Default Leafspring bushings

Hi Guys,

I've spent 4 days searching but couldn't find any solid info where to get the two center pads and the leafspring bolt bushings for my '06 Z51 A6
In the GM part diagrams it looks like you'd need to order a new leafspring, and form what i read the aftermarket lowering bushings are unreliable.

My C6 got he most annoying creaking sound going over bumps especially right front, i already replaced all tie-rods and end-links.
Any input would be most appreciated!

There are many other potential sources of squeaks. Check the big rubber anti-roll bar bushings. They're inexpensive and easy to change. Shock mounts can be squeaky too.

GM has never sold the height adjuster bolts separately from the leaf springs. The bolts you want are the stock reproduction bolts sold by Corvette Central.

I can confirm they are not available unless you buy a new spring. You can get the aftermarket stock repros from Corvette Central, but I doubt they would ever hold up like the OEM ones. I also parrot the recommendation that there is probably something else squeaking.

Thanks for the feedback, i'll check my swaybar bushings and shock top mounts,
I've been looking for shock upper mount bushings but couldn't find them separate, perhaps if i can measure them i can get some polyurethane

They do not sell OEM style/height, only lowering style. As far as I know Corvette Central is the only place to get factory style spring adjusters.
