We've been long in need of a central information source for the weights of key C4 components. So, here it is! If you have weighed anything remotely related to your Vette, please post the info here or send me PM, being as detailed as possible as far as what you weighed, and I'll update this first post as I get those! Also, please include the year of the part and the source of the information, if you did not weight it yourself. If you don't give me a source I'll list you!

BIG thanks go to the C5 Weights, measurements, ratios, strengths, etc thread, which is the inspiration for this one, as well as where I took several of these C4-related C5 weights from. Also, Aardwolf and 95PoloVert have contributed about 2/3 of this list by themselves, so kudos to them!

Without further adieu:

thanks, updated!

shakedown067

Awesome. Nicely done!

Aardwolf

re '88 A/C system (all parts) - 50 lbs, that is all the parts put in a box, even the bolts. A/C compressor, condenser, evaporator, lines, accumulator, bracket, et al.

Also of note the C5 thin spokes are shown at 20 lbs IIRC in the C5 thread but I weighted them several times and keep getting 18 on my bathroom scale. I included the part number in the other weight thread in case weights were compared for a different/same part number. IIRC there were several makers for the wheels and there may be different part numbers with different weights.

18 lbs silver c5 rear thin spoke 18x9.5" #9593799

StealthLT4

Thanks Aardwolf, information updated.

I've contacted TomzWheels and should be getting the weight of all the wheels they carry sometime soon; that should add nicely!

Razor89

The stock Bose AM/FM Cassette head unit, two front speaker/enclosures and the two rear equal 20 lbs from my 89.

Aardwolf

You can take the LBS away from in front of the Braille battery. Just noticed that.

StealthLT4

haha, I just posted it like you gave it ... but fixed now.

I should have a bunch of wheel weights by Monday.

rickneworleansla

I have all the EGR crap sitting in the other room in a box. Don't have a scale though. There's an old thread somewhere that has a lot of this data already. Should be a sticky.

Aardwolf

They are $5 at Walmart! I finally picked one up just to know what all this stuff weights. I was to curious. Five bucks is cheap, bathroom scale.

StealthLT4

I've searched a lot trying to find this stuff, but all I found was "ehh, I think most of my A/C stuff is about 50 lbs..." and stuff like that. I'm really shooting for exact values with this stuff.

95PoloVert

I have a digital shipping scale in my garage, so the items I PM'd you on are pretty accurate.

I have the rear suspension torn down and the tranny out at the moment. When I get a minute, I'll weigh everything up and get the numbers to you.

I agree with Rick...this should be a sticky.

Oh...and that R-D Cross-Frame you sent me weighs 34.40 lbs. without the bolts.

-Scott

StealthLT4

New items added...thanks Scott and Hey8You!!

I picked up a pair of scales there so I could also weigh the (C3) frame (w/C4 suspension) I'm working on. I weigh everything that comes off that car.

rickneworleansla

Didnt see the $5 scale. Do that still sell that one. I just want something cheap to weigh parts. I have no other need for it.

69427

For full disclosure, I bought the $9 scales (rather than the $5 units). I wanted something that looked somewhat accurate but wouldn't hurt my wallet if I accidentally leaked oil all over it and gummed up the works.
