Nitto Terra Grappler G2 Jeep Grand Cherokee Review
How to Properly Add a 44-Foot Camper (And Air Springs) To Our Ford Super Duty's Workload: A Truck for Work And Play, Part 3
Low
We've spent the last two years throwing everything simply the kitchen sink at the set of F load range Nitto Terra Grappler G2 all terrains mounted under our 'eighteen F-250. It has towed mini excavators, skid steers, a dump trailer full of dirt, rock and sand, and a host of recreational vehicles. At present, information technology's time to come across how the Super Duty's heavy-duty tread holds up with a 44-human foot fifth-wheel toy hauler in tow. Only as we embark on this new chapter, we're making sure the truck itself is up to the task of towing at its max GCWR. Nosotros're equipping information technology with a LoadLifter 7500 XL air spring system from AirLift.
For years, air springs (or air helper springs) have been a popular way to improve a truck's towing functioning by eliminating squat and promoting level towing, restoring steering stability, maximizing carrying capacity and reducing body roll and trailer sway. Of course, information technology's difficult to ignore the proper headlight aim and improved ride benefits that too come up with adding air springs. In addition to installing the LoadLifter 7500 Forty arrangement, we're throwing AirLift's Wireless Air EZ Mount system on the truck. With wireless control over the air springs, they can be custom-tailored precisely where we desire them, no matter which trailer we're hooked to.
Why We Need Air Springs
While we've lugged the dump trailer around at 16,000 pounds no problem, the overhang of the master bedroom on this recent acquisition proved a flake likewise much heft hovering over the bed of the Super Duty. The fifth-bicycle Cherokee Wolf Pack toy hauler measures 44 feet in length, boasts two bedrooms (one existence the aforementioned primary), 2 bathrooms, slide-outs, a sizable garage, a kitchen/dinette area and a living room. Loaded up for a big weekend, it tips the scales at more than 16,000 pounds.
AirLift LoadLifter 7500 Twoscore Organisation
Offering vii,500 pounds of load leveling capacity, AirLift'due south LoadLifter 7500 XL air spring system comes with everything needed to install it on a '17 and newer Super Duty. This includes the massive air springs, mounting brackets, frame braces, fittings, Nylon air lines and all necessary hardware. True to its advertising, the LoadLifter 7500 XL organization was a 100-percentage bolt-on install, with the simply drilling required having to practise with the install of the split, Wireless Air EZ Mount system (more on that in a fleck).
Massive Air Springs
The centerpieces of AirLift's LoadLifter 7500 Twoscore system are its girthy air springs. Each spring measures 7-inches in bore (vs. 6-inch diameter on the company'south LoadLifter 5000 series air springs). The larger diameter provides for superior load leveling at lower pressures and the commercial-grade, dual convolute bellows offer 20-percentage more air volume than the springs found in its LoadLifter 5000 systems. The air jump's terminate caps are fabricated from a loftier-forcefulness, nylon composite that AirLift claims makes them corrosion-proof. The AirLift LoadLifter 7500 XL springs' maximum recommended pressure is 100 psi.
A Commodities-In Thing With Very Few Hang-Ups
Post-obit AirLift's extensive, highly-detailed instruction booklet, we had the 7500 XL system installed in about six hours. Our i snag occurred on the commuter side air leap assembly, which needed to be partially disassembled in order to finagle it into place between the truck's drooping rear beam and the frame. Conveniently, AirLift includes three different air spring assembly lower leg adapters to match the three rear axles available on '17-newer Super Duty'due south. Our F-250 required the adapters that fit the 10.v-inch Sterling's 3.5-inch diameter axle tubes. Note: the Dana M275 measures 4.0-inches and the M300 axle'south tubes measure a beefy four.5-inches.
Wireless Air EZ Mount System
AirLift's Wireless Air EZ Mount arrangement arrived mostly assembled and we were pleasantly surprised that the tightly packaged system located both the compressor and manifold on one shared mounting bracket. Nosotros singled out the inside of the driver side frame rail (rearward of the transfer example) equally the best spot to mountain the compressor. To clear the factory fuel lines mounted on the frame rail, we sourced our ain stainless steel spacers. So came the process of stringing the supplied air lines dorsum to the air springs.
Fuel Door Manual Fill
Should the air compressor fail for any reason, we have a slick fashion of inflating the air springs the one-time-fashioned style: behind the fuel door. The holes for the Schrader valves were made using a stepped bit on a right-bending drill, carefully enlarging the holes as we went until the correct bore was accomplished (roughly 5/16-inches). Annotation that with two Schrader valves we tin inflate each air bound individually (i.e. dual path command).
Wireless Communication With The Compressor
Once the Wireless Air EZ Mountain system was in identify and the supplied 15-amp fuse was installed, the air compressor immediately came to life and pumped the springs up to 5-psi—the minimum recommended force per unit area. Later the remote was paired with the compressor information technology was game-on. Precise inflation, bleed-off and programmable inflation settings are all at your fingertips. In fact, since the install we've programmed all three savable settings to accommodate each trailer the truck regularly hooks to.
Checking Up On Our Nitto Terra Grappler G2s
Installing the air spring system was an opportune fourth dimension to inspect the Terra Grappler G2 all terrains we've been running since the spring of 2020. Despite having 16,000 miles on them at this indicate, they remain very serenity on the highway and look brand-new. Checking tread depth, the G2'southward still sport 15.one/32" which nosotros consider higher up average, peculiarly when you have into account how much weight they see on a regular basis. We've kept up on tire rotations (5,000 miles at a time) and check inflation pressure level at to the lowest degree in one case a calendar month. With regular maintenance, the pop all-terrains have many more than years left in them.
