2004 Toyota 4Runner Buildup - 4Runner Fortification

Time goes quickly. It's been about a year since this 4Runner was transformed from a mild-mannered stocker into the machine it is today. No rig is ever left completely alone, so we've been refining the 'Runner ever since.


Last time we showed the 4Runner, we were in the thick of a custom Mastercraft seat installation. We'd finished the mount for the second-row seats and had attempted to adapt the front seats to the stock seat sliders. Unfortunately, the stock sliders were too tall and the resulting seat height had our noggins too close to the roof. We started over, custom-building a new set of mounts and designing them around Mastercraft's 6030 seat sliders. The second time was the charm, as we're now sitting at stock height where we wanted to be.

Our rear shocks needed some attention, as many miles of high-speed running in 4WD had pelted the rear shocks hard enough to chip the shafts. Leaking rear shock oil announced the problem. Thankfully, Sway-A-Way offers replacement parts and upgraded rear shock shafts.

If you've ever peeked under the back of a 4Runner or FJ Cruiser, you know how flimsy the stock rear suspension links are. The lower links are a decent diameter, but the wall thickness is lacking. The stock lower rear links are very easy to bend. The upper links aren't much thicker than a pencil (no joke) so they're also, literally, weak links. The rear track bar has a decent wall thickness, but like the rest of the rear suspension links, it pivots on rubber bushings that bind up and don't allow the suspension to move as it should.

Suffice it to say that our fortified 4Runner is more fun than ever.
