Are 3.55s worth it?

[unclejim]

I am interested in installing 3.55 gears on my '92 Viper. Is the performance difference noticable enough to warrant the price. I hate having 6th gear sit idle...

Interested in hearing from anyone that changed their ratios and pros/cons.

Yes it's worth the $1K price. I had them on muy 94 and really enjoyed the extra SOTP feel the gears provided. It actually made 6th gear useable on the freeways. IMO it was a great upgrade to do and didn't affect my car in any negative way. I bought the gears through Jon B and had Unitrax (Anaheim,CA) install them. Good luck.

Oh yeah they are worth it No more downshifting to 5th in slow traffic, you can just keep that puppy in 6th and keep on truckin

Your better off with the 3.33.Your 1/4 mile won't suffer.Maybe 1 or 2(modded) guys have run 11 sec 1/4's with 3.55,it's just too hard to launch.Been there!

I don't think that it's any more difficult to launch that the 3.07s, and you always feel that you are on the meat of the torque curve, with a large improvement in 6th.

You do shift a bit more in town, and I got a couple MPG less driving around, and you have to really baby the car in the differential gears break-in period, but I'd do it again in a heartbeat.

Even though you don't a single HP, the improvement in the feel of the car's power is tangable.

Some people who later add lots of power (as in a supercharger) will switch back to a 3.07 stock gear set, because with 600HP+ it does become hard to get traction in lower gears, and for drag racers you have to shift to 5th gear to get through the 1/4 mile.

If you are unable to use 6th now, the 3.55 will fix that.
I did it for that reason. It's better in slow traffic too.
Feels faster off the line but you will probably need to get new tires to get a little extra traction. I got the Kuhmo 700 stickys. Use Unitrax gears.
Do it, you'll like it.

I had 3.73s in my '94, and they were a blast around town. I can get you an entire 3.55 differential delivered to your door for $1495.00 let me know.
