Lifting a vehicle does cause the center of gravity to rise and rollover may become easier, always avoid situations where a rollover may occur and always wear seat belts. Larger tires will cause braking performance to decrease. Mixing of brands and lift components is not recommended. 1. Park vehicle on level ground and take before measurements to use for reference when adjusting the height on the new keys. LF___ RF___ LR___ RR___ 2. Block the rear wheels and jack up the front of the vehicle and support with jack stands on the frame so the front wheels are off the ground. 3. Remove the front tire and wheel assemblies using 22mm socket. 4. Measure the torsion key adjuster bolts for reference points for later reinstallation. Left Side____ Right Side____ (Figure1) Figure1 Figure2 5. Remove the adjuster bolts from the torsion key keeper using 21mm socket and save for later reinstallation. (Figure 2) 6.

Figure3 Figure4 7. Remove the keys from the torsion bars. Sometimes the keys rust weld to the bar the use of an air hammer and striking the back of the bar thru an access hole in the back of the torsion bar cross member. This usually breaks the bars free from the keys. 8. Install new keys onto the bars in the same location as the old ones were located on the bar. 9. Now that the suspension is unloaded the shock extenders will need to be installed. 10. Remove the lower shock bolt and nut using 21mm socket and 21mm wrench and save for reinstallation. Push the shock up out of the way and install shock extender. Use stock bolt to mount the extender to the control arm shock mount. (Figures 5 & 6)
