Meet the Rock Monster: FJ Cruiser Gets Beadlocked
I spent the better part of three years searching for an aftermarket wheel that not only looked good cosmetically but was designed to meet the rigors of off-road conditions. I’m not sure why, but I’ve always been very picky when it comes to the style of a wheel. Generally speaking it takes a lot to impress me since I find many designs to be unappealing for one reason or another. As such, you can imagine my elation when I first laid eyes on the Rock Monster, a wheel that not only looked good, but was specifically designed with rugged conditions in mind. Hutchinson Industries, the company behind the Rock Monster series wheels, has been manufacturing heavy duty aluminum beadlock and run-flat wheels for the U.S. military for more than two decades. Their product lines are specifically targeted towards emergency recovery and military support vehicles in the field. These wheels have undergone extensive testing and have proven themselves again and again under rather extreme field conditions. Suffice it to say, they are designed to withstand some serious punishment.
Unlike a traditional one-piece wheel, the Rock Monster is a split-rim design where the outer facial portion of the wheel is removable. This two-piece design enables Hutchinson’s proprietary beadlock ring to be installed prior to wheel assembly. Once the beadlock is in place, the wheel is assembled, effectively pinching both the inner and outer tire beads between the respective rims of the wheel. This method for beadlocking is not only high effective, it’s also extremely safe. So safe, in fact, that Hutchinson Rock Monsters are the only beadlock wheel that has been approved by the department of transportation (DOT). Because Hutchinson holds military contracts, they are held to higher standards than traditional wheel manufacturers. As a result, these wheels are produced with extremely tight tolerances. They offer two different sizes of beadlock rings so you’ll need to know what tire you plan to use before ordering, to make sure you get the right size beadlock.

Inchworm Lefty Install: FJ Cruiser Gets a Tummy Tuck
When it comes to modifying the FJ my goal has always been to achieve increased capability without negatively impacting vehicle performance. There’s no doubt that a vehicle designed for hardcore off-roading is going to witness its share of bruises. And the greater the number of modifications, the greater the chances that the stock integrity will be affected. My FJ Cruiser began its life as a daily commuter that saw occasional off-road use. Over the last four years of ownership, the scales have definitely tipped in favor of off-roading. It’s still my daily commuter, but my upgrade priorities now lean towards off-road conditions, rather than worrying so much about what kind of mileage I can achieve. To that end, it’s time to roll back the clock once again, to retroactively discuss one of the best possible modifications available for FJ Cruiser owners.
October of 2009 was a great month for my FJ Cruiser, and probably one of the most significant in terms of upgrades. I had spent the previous month or so analyzing my FJ’s performance characteristics in great detail in an effort to determine my next upgrade path. One of the immediate drawbacks to note was performance on inclines. Although the FJ comes stock with a 2.56:1 transfer case gear ratio, the gearing even in LOW/LOW leaves a lot to be desired when it comes to steep hills. Extremely rocky terrain can also prove frustrating since drivers can find themselves in constant “brake” mode, where their foot never leaves the pedal. On flat terrain, riding the brakes can indeed be an effective method for controlling forward momentum. But on inclines where the surface is loose or slippery, hitting the brakes can lead to disastrous results. The question is, what can FJ owners do to improve this situation?
