Kvan rear leaf springs

    All Pathfinder K-van 4wd van conversions used the stock rear springs, with spacer blocks added.

Why are you considering replacing the rear springs? Bad ride? Sagging? Squirrley handling?

Here are some things to consider

    Many van owners choose to have the rear springs re-arched when they become weak and sag. It lasts for awhile, but eventually they will sag back to their original dilapidated state and then some, because you are heating and reshaping tired fatigued spring steel.

    Look where each individual leaf rides against the leaf above it. If the pads are gone, the lower leaves can wear into the upper leaves creating a pocket that the lower leaf gets tapped in when the spring wants to articulate past the wear pocket. This action has a loud snap related to it.

    Check the spring eyes and bushings, the spring bolt may have worn through them, which can drop the van an inch or so. Also check the center of each leaf between the u-bolts. You may see a leaf or two with a crack in line with the spring center bolt. If you decide to replace a cracked leaf, do the identical leaf on the opposite leaf spring or you may come out lop sided.

The following spec’s are from an old Dayton catalog and shows the many spring choices offered on GM vans of multiple years.
