The passenger side of my car sits a good 3/4"-1" lower than my driver side for some reason. No fat chicks in my car, and its not just the rear, its the front as well. It might be dumb to think so but are the springs interchangeable? like a rear spring on the front and viceversa? was wondering if the people that put the lowering springs on might have put both rear springs on the passenger side and both front brings on the driver side? i'm just looking for answers cause its bad enough to make my car pull to the right even with perfect alignment. its the only thing left that it could be. any ideas? let me know. thanks.

Please don't put a rear spring in the front, lol

Usually, factory sets the passenger side lower than the driver's side in order to level the car out when the driver sits in the car. I think the springs are probably switchable from left to right, but NOT front to back.

As far as pulling, are you sure it's not your brakes?

it's nothing new. switching springs side to side won't help.

it seems far fetched to think that the factory design would have the driver side higher because the drivers weight would even it out. how would they guess if the driver was going to be 100lbs or 400lbs? I have never bought into the idea that the factory intentionally sets the drivers side higher for that reason. I think that is a myth that has been repeated enough that people now spurt it out as a "fact".

Hello
Like everyone else mentioned....its a common situation with these vehicles. I am under the impression why they are lower on the passenger side is because the drive-line is off set to that side (reason for the hump on the pass floor pan). If you have any other questions feel free to ask and I will be more than glad to help. If you have any other questions feel free to ask!
Thanks

I thought the hump was for the older cats and the floor design was never changed when the cats changed.

+1. LT1 cat used to sit under that hump. never re-designed the floor-pan for the LS1s

I've seen corner weights on stock cars and there's really very little weight difference side to side. I think it was something like 50lbs more on the passenger side which would easily be accounted for by driver's weight, yet it is still tilted. who knowsss.

supposedly the spring perches in the rear are uneven but i've never measured

Any idea on how to even it out?

Hello
Like I mentioned before its common on these vehicles and it is even worse on a lowered vehicle. A adjustable coil over would work great to allow you to adjust the ride height. If you have any other questions leave me know!
Thanks

my car was even side-to-side, but after changing springs the front passenger side is almost 3/4" higher then the driver side.

I have had luck rotating the rear springs on the perches to get the rear to even out.

The F-Body lean is a by-product of a PHR equipped car. The purpose of a PHR is to centrally locate the rear in the chassis but there are variances in chassis dimensions from car-to-car. Combine these variances with a fixed length PHR and you get varied ride heights and mis-matched side-to-side heights. If this does not make sense to you then consider the following: Remove the PHR completely and you will see that the car will level out. This is because everything shifts to it's natural resting spot on the springs. This is where the suspension "wants to be". Unfortunately, this position is rarely center. Installing an adjustable PHR will properly center the rear however you also get a jacking effect as the PHR pulls the body over, rocking the springs on their seats. This is just the nature of a PHR. Watts links do not have this issue.

Winston Cup guys use PHR's too and compensate by adjusting individual spring heights after every PHR adjustment.

Up front check the sway-bar end links to see if they're loose, bent, damaged, and if the Left and right links are adjusted the same. If that doesn't solve your problem then remove the front sway-bar and lay it on a flat surface to make sure it's not bent.
The rear will normally sit lower on the passenger side with the factory 10 bolt rear, since the passenger side lower spring seat sits at a slight (but very noticeable) angle towards the rear of the car. The drivers side is different and the lower spring seat is level.

I always thought that hump was because the way the tranny for the v6's sit. hmmm. learn something new everyday.

This is the most intelligable answer I've read thus far throughout all the many threads on this subject.
I'd like to add to it in that the variances should not be in my opinion large or more that an inch or so..I think once u go past an inch things are very likely pointing to other problems in addition to this mentioned.

Thank you BMR Sales and u just earned yourself a customer...if u have the double adjustable version.

I had the car inspected also....by a frame and alignment shop...they gave back a printout and aligned it with no problems...report came back with no front end problems. Car was bought on the spot. Thanks again.
About an inch in the back and almost a 1/4 variance in the front. I'll level this out somehow.

Glad to be of help and yes, we have double adjustable PHR's in stock, ready to ship when you are ready!
