from what i have read c6 and c5 front ends are pretty similar...

would the spring fit a C5?

if so anyone know .... the spring rate of a C6 Z06 front spring?

one guy in a different thread said it does fit but.......... i have z51 and the spring rate is almost the same

but hmm, if we could use C6Z springs... I'm interested for sure now

MTPZ06

I assume it would work...but as far as spring rate goes, it was designed to hold up a 7.0L motor as opposed to a 5.7L. Should be stiffer in theory. Interested to know if anyone has tried.

C6Z06 531/782
C6T1 582/850


comprende?

Just because the displacement is larger, does not mean the engine weighs more.......

What are those weights based on?
The LS1 is almost the same motor as an LS6.
Could that be the difference between a clutch/fw/pp combo and a flexplate? Still seems heavy unless one has the harness and ECU piled on top of it too.

Straight out of the GMPP catalog.

Those weights aren't right at all. The LS6 weighs 50 pounds more than an LS1 and an iron block 5.3 weighs less than the LS6 and only 20 pounds more than an LS1? I'm not sure how they obtained those weights, but something isn't right.

Here is some numbers for you:
Since you mentioned Z06 springs, for rate comparison purposes:

C6 Base Springs(lbs) Fr 420/Rr 657, Sways(mm) Fr 25.5/Rr 17.5
C6 Z51 Springs(lbs) Fr 526/Rr 645, Sways(mm) Fr 31.0/Rr 25.6
C6 Z06 Springs(lbs) Fr 531/Rr 782, Sways(mm) Fr 31.0/Rr 27.9

Thanks,Matt

rustyguns

nice numbers! thx

rustyguns

I completely concur..

Ok, since you guys deal in crate motors every day, what are the correct weights?

RichAshley-Black99

So can you use the springs or not

I agree. I'm sure that they weighed them with different options though. Maybe some are/aren't wearing wearing exhaust manifolds, and/or flexplate/clutch assembly? Plus computer, wiring harness.

They should all be pretty much the same weight.

The LS7 might be a little lighter with titanium rods but then you have to add in the dry sump oiling system which I'm sure adds a pretty considerable amount of weight (nevermind the oil itself).

I think the C6 springs do not fit a c5 in front or rear not sure ask in the RR section.

The C6 ZO6 Springs front and rear yes fit on any C5, I just add the 2013 ZO6 Springs and Sway bar to my C5 2003, the improvement is amazing but the car is going to look high, here are the picture of my C5 with the ZO6 suspension.
