Moog Front End Kit Part Numbers

[mickey]

Tried my new pit-man arm #k7076 Diameter, size of the hole is different, mine would be the taper size hole in pit-man arm the one i got was non-taper,there is also a different size in the thickness around the grease nibble area (could hit headers) order another thinking it was mixed up in packing.

K7041 Idler-man arm is also different, that it didn't come with any washers, which i would need to make up the space in the bracket on the K-Member, and also a thicker grease nibble area.
And neither of these Moog part #  had the rubber grease cups like the originals. 

My car is a 1973 Challenger.

Anyone else notice these problems. thxs

I have a 74 Challenger and I ordered a K7076 pitman arm and the diameter is too big.  It looks like a 1.125 inch diameter while my old pitman arm is a 1.0 inch diameter. Does that mean I have a steering box for a 71-72? I also have power steering. I've seen reference to part number 20144 but I believe that also has a 1.125 in diameter. Can anyone chime in here?? The bend for the K7076 seems to match perfectly but the hole size is about an 1/8 to big.

Ya my guess is that you have the older steering box. ( 1970-72) To the best of my knowledge there are only the two sizes. My cars has the bigger sector shaft box ( 73-up) on it even though it's a 1970 . I'm under the impression the bigger shaft box is a better deal as parts are cheaper for that one . My guess is because they made many more of the bigger shafts boxes than the smaller one.

Good supplier here, ( good info too)

Here's the info for the offset bushings



On my 1974 cuda the stock front bushings are all out towards the fender and the rear is not all the way in. The camber is top in  89.7*( I use a digital level on the center cap or wheel edge). If I rebuilt using offset's in the front only for more adjustment, I would be able to install new stock rear bushings all in, to get the most caster.
      The offset rubber is thin on the outside edge, so they seem good for drag racing's positive caster because it's cheeper than new tube arms.
   On the 68 cuda A body the rear is all in and the front is 1/3 the way in. (89.7* top in.) This car might use offsets on the rear to get more there, and have a round one on each front side.
      I start setting with the bushings front all out and rear all in and measure camber on the wheel and adjust from there. If you can get a small 2" digital level you can set it on the flat side of the spindle (under car) to compare the sides for equal caster (rear tilt).

I'm about to rebuild the suspension on my 73 Barracuda. I've got poly upper control arm bushings but I can't find poly lower control arm bushings. Is there a company that manufactures these?  Also, I have poly bump stops for my upper control arms. I'm contemplating using universal poly bump stops for the lower control arms instead of the factory triangular style. Has anyone tried this?  I have a deep oil pan and I thought this might limit bottoming out.

Prothane has what you seek, their website is terrible, here are their products at Summitt http://www.summitracing.com/search/year/1973/make/plymouth/model/barracuda/brand/prothane-motion-control

Energy Suspension also...these can be ordered through most local parts sellers no freight http://www.summitracing.com/search/year/1973/make/plymouth/model/barracuda/brand/energy-suspension
I used these but don't expect their universal fit dust boots to fit very well and the rear spring eyelet bushings were too big, everything else was spot on.

Thanks, I appreciate the help!

Do our E bodies really need these offset bushings?

Or are they just a personal preference to try to get increased handing?
If so, how much an increase in cornering/handling?

I would think that if you just use new parts all over in the front; you could still set up your alignment good enough for great handling.

I'm sure someone more expert than me will come along, but my understanding is that the switch from bias ply to radial is what makes this a very attractive option.  The stock set up designed for bias plys can't achieve the optimal settings for running radial tires.  The offset bushings allow the suspension to be adjusted to take better advantage of the radial tires.

Since bushings need to be replaced anyhow, I think it is just one of those things that is done because it is so easy to do.

The offset bushings MUST be installed BACWARDS to the instructions to get any good use out of them. REPEAT, arrows must point in the OPPOSITE DIRECTION of the instructions. There is plenty of info about this on the web.

Hi I am rebuilding the whole front end of a 74 barracuda what is the best and most complete kit I can buy and should I do poly and where can I get it I also need a set of leaf springs and a complete wiring harness any info would be great thanks         Is there anybody here that can get me a deal on a complete front end rebuild kit

[Chryco Psycho]

Do as most have done here order all the Moog Hard parts from Rock Auto & a complete bushing kit , if you want rubber Moog / Rock auto is a good option , if you want poly I Use the Energy Kit for about $125 from Jegs , Mancin ior Summit .
 Wiring harnesses can be purchased through Year One or Evans .
Leaf springs I would contact Espo

[chuck]

Has anybody run espo 1 or 2 inch over stock leaf springs and how much did it really raise it any pics any info please

[Katfish]

I got ESPO +1 springs and it was too much.  Hate the going downhill look.
I feel there shouldn't be any space between the top of tire and fender.
Luckily I was replacing the hangers at same time and was able to move to the lower spot.
