Photo 2/23 | ReadyLift 4 Inch Suspension System 001 | Our ’15 Chevy came to us just as stock as can be, with the agreement to lift it to a comfortable level. These third-gen Silverados make for a great platform for customizing, and you can do just about anything to them. This is just another example of how the aftermarket followed the 1500’s development with these easy-to-install kits.
Photo 3/23 | ReadyLift 4 Inch Suspension System 002 | This SST lift and level kit from ReadyLift was simple enough,
including 4-inch strut extensions, rear shock extension brackets, 3-inch rear blocks with new U-bolts, new upper arms with pre-pressed ball joints, greaseable bushings, and all new hardware.
Photo 4/23 | ReadyLift 4 Inch Suspension System 003 | Since the truck owner was a local, we enlisted the help of the Tech Center shop manager, Jason Scudellari, and used our home shop to do the work. We raised the truck up, got to work unbolting the tie rod, and removed it from its location in the spindle.
Photo 5/23 | ReadyLift 4 Inch Suspension System 004 | Next, we unbolted the sway bar endlink from the lower control arm. After the swaybar was free, we rotated it up and out of the way. No need to fully remove the sway bar, as our lift does not require it to be relocated.
Photo 6/23 | ReadyLift 4 Inch Suspension System 005 | Since we were lowering the upper control arm and strut, we had to unclip the ABS electrical connector for reinstallation later.
Photo 7/23 | ReadyLift 4 Inch Suspension System 006 | The brake line had a bracket that we also removed as we were swapping the upper arm with the one in the kit. The new arm would serve as the new mounting point for both the brake line bracket and the brake line.
Photo 8/23 | ReadyLift 4 Inch Suspension System 007 | To prepare for the new strut spacer, we removed the harness clips from the top of the strut studs, as well as loosening and removing the strut nuts. Before that, we supported the lower arm and the spindle assembly with a jack to make it possible to lower the strut.
Photo 9/23 | ReadyLift 4 Inch Suspension System 008 | Next, we loosened and removed the upper ball joint nut, to prepare to remove and replace the upper arm. We used the jack to lower the lower arm and spindle out of the way, making sure not to overstretch the brake line.
Photo 10/23 | ReadyLift 4 Inch Suspension System 009 | We loosened and removed the upper cam bolts, saving them from the scrap pile for reuse when the new upper arm is installed. It was now time to remove the upper arm from its original location.
Photo 11/23 | ReadyLift 4 Inch Suspension System 010 | When placed side by side, the new arms are stronger, have a greaseable ball joint with Zerk fitting, and just plain look better. The old arms were destined for the scrap heap.
Photo 12/23 | ReadyLift 4 Inch Suspension System 011 | Our new arms from ReadyLift feature polyurethane bushings, and these crush sleeves designed to hold the washers while the arms are installed. Our sleeves and bushing were greased up from the supplied lubricant, and we were ready to install them on the new arm. We had to install the strut spacer first, so we left them on the floor for now.
Photo 13/23 | ReadyLift 4 Inch Suspension System 012 | With the strut dropped down far enough, but still supported by our jack, we had enough room to install the strut spacer. We slipped it over the stock bolts and tightened down the lower nuts, before installing it back into the stock location and tightening it all down.
Photo 14/23 | ReadyLift 4 Inch Suspension System 013 | The new ReadyLift arm was set to be installed. The crush sleeves did their job and held the washers in place as we muscled the new arms into place in the factory location. We bolted them down, but just loosely for now and tighten them up later.
Photo 15/23 | ReadyLift 4 Inch Suspension System 014 | We were now ready to start the reassembly process of the front suspension. We reconnected the new upper control arm with its new ball joint to the spindle, and torqued the ball joint nut down to 85lb-ft.
Photo 16/23 | ReadyLift 4 Inch Suspension System 015 | The tie rod end was next to be reinstalled on the spindle and was torqued down to 65lb-ft. The swaybar was rotated down and installed using the factory hardware into its stock location. With that, our front suspension was that much closer to being completed.
Photo 17/23 | ReadyLift 4 Inch Suspension System 016 | All that was left was to install the brake line bracket to the new control arm with an M6 nut from the kit torqued to 5lb-ft. We also reconnected the ABS, and torqued the arms to 120 ft-lbs.
Photo 18/23 | ReadyLift 4 Inch Suspension System 017 | With the front suspension all buttoned up, we moved to the rear. First, we rigged both sides of our rear end with a custom-made adapter for a transmission jack to support the rear end.
Photo 19/23 | ReadyLift 4 Inch Suspension System 018 | We unbolted the upper and lower bolts of the rear shocks ready to add the rear shock extension. With the addition of lift blocks in the rear, we had to drop the shock’s mounting point.
Photo 20/23 | ReadyLift 4 Inch Suspension System 019 | Here is a close up of the shock extensions, which is a simple and economical solution to the desire to add a few inches to the rear shocks.
Photo 21/23 | ReadyLift 4 Inch Suspension System 020 | Underneath the rear leaf pack, we’d planned to add a lift block from the kit, so we had to unbolt the U-bolt plates and the U-bolts from the axle.
Photo 22/23 | ReadyLift 4 Inch Suspension System 021 | Here, we are installing the kit’s new U-bolts and the lift block. All we had to do was drop the rear axle down far enough, using our custom rear axle support rig that is attached to a handy transmission jack. With blocks in place, we bolted back the whole assembly, tightened down all the hardware, and our lift was done!
Photo 23/23 | ReadyLift 4 Inch Suspension System 022 | All that was needed now was to mount up our new set of 18x9 Raceline 930 Shift wheels with 285/65R18 Falken Wilpeak AT3W tires. Our ’16 Silverado 1500 was ready to mod the mean streets of SoCal and do it in style! With just a little lift and proper wheel and tire package, out not-stock-anymore truck has gained a little bit of attitude and great looks in just a few hours.
