FS: 1993 Caprice axle with custom 2.14 ratio and aluminum drums—for max MPG

For sale is a rear axle from a 1993 Chevy Caprice sedan, with the 7.625” 10-bolt differential and 28-spline axles.  It has been custom fitted with a rare 2.14:1 ratio gearset, and rare 1980’s GM 9.5” aluminum brake drums (weighing approximately 7 pounds each).   The center bore and bolt holes on the drums were custom machined to fit the 5x5” Caprice hubs and studs.  The ring and pinion were professionally installed, using new bearings and seals.  The axle assembly came from a car with 98,000 miles, and about 6,000 miles have been put on the axle since the conversion.  The axle shafts and bearings were not replaced, but are in good condition.  The parking brake cables were replaced at the time of the conversion, and a brand-new brake hose will be included as well.  In other words, the entire assembly comes ready to plug and play.

This axle assembly should fit any B or D body sedan made since 1977.  It will also fit B-body station wagons—the 6,000 miles I logged were in a 1994 Caprice station wagon.

The 7.5” 2.14 ratio gearset is the highest (numerically lowest) that GM ever made, and is the ticket to the best possible highway mileage in these cars with an automatic transmission (or manual transmission, if you don’t use engine-off coasting).  I was able to achieve 35 MPG on the highway using this axle in my station wagon, with no engine-off coasting.

I’m selling because I’ve discovered that with the use of engine-off coasting, gear ratio is not as important for maximum economy.  However, EOC is not possible with an automatic, so if you don’t want to convert your B/D body vehicle to stick shift…this setup will reduce weight and get your RPMs down, yielding the best possible highway mileage.

Asking $500.  I’m located in the greater Roanoke VA area, and I’d be willing to travel a reasonable distance to meet for the sale.  I’d prefer not to ship, but I’ll consider it if you make arrangements.  I do have a pallet I can strap it to, but I’ve never shipped anything this big before.

So far, there hasn't been much interest in this rear end. Would anyone like to make an offer?

If it doesn't sell soon, I'm going to take it apart and sell the parts separately. I'm guessing those aluminum drums would be the perfect setup for someone with an Impala SS who drag races--minimal weight AND minimal drag...

Interesting setup. Never thought a hyper miler would want a wagon

Most everyone hates the 2.56 let alone anything higher. Probably have more luck selling the brakes to a sedan owner than anything else.

Have you seen my build thread? No other vehicle that seats 8 and can do serious towing has as much potential as a B-body wagon--up to 46 MPG in my case. For "regular" driving, my other car is a Geo Metro that consistently averages 85 MPG in the summer.

Yep--and selling the 2.14:1 ring and pinion to a land speed racer. Seriously.

Do you still have the drums? What would you want if you do?

The drums are still available. I'm away from home right now, and will be through the weekend, but I'll get back to you about them early next week.

Last chance--if no one wants this rear end, I'm going to take it apart and sell the parts separately (for real this time!).

Make me an offer if interested!
