The Value of Bumpstops
We write all the time about hydraulic bumpstops around here, and I've ridden in several bumpstop-equipped trucks, but this was the first time I experienced a back-to-back apples-to-apples comparison of what a difference hydraulic bumpstops can make.
My personal '04 4Runner is equipped with a Total Chaos long-travel front kit that uses Sway-A-Way coilovers and boasts 13 inches of travel. As mentioned earlier, Will Browne's 4Runner uses a Total Chaos long-travel front kit that also has 13 inches of front travel. Will has Fox coilovers up front, but he also has a pair of Fox hydraulic bumpstops along for the ride.
It's a similar story for the rear suspension. Browne's 4Runner has hydraulic bumpstops and mine doesn't.
We drove on the same terrain on the same day. This was in the Hungry Valley OHV area near Gorman, California. Side note: we went during the week when it was safe to be going fast on these trails. On the weekend it's a bad idea to be going fast in a truck in Hungry Valley because there are lots of dirt bikes and quads running around. Back to the main point. Browne made quick time on me through the rough. When the 'bumps were mellow our speeds were about equal, but when the big stuff came I had to slow down to avoid harsh bottoming and potential truck damage.
Sitting shotgun in Browne's 'Runner, the value of hydraulic bumpstops was glaringly obvious. There was much, much more control during hard landings and big hits. With the hydraulic bumpstops, it was possible to hit the gas in places it wasn't safe to without them. They made that big a difference.
Hydraulic bumpstops are offered by Sway-A-Way, Fox, King, Bilstein, Light Racing, F-O-A, and Fabtech.
Guess what's next on my list?
