i recently put Moog 5390 springs in my car. the summit racing site says these are the correct springs for my car but its riding way to high in the front. i have a 350 without air conditioning and have replaced the intake with an edelbrock RPM. any suggestions? are lowering springs the way to go? i also replaced all the bushings and put in a front disc conversion kit, is there any chance something is binding there?

Can you measure the height from ground to rocker on both sides as per the assembly manual? Can you post a photo? What tires are you running?
Assuming you installed everything according the service manual; did you torque everything with car weight on the suspension?

Are you sure the upper end of the springs are properly seated in the spring pockets? This is a blind installation and it's very easy for the upper end of the springs to get hung up on the centering feature in the spring pocket. When that happens the car will sit about an inch or more higher. Also, did you loosen the control arm bolts during the installation? If so, did you have the weight of the car on the springs when you torqued them?

thanks guys for your responses, that's probably where we went wrong, tightened everything up and then put the springs in. Going to re-do that part this weekend and will let you know.

Did you replace the rear springs also?

yeah shocks and springs but i had a shop throw those in when i brought it in for the alignment.

update - this past weekend we re-torqued the upper and lower control arms with the weight on the suspension. it seemed to bring the front end down enough. I'm happy with how it looks.

the rear end seems to be a bit low though. maybe some adjustable coil spring spacers there would bring it up. i say adjustable because one side is lower than the other. comments?
