Big Brake Swap. 98-02 upper arms . 79-94 Cross Shafts. 92-97 ES Bushings.

[87stars_stripes]

Will a set of 98-02 Upper Control arms fit on a box panther riding on 91' cross shafts and a 92-97 ES Bushing (4.3150 )??? I think I know the answer but I am looking for anyone else to verify. Sorry. I know the big brake subject is beat to death but I am doing this for somebody else' peace of mind.


Ford Lists same upper control arm part number for 95-02. (Which for many that know, was a midyear 95 change.)
Ford and Moog list cross shaft kit for 79-94.
Energy Suspension lists control arm bushing kit 4.3150 for 92-97

Believe so, but its the bushings I'm not positive about. I want to say there are two upper control arms in those years, police and non-police. The only real difference is the bushings. I want to say the civi ones use a large/small and the PI use two large. I might be wrong on that, but thats what floats to the surface. But with the proper bushings, the shaft can be put into the later upper arm. The bushings are just dependant on what the upper arm is from exactly.

Exactly the answer I already knew, but I wanted to hear it from someone else. I've heard it from 3 sources now. I put my 00 P71 arms up for sale, and someone didn't believe me that the 79-94 cross shafts are supposed to fit. I didn't want to confuse the post by introducing the Police vs Civi bushing difference, but you are correct that there is SUPPOSED to be a difference in the 95-02 Civi Vs Police bushing. Now I would like to further clarify that I have a set of Civi and Police upper control arms both from 2000 model cars, and I see ABSOLUTELY NO DIFFERENCE in the size of the bushings which is why I previously emphasized SUPPOSED and I have yet to verify why there is supposed to be a difference.

GREAT SOURCE FOR INFO BTW....http://www.idmsvcs.com/2vmod/suspens...ont/index.html

It might be the lower arms that changed. I know something with that bushing kit changed from 79-97 and 98-02. If you get the 95-97 kit, it fits all the old stuff, but theres one bushing that doesn't fit on the late arms.

[87stars_stripes]

Yes. The 92-97 kit 4.3150 fits all 79-97 lowers but it doesn't fit the 98-02 because the lower control arm bushings on a 98-02 have one oval and one round bushing. Still don't know why they list a difference in the 98-02 Police vs Civi Uppers though.

So to be clear, you can use the control arms from say a '01 on a box Vic, you just have to get the right bushings? I have all the parts from a '01, plus the rear disc coming via Fed Ex from an Alabama salvage, so I am curious.

SO I can grab the 4.3150 kit, and get the '01 arms to fit on my '90 vic, and the kit will also fit the lower control arms?

Upper arms did come with a small and large bushing, or two same sized bushings. Cop cars/sports/hpp's and regular cars seem to be the dividing line on that. Which is which I couldn't tell you.

Energy Suspension shows two kits; 4.3150 and 4.3153. 4.3153 is listed as the police kit. So is that the kit with the staggered bushing size or two same sized?

[gadget73]

I want to say its big/small for civilian and big/big for police. If it lists the contents it should tell you. If its got 4 bushings that are the same, then its the big/big set. If you only have sets of 2 bushings that are the same, its the big/small set.

Thanks guys. I was a little lost because all the stickys say grab the 92-94 control arm. But I guess that's only if you don't want to replace the bushings. If you want to replace the bushings, you can use any upper you want.

[gadget73]

The 92-94 upper arm has the cross shafts, but bolts to the later ball joint. If you're doing poly bushings, you do not need to remove the outer shell, so you just burn out the rubber and push in the poly. If you use a later upper arm without the shaft, you will need to press the existing bushings out, press th bushings out of your stock box arms, put the cross shaft into the later arm, re-install the bushings, then burn them out to put in the poly. The 92-94 arms save all that extra work. If you can't find a set though, you takes what you can gets.

[Lazerbeans]

I have police uppers, so they are solid. Looks like they might unscrew, because there's one side that has a hex. Is that the case, or do they still need pressed out?

Or, if I'm thinking correctly, I could forget even trying to get the police bushings out, take a cut off blade to them to get the cross shaft out. Then burn out the late model bushings, install the box cross shafts, and install the right poly bushings. Sound right?

[Lazerbeans]

For that matter will the police shafts even work?
