Three Things We Did To Improve Our 1995 Chevy Suburban’s IFS After A Torsion Bar Lift
Our goal was to better our Suburban’s ride quality, suspension travel, and CV shaft angles.
One of the most inexpensive and quickest ways to lift torsion bar-style IFS is by increasing the preload on the torsion bars, commonly referred to as "cranking the torsion bars." There can be downfalls to this method. Harsh ride quality, limited suspension travel, and increased CV shaft angles can be some or all of the primary results. It is possible however to avoid these things following a torsion bar lift. How is this accomplished? Well, there are complete kits available from aftermarket suspension companies that address these issues. However, we set out to address these issues by using the a la carte method for our 1995 Chevy Suburban that came to us with a torsion bar lift completed by a previous owner.
Our Suburban Had Bad Ride Quality Among Other Things
When we purchased this 1995 Chevy Suburban, plans of a solid axle swap were right at the top of the list but quickly dropped off as other aspects of the vehicle were modified or repaired, and other project vehicles entered the picture. Plus, this vehicle serves as a road trip machine that's used to traverse mild, scenic trail systems, and it's not a dedicated trail rig. This being said, the previous owner cranking the torsion bars created a domino effect, and among other things, the ride quality both on and off road was less than desirable, to say the least. It was time to remedy that.
We set out to improve three major functions of the IFS on this Suburban: 1) Increase the suspension travel through installation of aftermarket upper control arms 2) improve shock damping by installing quality monotube shocks and 3) correct the CV shaft angle by lowering the differential through installation of a differential drop kit. While the truck will always have a stiffer ride due to preload on the torsion bars, addressing these three areas will dramatically increase ride quality and suspension performance while still utilizing the existing aftermarket torsion bar keys and factory torsion bars. With the exception of having to fabricate a couple of differential drop brackets (more on that in a minute), installation of the components was fairly straightforward. We're pleased to report that after the mods, the Suburban suspension handles much better and the overall ride quality has been dramatically improved. Here are the highlights of what we did:
