ARB Bumper weight?

[saburai]

Quick Q.
Anyone know what a ARB for a Cherokee weighs?

Many thanks...

I don't know the exact weight but from having thrown mine around I'd guess a little under 100 lbs without the winch in it. Let's say 90.

If you are wondering about whether your springs can handle it... you may need to add a short spacer to balance it out.

Its about 80lbs without the winch for the Kj.

ARB was 80ish lbs. Didn't make it squat down until I put the winch on it. IIRC the winch was about 80-90lbs. All said and done it was less than 1/2 inch.

Shipping weight is 150# so I would think that the Bumper weighs in 100 to 110lbs.

Next question:

Do you have an idea on the weights of some of the other winch bumpers out there? i.e. AJ's, C4X4, Nate's, etc., etc.

Thanks

Ok, I'll bite.

Why do you want to know this?

Well, for one I like to make educated decisions about my vehicle modifications.
I'm concerned - in no order with things like fuel mileage, over hang, polar rotational movement, strength vs. weight, etc, etc.

When I put an ARB on a buddy's XJ, I could very easily move it around. I highly doubt it would affect the lift height on the front.

EDIT: I just talked to a friend who works at the head US office not too far from my house. He was thinking about 120 lbs before a winch.

Fair enough.

The reality is that adding a bunch of weight on the front end will have its affects. The front springs will be compressed a touch, more weight, etc.

No matter which combination of parts you settle on they will all be within say 100 lbs of each other. Likely less. That means it will be a mostly negligible difference between each configuration.

FWIW, I'm the type that resets the odometer every time I fill up and I always squeeze 50-100 kms out of the Jeep after the fuel gauge warning light goes off. Fairly consistent. Adding the ARB was worth a loss of 1-2 mpg (US gal) depending on the type of driving that was done. My normal commute is cruising at ~90 km/h for 30 minutes, ~120 km/h for 10 minutes, urban traffic for 5 minutes. Aerodynamics being what it is, the 120 km/h stint is probably what is taking most of the fuel economy.

Polar moment of rotation and braking? Sure, you notice it a little when you jump between two XJs where one has the bumper and the other does not. But, it is not as marked a change as I notice when I jump back and forth between the S2000 and the Civic Si for example. The XJ has a big lump of a tractor engine in it that weighs more than a Chevy small block (for example). And it is a long engine. The engine still remains the over riding component (and transmission and transfer case) that determines the feel as far as quick direction changes are concerned.

Overhang, that is indeed one place where the ARB suffers. That said, you have to determine what your intended usage of your Jeep will be. My best friend bought my stock black XJ from me this past fall. He's been doing the mental gymnastics of which bumper and winch combo to go with as he builds the rest of the Jeep. I think he is going to end up with the ARB. He's realistic about how the Jeep will be used and he likes the look. Neither of us are rock crawlers so how it works in that environment is secondary (tertiary?).
