Icon Vehicle Dynamics Land Cruiser 100 Series Stage 3 Shock Install
Off-road project builds are never easy, and sometimes it’s not until you get into the build do you fully understand what you want – or better yet, what you need. That is the case with this 1999 100 Series Toyota Land Cruiser, as the time had finally come to step up the shock performance of the LC.
This 100 Series is a daily driver and a consistent weekend trail rig. Quite a few upgrades have already been made to the suspension components, such as Old Man Emu suspension, Total Chaos upper control arms (UCA), Sway-A-Way torsion bars and Slee Off-Road heavy rear springs (upgraded from OME 863 medium springs after the addition of the rear bumper).
Now it was time to make the jump up to a high-performance shock setup, so we looked to Icon Vehicle Dynamics and its Stage 3 Performance Shock System for the 100 Series. The Stage 3 shock system consists of front and rear 2.5-inch diameter shock bodies, both of which feature remote reservoirs for additional shock damping and the ability to maintain fade-free performance under intense off-road use. The shocks can help provide up to 3 inches of lift, though the use of a uniball aftermarket UCA is required for the front shocks. The shocks are constructed with a lower spherical rod end bearing and feature a heavy-duty upper stem bushing for added durability.
The shocks are tuned specifically to the 100 Series platform, but the key difference on the Stage 3 shocks is the addition of Icon’s CDCV (or CDC Valve), which provides a simple way to adjust the shock from soft to firm in 10 different settings depending upon the terrain or intended use. The CDCV is controlled via an externally mounted dial on each of the shocks, so adjusting the firmness is as simple as twisting the CNC knob. No cutting or welding is required for the shocks, and the only additional step beyond securing the shocks in place is mounting the remote reservoir in the wheel wells.
Since the Icon shocks are direct replacement parts and require no drilling for installation, other than for the reservoir mount, the installation is something the competent garage mechanic can tackle in the garage or driveway with the proper tools, jack and jack stands, in roughly half a day. These installations are something your local off-road shop does all day as well, so if you want the professional to tackle the job it shouldn’t take them more than a few hours.
Once the shocks were on the rig, the change in the feel of the Land Cruiser was immediate. In spite of all of the upgrades, added weight from the front and rear bumpers, sliders, and larger spare tire, with the Icon Stage 3 Performance Shocks the vehicle handles everything around town so smoothly it reminds us of how plush the ride was when it was in stock form. Getting out of town and onto the trail is where the Stage 3 Icon shocks truly shine. Every little bump or rock is far smoother in comparison to the OME nitrogen shocks. One of the biggest benefits, however, is the additional travel of the Icon shocks. In many instances the rear differential lock wasn’t needed to gain traction on a challenging climb, because the extended travel of the shocks helped keep two wheels on the ground in most situations, even during extreme articulation.
The CDCV valve is also makes tuning the shocks extremely simple. When loading up with gear for a day in the desert, the Land Cruiser was weight down so much the suspension felt just a little soft, but all it took was a quick stop to adjust the knobs for additional stiffness and the ride quality improved immediately. The simplicity of the CDCV system makes the move up to the Stage 3 system very worthwhile, and one of the best features of the shocks is they are fully rebuildable as well.
The Stage 3 Performance Shock System from Icon Vehicle Dynamics is a high-quality upgrade for this 100 Series rig, but Icon’s suspension kits aren’t only available for Toyotas, as they offer kits for just about about truck and SUV on the market. At $2,600, the Stage 3 System isn’t exactly cheap, but the quality and performance benefits are definitely worth the extra coin.
