So we got the 9" fully installed today and made sure everything is tight so I lowered it down off the lift and now I have a huge gap between my tires and the rear fender well. I dont understand why, is the common after a 9" install. The only thing I can think of is I dont have my control arm relocation weld in brackets on. I dont see how that could effect the way the rear sits that much though. The springs are in correct the top sitting in the isolators like there suppose to and the bottom of the coils are exactly the same on left and right. Can my pinion angle affect the rear that much that it makes it sit higher. I eyeballed it on the lift and it looked good. I only was gonna put 15 miles on it to start the break in so it looked ok, thing is now that I think about it there was no load on the rear so I could have been totally wrong when setting it on the other lift where it doesnt put a load on the suspension.

Anyone got any tips for me. I have pro kit springs on and it used to sit pretty low, now with the 9" the rear sits pretty damn high. Thanks for any help or advice.

Yes
The outside diameter of the 9inch axletubes are bigger . You may be able to take the spring isolator out and slide some heater hose on the upper spring coil.

Next thing you will notice is the torque arm bracket will hit the bottom of the floor pan once it starts getting lowered. Mine punched through in a couple of places. So I redid my floor pan to accomodate.

Also the bumpstops will have to be trimmed if you need to go lower or you will be hitting them as you go over bumps.

so then this is common huh? Is there a different spring I can run to lower it some. I dont want to be as low as I was before anyway, I hate rubbing all the time I pull into a parking lot that has a incline or if I have someone else in my car and I take sharp corners. I just want it to come down a bit so I dont like a 4X4, I have a huge rake now and it looks pretty dumb.

Bigger wheels would help but I'd definitely have to lower the car some too. Id have to put 19's back there to take up the huge gap and that would look dumb as hell imo. Or get a whole new set.

Im prob gonna look into doing the heater hose mod.

Also, can control arms effect the ride hight at all, I wouldnt think so but since I dont have the weld on brakcets on I was wondering if that could effect anything?

roy

Control arm will not effect the rife height

haha..mine is going to look like an old gasser then. I have pro-kit springs on the front and stockers in the rear to give it a little rake already. Guess I'll find out when we get the 9" in!

We typically don't see much of a height difference when putting Moser 9 inch rears in these cars. The rear will go up a little, but not normally too much. I'd do the heater hose, which will help. Bob

Im gonna do the heater hose mod for sure when I get some time hopefully this week. Your guess is as good as mine why the rear sits so much higher now. It sits like as high as stock height.

Did the heater hose mod on 12-bolt and 9inch, works great for both of them

Do you have to have heater hose up in there.Everyone I know just takes out the isolator and puts the spring back in.I took my isolator out and it sits about how it used to

No you don't, it does help to you the heater hose if the metal to metal creates an annoying noise. Bob

roy

Cuts down on the noise transmitted into the car, plus keeps metal on metal contact in the upper perch

LOL I was just thinking I put the stones to the LCA's when I reinstalled em and that was the reason it was sitting higher Guess I should take out the isolaters...never heard of this until now

The 28's MT DRAGS should fit fine tho...but it does look a lil 4x4ish with the 17" firehawks on there

drop springs maybe?

well I didnt get a chance to do the heater hose mod today, but I will tomorrow. If I get a good inch out of it I think it will look ok. It has a pretty crazy rake now, lol. I dont want to be as low as I was before anyway so hopefully with a good solid inch it will look better. I'll post up some before and after pics.

So does your rear sound as noisy as my 9" i just put in? Not only gear whine on decel but got a funny other whine as well sounds like I did the KITT mod to it lol.

This kid I knew had a 9" on his LT1 Camaro, it sat real high on the rear and looked mean as hell when he'd pull into a lot meet...

yeah actually I do have a little more whine then I thought Id have. DLS is knowin for having quite rears so dont really know what I think about that. Its still breaking in so who knows. Will adding additive to it quite it down some.

My DLS 9" with a 3.89 has some whine also. My car also sits almost an inch higher than before. I had no idea it would sit that much higher. It is fine though, it rides and handles better with more rear travel.

Be sure to check the pinion angle. A down angle will rotate the spring perch up and make the car sit higher.
