limited slip differentials compared to earlier generations, no owner can be too careful about setting their car up with the proper diff for the use (and abuse) their car is most likely to get.

### What rear end is in a 1984 Corvette?

Both generations came in either a Dana 36 or Dana 44. –1984-96 Automatic transmission Corvettes have Dana 36 rear ends.

**Can you tow with 3.31 gears?**

**How does the differential affect handling on a corvette?**

To understand how the differential affects handling, we need to review how the Corvette Positrac differential works. As you know, both the Eaton 65-79 and the Dana 80-82 Corvette differentials use springs to preload the clutch pack that transfers torque to the unloaded tire.

## What is the gear ratio of a non-posi-traction corvette?

If the driveshaft yoke rotates a bit past four turns during one full wheel rotation, you would have a 4.11 rear gear ratio. Divide the driveshaft rotations into one [4.11 / 1]. Non posi-traction Corvettes use the same formula, counting two revolutions of the wheel while using one as the divisor. What do the numbers mean?

### What should the rear axle ratio be on a 1956 Corvette?

If you’re drag racing, the rear axle ratio should be 3.90 or higher. Everyday cruiser rear axle gear ratios tend to be less aggressive, in the 3.50 or lower range. Time to do the calculations! NOTE: A very few 1956 Corvettes used Positration Rear Axles stamped “3.70.11 HT” or “4.56.1HT” indicating gear ratio and Hi-Tork.

**Would an overdrive transmission change benefit my Corvette?**

This is the prime example of how an overdrive transmission change would benefit: 1969 Corvette with an original Muncie M20 that has a 2.52 first gear ratio with a 3.36 rear axle gear ratio. Our combined first gear ratio would be [3.36 x 2.52 = 8.46], not too bad for a 427 cubic inch engine with plenty of low rpm torque.
