Re: 2wd swap

Kids showed some initiative.
He wasn't feeling the 2 link plan.
So triangulated 4 link it is.
And was gifted this 9 inch housing.
Got a 2.91 gear and a 31 spline locker for it.

Re: 2wd swap

Any reason not to do the upper links like this and the lower outside the rail?

Re: 2wd swap

So no more 4 link thoughts?

Anyways back to the front end.
We raised the upper pivot 1" and cycled the suspension 7 inches has -4° of camber change and 3/8 toe at full bump from ride height.

As long as the upper links have enough angle for keeping things centered, where the lowers go is likely decided by project packaging. Keeping the links & springs as far outboard as possible should be a benefit to stability. If there's room outboard of the frame, that's how I would do it.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.

Re: 2wd swap

Tentatively using the stock spring hanger as the lower link pivot.
And boxing the inside of the frame at the hanger for upper link off the diff housing.

Using the OE hangers is how I'd do it as well. Sounds like a solid plan.

The drop of the pocket can make contact when air'd out depending on another variable (wheel diameter) but only when air'd out....

The images also show other details about aftermarket arms that vary.... Where the grease fitting is tapped & bushing barrel OD.

Re: 2wd swap

I believe the lower bag bolt won't be as much of a issue as these grease zerks.

Re: 2wd swap

The grease zerk is a easy fix. Was more worried about catching the bolt on something.

Currently playing 550 cotter pin
pickup..

The 3/8 is faster which can be appreciated up front. I'm slower with 1/4" speed since I use manual control w/paddle valves.
