lift set up

[LittleBeast]

October 2004 and June 2006 ARB application guide North American Version both list the specs as follows.

Part #, Free Hight, # Coils, lbf/in spring rate, (application)

OME912, 420 mm, 10.8, 180-300 (medium load Trooper 92-02)
OME913, 390 mm, 9.3, 180-300 (medium Amigo/Rodeo 5door coil spring 98-02)
OME919, 430 mm, 10.8, 200-280 (heavy load Trooper 92-02)

bar diameter is same for each. 913 has lowest coil weight, 912 is + 0.8Kg and 919 is + 0.9Kg.

I verified the application guide is correct as it pertains to the OME912 and OME913 part numbers with a Rep at ARB-USA who cross checked for any updates.
I also cross checked in the Oct 2005 International Application guide and the specs are identical number for number, only the applications are listed as follows;

OME912 (medium load GM Frontera 95-98) and (medium Jackaroo/Monterey 92-2/2001)
OME913 (medium load GM Frontera 99+ 5 door)
OME919 (medium Jackaroo/Monterey 3/2001 - 04, Heavy load Jackaroo/Monterey 92-2/2001)

hope this information is helpful and clears up any confusion about the specs.

As you can see from above the 919s are actually longer by 10mm.

There are tons of threads on these subjects that are helpful.

My question would be while doing ball joint flip should we replace ball joints when they are around $240 for both upper and lower on both sides: http://catalog.autohausaz.com/autoha...t=Ball%20Joint
