Performance Accessories Premium Lift System for Chevy and GMC Trucks

Jul. 24, 2012 By Dan Sanchez

Adding a set of 33- or 35-inch tall tires to your Chevy/GMC pickup is essential for any off-road enthusiast. But the fact is that not everyone can afford the cost of a full-suspension system. So for those who want to raise their trucks to run a set of cool 20-inch wheels mounted on mud-terrain-style tires, thereís a new, less expensive alternative to gain as much as 5-6 inches of lift without major suspension modifications.

The Premium Lift System from Performance Accessories comes with nylon-reinforced body blocks, bumper brackets, hardware and Gap Guards. Everything you need to install this system yourself in 6-8 hours.

Combining a two-inch leveling kit with a three-inch body lift was the idea behind Performance Accessoriesí Premium Lift Systems. These kits range in price from as low as $220 to $800, depending on the vehicle make and model. This makes them a great alternative for those looking for raise their vehicles on a tight budget. Furthermore, the kits are designed to retain the factory ride and suspension geometry, so the truck maintains its comfort on the road while getting the extra ground clearance when driving in the dirt.

The leveling portion requires removal of the factory coil/spring unit from the body. Youíll have to remove the top mount bolts, bottom shock bolts, tie-rod, spindle bolt and sway bar end links.

The Premium Lift System for 2007-í11 model 1500 series GM pickups, PN-PLS109, retails for less than $725 and allows the vehicle to run 33-inch-diameter wheels and tires. So why didnít anyone think of this before? The reason is that most leveling kits and body lifts werenít designed to work with each other. According to Chris Faustmann, R&D manager at Performance Accessories, the leveling portion of the kit is designed to split the front-end lift by using both a coil spring spacer and a strut assembly spacer. Faustmann says this eliminates excessive spring load and allows the coil spring to operate within its normal motion and retain the stock ride. It also limits the overall length of the strut assembly so that the ball joint angles remain within stock settings when the suspension is under full compression and droop.

To ensure the coil spring goes back correctly on the spring perch, Faustian marks them so that itís easy to line up after the assembly has been removed to install the spacers.

The body-lift portion of the kit raises the vehicleís body in relationship to the frame, so thereís a direct increase in ride height when using larger diameter tires. The body-lift mounts fit on top of the factory body mounts and are made from nylon-reinforced body blocks. The kit also comes with powder-coated steel bumper brackets, high-grade hardware, a CNC machined steering extension and urethane Gap Guards. While the kit sounds simple enough to install, be forewarned, there are many parts to the complete kit, and it does take some time to do it properly. Faustmann recommends to set aside a full day (6-8 hours) to do the job.

For safety reasons, itís very important to use a proper spring compression tool. If you donít have access to one, consider taking the coil/shock assembly to a services shop that can do it for you.

Because the installation involves lifting the area around each body mount to install the Performance Accessories body blocks and hardware, weíd recommend getting access to a hydraulic lift. It makes the job much easier than doing the work on your back with a floor jack and jack stands.

The kit comes with two spacers for each side. One fits on the top of the spring mount over the factory studs.

Both methods work fine, however, and once youíve gone around all of the truckís body mounts and added the new blocks, the height of the body will leave a gap between it and the factory bumpers. Therefore, youíll have to remove the factory bumpers, front grille and any bumper panels to install new steel bumper brackets. The instructions in the kit illustrate areas that may need trimming in order to add the brackets that raise the mounting point of the front and rear bumpers. Once this is done, however, everything goes back together nicely. In addition, the space between the body and frame that is visible within the truckís wheel wells, are hidden with the urethane Gap Guards. These serve to extend the length of the factory wheel wells and protect the engine from moisture, mud and dirt. 

Because the bumpers will have to be removed for the body lift, itís necessary to remove the radiator core cover, front grille assembly and bumper covers.

Installation of the top strut spacers and coil spring spacers requires that the strut assembly be removed from the vehicle. The coil spring must also be compressed to remove the factory urethane spacer. Therefore, make sure to use a proper spring compressor tool or have a professional shop do this part of the installation for you. The top strut spacer simply fits over the studs of the strut assembly and the reassembled coil spring unit is bolted back into position in the truck.

Before the vehicle is raised, the steering shaft coupling must be unbolted. Weíll be adding a CNC extension here later.

With the installation completed, the added lift will easily fit a set of 33-inch-tall tires to give your truck the custom appearance youíve been craving. Furthermore, since thereís no change to the truckís factory suspension, the ride is still smooth, stable and the modifications wonít void the factory warranty. 

Faustman unbolted the factory body mounts and went along side each one, lifting it with a jack high enough to add the new body block and new heavy-duty hardware.

With three inches of increased body height, the CNC machined steering extension is installed, connecting the steering shaft back together.

Up front, these brackets raise the bumper mounting points to properly position the front bumper to the body.

An extension bracket for the parking brake is also included for proper operation with the added body height.

The new rear bumper brackets are positioned into place to mark the holes that will attach it to the bumper cross member.

The cross member assembly is unbolted and removed from the frame. A cutting wheel is used to slice through the weld and remove and isolate the cross member.

Two new holes for the bumper brackets are drilled following the directions in the instructions.

With some minor trimming, you can see how the new cross member and bumper supports fit behind the rear bumper.

The bumper is then put back into position and is bolted onto the frame.

A support brace between the bumper and hitch ensures a solid mount that wonít wobble or move while towing a heavy load.

The final steps in the installation are to install the front and rear Gap Guards. These are held in position and holes are drilled for the retaining push-in pins.
