Handed springs - question

I just installed some Rovers North springs (genuine "style" ride and height). After installing them, and after reading some threads on this forum, it now appears to me that they are handed. The backs are even in height, but front passenger is 1/2 higher and front driver a full inch higher. I don't like the way the truck is sitting now (unevenly).

The question is have for you folks is how to fix this.

I see a bunch of threads about adding spacers to raise up the shorter springs - but I don't want the truck raised any higher.

Are there any methods for lowering the front/longer springs?

Thoughts?

How long ago did you install them? If you have the longer side on the driver (and battery) side I would let them settle for a bit and then reevaluate.

Don - 1 week. Entire front is higher but yes highest on driver /battery side. Can it really drop an inch with time and settling?

Are you saying the front is higher than the back?

The springs compress at a set rate, so many pounds per inch of compression. If you sit in the drivers seat, the springs on that side will compress a predicted amount. If you weigh 225# and your front spring rate is 225# per inch, when you get in, the springs will go down a total of one inch, depending whether you have a SWB or LWB it may be a half inch at the front drivers side and a little less at the rear drivers side (because the rear is usually a bit higher spring rate).

Is your fuel tank full or empty when you are measuring? Is the truck completely assembled, or partly taken apart because you're doing other work? Tool box in the back? Left or right side? Got an extra battery in there somewhere? There are all kinds of variables.

On a recent drive we were commenting on the lean of a friends Lightweight as he drove down the road. It was really noticeable! Then someone jumped in the passenger seat to experience an "old school" ride. Like magic it rode level the rest of the trip, as long as the passenger was there.

Yes front is riding much higher than back. Gas tank is pretty much empty. Sucks - My part time OCD is annoyed by this one.

aftermarket rovers north "oem style" springs (same height and stiffness). I'll have to check the colors when I'm home but these are them below. These are the 4 that RN told me to get:

Yes - what springs are you running where? I thought the fronts usually end up a little lower especially if you have HD bumper and winch.

Agree - full tank vs empty, tool boxes, batteries, etc can change stance. Curious - how are you measuring or just an eyeball figure?

Can you tell us what part numbers you installed? Stock 90 front springs should not be longer than stock rear springs. they should be almost the same length and both should be handed.

http://www.red90.ca/rovers/springinfo.html

Are you certain you have the springs in the correct locations?

I can assure you we wouldn't send you to AB! Possibly you didn't get them from us? I'm not sure what springs you got, but it should be the following:

Front Left: NRC9446 - blue/green
Front Right: NRC9447 - blue/yellow
Rear Left: NRC9448 - red/blue
Rear Right: NRC9449 - white / yellow

No worries

I just pointed it out because last time when Ben Little ordered springs they were aftermarket and not identical to the Genuine units.

Okay. First, let's make sure that you have the correct color codes on the correct corners.

Assuming there is not a lot of non stock weight in the truck, it should sit properly.

Did you ask for genuine springs or aftermarket. Unloaded, they should be about the same height (front and rear). The rears should have a heavier bar used in the springs.

Looks like my installed spring colors are as follows:

Front driver: blue and green
Front pass: blue and yellow
Rear driver: red
Rear pass: yellow

Is this correct?

Unfortunately, you are going to have to pull and measure them. Most likely return them for proper ones.

Zack, I'm assuming all this info is for the D90 and not the D110?

The HD110 rear springs I ordered from RN are the same part number. I have a definite lean. Are the rears supposed to be handed too?

You can't do either. They have closed and ground ends. They need to be properly heat treated or they will bend permanently the first time they compress.

Can you measure the height of the springs while parked on a flat, level surface. That would help determine where you are at and what would be a good way to go.

Why did you change springs in the first place?
