Axle Clearance Question

Still working on my first attempt at building a frame. Setting up the ride height. Know what I will end up with on the back, the front is the area that I don't know about.

Using a Magnum axle with a Posies reversed eye spring.

HELP

What should the spacing be between the spring clamp plate and the top of the axle (double ended arrow in picture)?

 

three feet?

 

As soon as I figure out how to fit the transfer case and front diff.

 

once you get shocks on there they dont move too much at all...yours looks like plenty of clearance to me...

good luck

take whacha got, add weight, see whatcha get, ask yerself if yer happy. If not change it

 

Looks like plenty.You gotta remember there are not many occasions when an axle will move parallel on both sides,normally oneside up other down as bumps in the road normally only hit one wheel at a time.You need to add 700 lbs or so and see what yopu have then come back and show us.A sbc weighs about 500 lbs or so i'm told plus you need to find out how much you weigh and a p***enger plus trans and fluids all in about 1000 lb.You will also find that although the spring initially gives a little with the weight it gives less with the more weight you load up on it if you get my drift .........................Marq

 

Thanks guys --

Pulled the front end down with a rachet strap until the clamp plate was between 2 1/2 and 3" from the axle, and the shackles at about 45 degrees. With the rear of the frame at the ride heigth that I want the caster is coming in at around 6 1/2 to 7 degrees.

Shouldn't have a problem with bottoming out, have notched the frame over the spring about 3/4" for extra clearance.

Starting to feel better about tacking the diff to the radius rod mounting plates with about a 3 degree angle on the pinion and adjusting the angle of the spring hangers. Using a set of 35 radius rods slightly split with HD adjusters on the ends and will be installing torque bars from the top of the dif to the front of each radius rod, panhard bar and a 41 front spring mounted to a dropped crossmember.

Starting to look like it may be a problem getting a front bumper high enough to meet provincial requirements. http://www.msra.mb.ca/html/mb_regs.html

Will try and figure out a way to get some pictures available once it is rolling.
