The 1998 - 2007 Toyota Land Cruiser 100 Series has a compact torsion bar IFS front suspension, and requires a lot of work to be done in a small space. When lift is added via torsion bar adjustment there is even more spring energy that must be absorbed to adequately control the vehicle. Keeping this in mind, those looking to achieve 0-3" of lift (aftermarket upper control required) can install the Stage 3 shock system for maximum suspension travel and performance with tuning adjustability. ICON engineers have developed a unique 2.5” diameter shock system, with remote reservoirs front and rear, that can handle these demands. 2.5 Aluminum Series reservoir shocks front and rear ensure optimum performance by increasing the duration of consistent damping regardless of situation, keeping the shocks at a cooler operating temperature during extended off-road use. With a lower spherical rod end bearing and heavy-duty upper stem bushings, deflection is kept to a minimum for precise control of the suspension even under high loads. ICON's CDC Valve upgrade is included in this stage front and rear for those desiring an easy way to tune the ride externally with 10 settings from soft to hard.
