Is anyone out there running leaf cars either mono or multi? I am looking for some pics to see how to position the mounts on an underslung chassis. Does anyone run a multi and mono?? Please provide some input.
thanks.

If you go to landrums site they show the proper angles the leafs are supposed to be installed in.

you want them as far out as possible on the rearend also.

are you planning to use rear sliders or shackles?

Ive got a trick in my mind rear set up on my new car because I have to use shackles, I made the top shackle mount that is usually in the frame on my nova, slide forward and back, thats my weight jack...

I can send you a picture of it if wanted.

Hey dirtrace: Sounds like a good idea. I would like a picture of the set up as we run 2 leaf cars on the west coast.
thanks, orange2mod

Thanks for the responses. I am setting it up with rear sliders. I am interested though in your shackle idea.

Orange2Mod - would you sure some photos of the rear leaf setup. I am struggling with packaging everything on the axle.

please email photos to reckow.d@duraauto.com
thanks

orange mod, ss4

sent you pics.

If allowed I would stick with the sliders myself, I have allways used the nylon block type and never ever had a issue.

Here I have to use stock shackles.

I have heard with sliders you have to clean them every week. Did you do that or did you not have any problems with them getting dirty?

ss4: I don't have a scanner so I can't send any pics. If you look in a Coleman book or probably any of the others the plate that is drilled out for the U bolts has a shock mount on it. They also have one for a mono leaf that has mounts for a coil elim. and a shock. Hope this helps, AL

I ran the nylon block sliders and never looked at them in a pavement car, I dont see how any dirt whatsoever could possibly effect them. the nylon slides on a round piece of tubing, what could go wrong??

just dont overtighten the bolt, snug is enough.

I would never use the brg type, because obviously a brg could fall apart.

I really don't like the rear slider boxes. The stop us from doing some things with the leafs. They must be centered at ride height. If you change your arch you must have a way to change the rear slider box to center it at ride height.

If you can make them adjustable you might be okay, but I think you are just making everything more complicated. How much easier can it be than rear shackles?


Also it is hard to fit the leaf suspension on an undertail chassis. There isn't much clearance under the rear end unless you inset the lower rails.

shackle angle also has to be correct so either way the upper mount needs to be mobile to work properly.

how far inset? on the right side it is 12 3/4 inches in from the outer rail.

so what is the advantage of sliders???

Does any body have a thought on the AFCO roller bushing? Good or bad?

Keep it sideways!

You just have to inset it for clearance. We don't run undertail on the leaf so you will have to figure it out yourself.

The problem we had with the box sliders was that if you took a very light hit back there, you had the possibility of binding. We had this to happen several times. YOu would bounce the car sitting in the pits and it seemed alright only to have it get on the track and bind up. We finally ended up selling that car and getting an FR-1 from Racemart that used shackles. It worked better, but was still prone to bind if hit in the rear. WE finally went to a half leaf with coil springs on top of the rear and a J-bar. Works GREAT!!

If you measure the chassis frame height and get it back to the same place with the new spring it will be very close to the same as before the change.
