Suspension RPO

[Chris]

My friends 2006 Silverado crew 2wd with a 4.8 and 3.23 gears has z85 suspension. Did the Z85 give torsion bars to 2wd instead of coils? Curious I have the base z83 suspension on my 2wd and it has coils.

That is interesting cause I have the coil-overs as well.

Did a little digging, but it looks to be a HD suspension/Towing type package for better control and minimize the bouncing while towing.

Doesn't mention the t-bars though. I know 2wd 05-07c SS's, 04-05 VHO's, and 06-07c VMax's got them.

Little more lol, http://www.fullsizechevy.com/forum/archive/index.php/t-464502.html Your friend should also have a Z60 code for High Performance Suspension Package.

Cant have both z60 and z85. I told him to send me a pic of his rpo tag. I havent looked it in in about 3 years

Well, http://www.marshu.com/images-website/car/gm-firebird-camaro-rpo-car-door-manufacturer-codes/gm-firebird-camaro-GM-RPO-car-codes.pdf

 

This biggest damn list of RPO codes, can't find the Z60 but the Z85 does state" Z85 : CHASSIS PACKAGE, HIGH PAYLOAD FIRM RIDE " the Z83 is smooth ride but from what I have read, it's only firmer shocks.

My friend is a dumbass. I thought he had coils. Well he did. He is a vehicle mechanic in the air force and doesnt know what his truck has
