Sorry if this shows up as a double thread. I couldn't figure out how to delete the old thread.

I have a 2000 Expedition Eddie Bauer 4WD with converted air-to-standard suspension. The front coil-overs that came with the conversion kit are Monroe Sensa-Trac 58518's. The problem is that these coil-overs raised the front 2" over stock, while the rear is at stock height.

My question is do I have to use coil-overs, or can I use standard shocks? The Monroe 58518 coil-overs are 19" uncompressed and 12" compressed. I need to find something 2" shorter. I just want to get it back to stock. I'm not interested in lifting it.

If coil-overs are required, then does anyone know of any adjustable coil-overs that actually lower (the Ranchos only lift)?


Thanks!

Mike

 

If you have them then you have to use them. Coil overs support the weight of your vehicle where as normal shocks just dampen the ride. As for other brands look at fox, king, foa, sway away, bilstein, and a lot of other brands make them. All you need to know is your new desired compressed and extended length and your spring rate.

 

Thanks for the info. The reason I wasn't sure about the coil-overs is because the stock setup (granted it was the air suspension) used non-coiled air shocks. So, I wasn't sure if just regular shocks would work.

I'll see what I can find with those brands. I've been to a couple of their sites, but haven't found a way to search by length and spring rate.

Thanks!

 

You may be able to work it by finding the right spring to fit your current set-up. All you need is a spring change to lower the vehicle. Contact some of these companies and see if they have one that will fit and tell them what you're trying to accomplish.

 

Think I may have found it. I looked up applications for the Monroe 58518 and found that they are OEM replacements for the rear shocks on a 73 F100 pickup. So I checked to see what they used for the front on that truck. The Monroe 58253 are used up front. They are identical to the 58518s in specs & mounting, but 2" shorter! Well, 2" uncompressed, 1.5" compressed. But I think that will do what I need. Thanks for the responses guys!

 

Don't get sucked into compressed and uncompressed numbers...they mean nothing without the spring rate and tell you very little how it will workout once on the vehicle. Normally, the shorter spring will have the higher rate and will not settle as much under the weight of the vehicle.

 

Without the compressed and uncompressed numbers though, he could end up with a shock way too long or too short, but that's why I said he need's to know his spring rate too. He could go with a smaller coilover same spring rate which should lower it a little, or just a softer spring which will let it settle more but at the same time may provide a more bouncy ride.

 

Ahhh yes, he was talking shocks instead of springs...my bad!
