Hybrid aluminum parts

[1BADI5]

So I have a '10 PPV that's a DD and being built to be a part time sleeper/racetruck. IN an effort to cut some more weight (was 5300lbs, now 4995 depending on fuel level) I have recently discovered that on the Hybrids there were several body and drivetrain pieces that were made lightweight using aluminum instead of steel. So I'm looking to source some parts, but looking to see if anyone happens to know of have a resource that shows/displays/list the weight difference in these parts.

Now the known: GM said that the hybrid system added 350lbs to the Tahoe, so to compensate for the gained weight they cut it via the mentioned parts below and lighter weight seats.

- Aluminum hood
- Aluminum bumper/crash bar (front)
- Aluminum rear hatch assembly w/fixed glass
- Aluminum driveshaft (4" diameter)

I'm about to pull the trigger on the bumper/crash bar (eBay), Hood (ebay) and driveshaft (eBay)

I guess if no one knows, I can be the test monkey as I have done with several other GM trucks. The driveshaft list it only works with the hybrid (Note: I'm going to take measurements to see if the length is remotely close) should be close between the 2wd platforms unless the Hybrid transmission is really that much longer.


Any and all information would be of value, thanks in advance!

Aero mod it as well you will Drop the coeffent drag down from 0.37 to 0.34

also the hood will only work with the hybrid bumper (slight difference in the cookie cutter) other wise there will be a small gap

Aluminum, suspension parts as well..
Aluminum engine

also get the D pliers and led taillights and rear bumper to go with it..

if you want the measurements from the drive shaft is there any specific spot you would like it measured from?

Do you have the steel lower control arms? If you do, purchase the aluminium ones. Not sure what model years those came out.

he will also have to swap the running broads( if wants to have those) as well..

Yeah I just want the aluminum stuff. The hood should be a direct bolt on

I ordered the hood and front crash bar yesterday. My truck already has the aluminum lower control arms.

I will definitely take you up on the driveshaft measurement. I believe from what I read the Hybrid (2wd) measures in at 61 1/5 (from the center to center on the u joints)
