Ineos Grenadier Portals completely change how this rugged wagon hits the trail. Massive tires usually create a mechanical nightmare for heavy British off-roaders. Enthusiasts constantly fight terrible driveline angles and broken transfer case joints when installing standard suspension lifts. Finding a reliable way to gain ground clearance requires serious outside-the-box thinking.

Understanding The Ineos Grenadier Portals

Most drivers swap out their factory ring-and-pinion gears to turn taller rubber. Unfortunately, this traditional method amplifies the torque load on standard axles and inevitably causes costly trail breakdowns. By moving the gear reduction directly inside the wheel hub, mechanics can permanently fix this annoying issue. Couch stated: “The big advantage is the gear reduction being done right here in this massive assembly.” The original drivetrain remains completely protected from extreme mechanical strain because the custom hubs handle the extra rolling mass.

Building The Custom Hubs

Solid billet aluminum gives these new carved housings incredible durability on the rocks. Since the kit delivers almost 5 inches of true vertical lift, the factory mounting points require serious reinforcement. Mechanics replace the original steering knuckles with heavy nodular iron pieces to handle these extreme forces safely. As Couch explained: “We do a much beefier knuckle because we add some more force onto the lower portion through here.” Afterward, the team welds a pivoting truss onto the housing to prevent metal fatigue.

Managing Unsprung Weight

Extra unsprung mass naturally plagues any chassis carrying heavy metal boxes at the axle ends. Gaining roughly 60 pounds per corner sounds intimidating on paper. Fortunately, the engineers offset this weight by keeping the original bolt pattern and fully integrating the factory antilock brake sensors. Next, the shop mounts custom 18-inch bead-lock wheels to safely clear the large aluminum housings.

Dominating The Dirt

Advanced engineering pushes the boundaries of modern vehicle exploration. Leaving the factory suspension entirely intact preserves the comfortable ride quality originally intended by the manufacturer. Based on the video, bolting up a set of Ineos Grenadier Portals can transforms your vehicle into an unstoppable rockcrawling monster.
