wow my steel spool is only 8lbs...those s60s must be huge...just think my aluminum on i had was only 4.5lbs but she went boom

 

AGREED! My New Year's resolution was to strip 200lbs outta my Trans Am, and at least 10lbs off myself! lol

 

Ya its a big *** diff, ring gear is 9.75 inches or somthing like that.

 

Yup, it's a beast.
Strong and heavy, but surprisingly efficient.
Bolts up to all of your existing components except for the driveshaft.

Here's mine as it arrived this summer. Came with a 3" CM driveshaft and Strange racing brakes.

 

took off cruise control and bracket and cables along with tcs and it weighed in at 10 lbs. Pretty close to the listed weight.

 

From what I've seen posted the manual window parts are actually heavier than the power units by a small amount. It wouldn't save any weight but it would be nice to get rid of the finicky power window motors.

 

Wow nice

 

cranks windows heavier than the power windows how can this be. electricl motors are heavy. please explain

 

my B-cool 4 core 1 ton truck radiator was much lighter then the stocker. Costs quite a bit though...

 

anyone have a ansewer to post 131

 

it just is? Ive seen a few guys that checked it out and the power was lighter.

I'm using a good digital shipping/nitrouse scale. gose to like .000 pound or grams even, not some lamo 0-10-20-30 bathroom turd.

Robbie posted up ther other day the hardtop/Ttop roof info. Huge props to him for checking back in and doing all that work.

 

sweet, i have a hardtop with manual windows i am pissed that manual is heavier, guess it beening rare is cool.

 

i would not sweat the "heavier" thing. I don't think it's more than a pound of weight difference between the two combined. If you already have manual windows that's cool, but I thought you were looking to swap power windows for manual. It is definitely not worth it to swap one for the other.

 

^^ on no i like my crank windows, ppl and there bad window motors haha

 

My 2000 Trans Am passenger seat (leather) is 40 lb. as opposed to the 37 listed.

 

Thanks! Now I can finally throw away the firebird hatch that's been in the bed of my truck for a couple months. I picked it up for free just so I could weigh it, and haven't had the time to go to my friends shop to borrow his scale. It has too many cracks and chips to justify fixing so it's going in the dumpster.
I'm assuming that your weights are with the glass removed?

 

I decided to weigh the firebird/formula hatch myself before chunking it. Since the glass alone is supposed to be 30lbs, the 28.5 sounded a tad off to me. Hatch with no glass is 50lbs-3ozs.

 

I didn't see a spool listed...how much ligher is that than a regular differential? What about gun drilled axles?
