What the difference between a z71 and a z92?

"Z71" is a Regular Production Option, or RPO, code that U.S. automaker General Motors uses for its off-road suspension package. This particular option is most famously associated with vehicles out of GM's Chevrolet division. The "Z92" on the other hand is an off-road package that is offered by American Luxury Coach.

Z71 is a package that is available solely on the LT and LTZ trims, and it delivers features that make the truck fully proficient in handling off-road situations with ease.

The Z71 package also comes with distinctive visual features and badging, including a Z71 graphic on the instrument cluster and a special finish on the interior trim pieces. A Z71 badge is found on the grille, marking the truck as a fully-capable off-road machine.

Z71 Off-Road and Suspension Enhancements

The major feature of the Z71 package is its enhancements for a vehicle's off-road capabilities, including bigger wheels -- specifically, 18-inch aluminum wheels -- which are fitted with on- or off-road blackwall tires. The Z71 offers specially tuned springs and mono-tube shocks for the suspension to better support the vehicle's weight and tire contact, as well as further dampen shock. This is combined with an automatic locking rear differential to improve the distribution of drive shaft power.

Z71 Exterior Enhancements

As for exterior features, the Z71 package accentuates the wheels with wheel flares integrated into the vehicle's body above them, and replaces the steel grille with a chrome one. The exterior additions are not just cosmetic, though, as the tubular assist steps enhance elevation into the vehicle, the recovery hooks are for towing purposes, and the skid plate and front fascia protect the vehicle's undercarriage and nose, respectively.

When it comes to finding which trucks offers the most capable and best off-road package, an excerpt of an Tfltruck.com article shares the following advice:

Every pickup manufacturer in the United States offers at least one off-road oriented trim package. In general, the recipe is the same, but the amount of the off-road “spice” varies from brand to brand and from truck to truck.

The recipe is to tune the suspension (springs and shocks) to suit a variety of off-road surfaces. Generally, this makes the suspension is a little softer and more compliant, which also helps on pavement. In many cases, ground clearance is increased. Next, throw in some special software. This includes a hill descent control or a terrain management systems that adjusts how the 4×4 or 4-wheel-drive auto system appropriates power. Next, add some under-body cladding to protect some or most vital components. Finally, mount some off-road biased tires.

Different manufacturers apply various amounts of the aforementioned ingredients to their trucks. Let’s leave the Chevy Colorado ZR2, Ford Raptor, and the Power Wagon out of this comparison, as they are specialized off-road trucks.

What packages are we talking about?

How about the Chevrolet Z71 and Trail Boss packages? Ford has the FX4. GMC has the All Terrain and All Terrain X. Nissan has the PRO-4X. Ram offers the 1500 Rebel and the 4×4 Off-Road packages. Finally, Toyota is there with the TRD Off-Road and TRD Pro trucks.

In its most simple role, your suspension needs to hold your truck up and keep your tires planted on the ground. There are several ways to get that done but each has strengths and weaknesses.

You cannot compare factory suspension designs without talking a little about caster and camber. Caster angle is built into the front suspension so the steering is more stable and will return to center. Camber is the angle of the tire to the road – negative camber is when the tire leans in at the top and in contrast, positive camber is when the tire to leans out at the top.
