? about trailing arms
Why are the trailing arms kicked up in the rear?

Re: ? about trailing arms
To make them parallel to the ground? Is this one of those "Why did the Chicken cross the road" type questions..

Re: ? about trailing arms
No chicken question. When I was making my trailing arms for my 56, (which are straight), someone told me that if they were not angled up I would have vibration in my drive line. My arms at ride hight are level to the ground. I didn't think it mattered, but before I finish everything up I thought I'd ask.

Re: ? about trailing arms
You need to correctly set your rearend pinion angle to keep all the vibration in check.

Re: ? about trailing arms
I agree with the pinion angle issue,but why not make them a straight arm and clock the saddles to compensate?

Re: ? about trailing arms
Its for the spring mounts. The springs need to be 90* to the frame otherwise you get a real goofy ride. You can mount the axle on an incline plain just turn the nose down to the correct angle and use coil overs behind the axle.

Re: ? about trailing arms
you're right.Looking at a bad angle pic of that area of my truck I didn't think the spring sat on the kicked up area,but after looking closer it does

Re: ? about trailing arms
I won't set my pinion angle till my motor and trans is in, and sitting at ride hight. Then weld my saddles in place.
