Upgrading a Fairly Stock Suspension

I would start with a rebuild. All bushings, ball joints tie rods... Etc.

At the same time as the rebuild I would got to a 1" torsion bar.

Then I would go and do the rear springs and associated bushings.

Don't forget the proper alignment.

Then frame connectors.

Then the sway bars.

I would also do a firm feel stage three box along the way depending on the money situation.
