If you want to get really into it, Tenneco actually owns Monroe.



United States

• Virginia Beach, Virginia - A JIT manufacturing facility that makes exhaust systems for the Ford F-150 plant in Norfolk, Virginia
• Cozad, Nebraska - Products: shock absorbers; plant is scheduled to close at the end of the year
• Hartwell, Georgia - Products: shock absorbers
• Paragould, Arkansas- Products: shock absorbers; struts

Indiana

• Elkhart - Manufacturing plant that primarily makes exhaust components for other Tenneco facilities using stamping, hydroforming, and CNC bending processes. In addition, Elkhart fabricates some frame components for Harley Davidson on CNC benders. The Elkhart plant is the only manufacturing plant that is owned (rather than leased) by Tenneco.
• Ligonier - Manufacturing facility that makes full exhaust systems and related components for Ford Motor Company, Chrysler, and Honda. Ligonier is one of the plants that has its own tubemill which takes steel on coils, gradually rolls it into a pipe and then welds the seam shut. This newly-formed pipe is then cut to length and used on the various lines within the plant. Some of the cut pipe is also shipped as-is to other Tenneco plants.
• Angola - Products: Heavy duty products, spring eye bushings, fluid bushings, torque rod assemblies, links, & V-rods.

Michigan

• Marshall - Manufacturing facility that makes full exhaust systems and related components for Ford Motor Company, Chrysler, and General Motors. Marshall is one of the plants that has its own tubemill which takes steel on coils, gradually rolls it into a pipe and then welds the seam shut. This newly-formed pipe is then cut to length and used on the various lines within the plant. Some of the cut pipe is also shipped as-is to other Tenneco plants. The Marshall facility is also equipped with multiple high speed automatic muffler assembly lines.
• Monroe - Houses the North American business unit which consists of almost 500 employees involved in multiple disciplines such as design, product engineering, sales, and marketing.

^^^^^^^^

Hey, those IN towns are all near me!

 

Cool thanks for the info.----------jcwclm heres your pwned lol.

 

Ok.....................

 

 

You would have to get sensatracs that are longer than the stock cherokee size if youre going to lift. I think some of the older yjs and scramblers are longer than the cherokee but have the same mounting hardware. Usually they give you the sizes extended and compressed

 

Diesel, Thanks for the great info on the OME. I've been wanting a set of those for a while, but was having a hard time justifying the $85 per shock. It's nice to know they are just a Monroe Magnum with an OME sticker on them.

I don't suppose you would know a part number for 2" lifted shock would you? I'm having trouble finding them online, and I'm running 2" OME HD leaf springs.

Also, where can you find them for $33?

Thanks for your help.

 

hehe i slit steel for Tenneco...lol

 

Normal Monroe Magnums for the XJ will work with 2" lift, anything over 3.5" I wouldnt do.

And some places online have them for <$40

 

I just spoke with the phone rep at Monroe, I asked if the Monroe Magnums would ride smoother than the too stiff Reflex I have now. The guy told me no, the only softer riding Monroes would be SensaTracs. Diesel, do you agree?

 

Completely, its very hard to manufacture a gas shock that rides as well as a hydro shock. You cant incorporate PSD into a gas shock either.

 

Thank you sir! Very much appreciate you helping us understand shocks.

 

From Monroe:
"Both the Monroe Sensatrac and the Monroe Reflex are a similiar design, a twin-tube low pressure unit. The Sensatrac is Monroe's older design, the Reflex uses more modern technology to do the same thing as a Sensatrac.

Monroe's New Reflex shocks and struts for cars and trucks. Featuring their new Impact Sensor, which acts like a switch between firm and soft compression damping. Under normal road conditions, Reflex shocks deliver better handling than O.E shocks. The Reflex design also has a soft, light valving for average daily use and driving. "

Here is what confuses me, My reflex shocks are Always very stiff, like the "Impact Sensor" does not work. The shocks on my cherokee were installed by the PO and lord knows how old they are. I guess it would be reasonable to assume the "Impact Sensor" stops working over time. Or the wrong shocks were installed by the PO. Is there a model # stamped on the Reflex shocks? Are they valved differently for different vehicles?

I do wish there was a good factual comparison of shock stiffness/ride quality and longevity. If someone knows of such a thing please show me.
