corvette c3 beefing up the rear end.

genochevy1 · #1 (**permalink**) 02-16-2005, 01:42 AM

Does anyone have any good Ideas on how to beef up a 75 corvette rear end to handle 900 hp?

I would like to just add supports to cure this problem, but I don't think I'll be able to fix it that easily, I'm open for ideas?

I don't want to, but I feel I'm forced to put a 9 inch rear end in it but I don't know were to start. Do any of you know of a web site that has step by step instructions on how to do it for a c3 vett?

Thanks Geno

Replace it, the stock rear will not hold up to that much power for very long.

Take a look over here for strong C3 rears.

Would a Viper rear do you any good? They hold quite a bit
of torque and they're IRS.

After market axles and axle-retention device mandatory on any car running 10.99 (*6.99) or quicker and any car with locked differential. Cars running 10.99 (*6.99) or quicker that weigh more than 2,000 pounds (907 kg) with independent rear suspension must have swing axle differential replaced with conventional differential housing assembly.

With 900 HP you will not be allowed on any track with stock rearend. I can't see you driving on the street with it either.

Best info I could find requires a 4 link set up with shortened Ford 9" housing. I would contact Art Morrison.

I have been checking out the web sites and thanks for the Info. I still have not found a step by step (pictured instructions) on how and where to make cuts. I found how to guides on the newer models like C5's but not on the C3's. I'm still open for ideas, keep them coming!

Thanks Geno
