1.The IFS is torn down, and the spindles and stock coilovers are removed. The stock hubs are retained and installed onto the new spindles using the provided hardware (inset).

2.After removing the lower control arms, the drop-down cradle is bolted into the OeM control-arm mounting locations. The cradle lowers mounting position of the control arms and when combined with the taller spindle, keeps the front suspension geometry in a desirable configuration.

3.The stock lower control arms are then installed into the new cradle. The stock alignment cams are installed to aid in re-aligning the suspension after the install is complete.

4.One of the few modifications made to the truck is the enlarging of two holes in the transmission crossmember. These holes are used to secure two strut bars that bolt to the rear of the drop-down cradle and keep it from pivoting under load. Because the Tundra is built with metric fasteners and the lift kit uses standard bolts, the holes had to be drilled up to the next equivalent size.

5.These frame spacers are installed to lower the stock sway bar down far enough to mate back up with the control arms

6.We said this kit bolts on, and it really does. A small 1/4-inch of material did have to be removed from the lower control arm to provide clearance for the body of the new coilover though. A die grinder and cutoff wheel were used here

7.The coilover was bolted in place after the shock-tower bolt holes were enlarged by one drill size.
8.The new spindles bolted...
8.The new spindles bolted right on without modification. Instead of using tie-wraps to secure the brake lines, Pro Comp wisely provided a bolt on bracket to do the job correctly.
