Asked this in the brake/wheel section to no avail, sorry to clutter the forum just a bit. Anyway, I have an '89 F-150 2WD RC-LB and a 3" body lift to install. I'm set on 285/70 tires and 17x9 wheels which have an offset of -6. This gonna fit?

Also I'd search if my Droid let me.

 

Bump. Any help is appreciated.

 

I'd strongly consider passing on the body lift. It belongs in the garbage can for so many reasons.

 

Body lift on a 2wd..... Just about f'ing pointless if you ask me. I would rather stake frames than that.

This is my '90 F150 2wd regular cab long bed. 31" x 10.5" x 15" on Creagers




Your tire/wheel combo should be around 32.7" (actually smaller than that) The 31s I have would rub the radius arm at full lock but would clear the rest of the time. I dont recall the back spacing & offset for the rims but they were 15"x8" I know they will rub the radius arms & probably something up front.

 

Body lifts seriously degrade the safety of the vehicle. The bolt used to hold the cab and bed to the frame is longer, and has a lower shear strength than a stock length.

In other words, you stand a great chance of having the cab and or bed shearing off of the frame during an impact accident.

 

Alright I hear y'all on the safety and everything. Thing is I already have the lift, I'm young, and I got money burnin' a hole in my pocket. haha But I realized this morning I oughta rebuild the 180+K motor/quirky transmission and paint it.

Thanks

 

I say continue with the body lift. My '92 2wd has F250 coil springs on the front to level out the front stock 2wd lean. I also have a 3" body lift I am going to install on mine within the next month or so. Putting a 3" body lift on a 2wd that has that stock lean might look pretty bad though.

 

We would level it out (homemade kit ); a lifted truck with a negative rake does look bad. After talking with my Dad he doesn't see the use in rebuilding the motor/trans as of now so paint, exhaust, some kind of lift, wheels and tires, and maybe a gearing swap soonish, perhaps.

Anyway, back to the dilemma, now I just need to know if 4.75" backspace (-6mm) is acceptable?

 

I'd definitely look into re-gearing it. What gears does it have now?

I have 290,000 miles on my original 5.0 and automatic transmission. They have never been opened up and still work great. Just keep fresh fluids and filters in everything, and there is a good chance it will last a long time.

I'd just put some leveling coils or F250 springs from a salvage yard truck or the Moog replacements on it.

 

2.73 or 3.03s according to other posts. I need to call Ford as my door jam plate is missing. And which springs should I consider for a positive rake?

 

Anything more than 4" backspacing is going to rub the trailing arms badly.

 

Does trailing arm=radius arm? I've found that people rub those at full-lock but any other time its fine.

 

I have Moog CC844 coil springs on my 2wd to lift the front end. They are basically equivalent to F250 coil springs. They didn't exactly level out my truck though. Just lifted the front end a couple inches so it looks like it has the rake angle of a 4x4 basically. If I were you, I would definitely get some leveling coil springs from LMC truck or instead, you can get some 2" coil spacers to level it out. I am considering adding some coil spacers to mine, on top of the Moog springs that are already on it, then it should make it dead level, or maybe even slightly higher in the front than in the rear.

 

Alright I'll look into the spacers and all.

Thanks
