Can anyone tell me what made up the Z51 package in 2004 ?
(part numbers would be great, too)

THANKS

 

The RPO Z51 Performance Handling Package was made up of the RPO FE3 Sport Suspension and a power steering cooler. The FE3 Sport Suspension part of the package included stiffer stabilizer (sway) bars, springs and heavier shocks. I don't have all the part numbers, but here's the one's I do have. You may want to check with your local dealer to verify that these are the most current numbers.

Springs:

Spring, Frt Y (FE3, FE4) GM # 22178729

NOTE: The FE3 and FE4 (Z06) suspensions share the same front spring.

Spring, Rr Y07-67 (MM30, FE3) GM # 22146646
Spring, Rr Y07-67 (MM6, FE3) GM # 22179020

NOTE The FE3 Rear spring is different for C5's dependent on whether the car is equipped with the A4 (MM30) or MM6 6-speed transmission.

Stabilizer (Sway) Bars:

Shaft, Frt Stabilizer Y07-67 (FE3) GM # 10424741
Shaft, Rr Stabilizer Y (FE3, FE4) GM # 10424743

NOTE: The FE3 and FE4 (Z06) suspensions also share the same rear stabilizer bar.

Sorry, but I don't have part numbers for all the other Z51 parts such as for the power steering cooler, its plumbing and related parts, the shocks, the sway bar bushings and clamps, end links, etc. (In model year 2002, GM went to aluminum end links on all C5's. To my knowledge, the aluminum end links on you 2004 CE coupe regardless of factory suspension would be the same as those used on the Z51 in 2004. But again, you should verify this with your local dealer.)

I agree the stealership should know all parts required for this conversion. They may be expensive though! Be Careful!

 

Thanks for the info
Here's to you
