Southbound 0 Posted November 19, Posted November 19, Specifically: Are the same shocks installed on Z85 and Z71 trucks? Do Z71 trucks sit higher?

Are the spacer blocks the same thickness on both trucks? Do the Z71 jounce bumpers affect anything about how the truck rides or sits? Could I still do the drop shackles and remove the spacer blocks on a 2WD Z71 truck without problems? Am I going to get too close to the jounce bumpers?

The Z71 has off-road jounce bumpers, which are elasticated cushioning components that stiffen the suspension. Jounce bumpers have an unusual design and include a mounting plate and one or two tubular extensions which stick out from the mounting plate, so they are easy to spot. They look like stacked donuts. Measure the wheel diameters and tire sizes.

The Z71 has larger wheels with a greater diameter and thicker tires. Lift the hood and look inside the engine compartment for a flat, metal plate designed to keep out rocks and debris as the vehicle moves across rugged terrain. The protective plate will be located underneath the engine, between it and the undercarriage. You may also get onto your knees and look under the vehicle for the skid plate. It is a flat, metal plate which lies directly below the undercarriage and is affixed to it with metal bolts at either corner.

If either protective plate is present, the vehicle is a Z Z85 cars do not have such protective plates because they are not four-wheel drive, off-road-style vehicles. Measure the fender flare widths using your measuring tape. Start from the inside edge and measure to the outside edge of the curved flare. Fender flares are usually black plastic curved arches which add additional coverage to the existing wheel arch over each of the tires.

The Z71 has wider fender flares than the Z85, adding up to 2. Standard Z85 flares measure 17 inches, so the Z71 would have at least Fender flares are also known as wheel arch extensions, as explained by Jungle Fender Flares. Slide under the car and look for torsion bars beneath the engine. They are large, heavy pieces of metal stretching the width of the chassis. They serve as supports for the whole undercarriage, so are very easy to spot because they stand out.
