Have you ever heard the old saying that it's not the fall that hurts, but that sudden stop will ruin your day? Well, we have, and anyone who has ever hit an obstacle a tad too fast or made their rig defy gravity if only for a brief moment knows why that statement rings true. While a nice suspension system will soak up most off-road turbulence, once the uptravel reaches its end, it's important to have something in place to absorb that last leg of impact. This is where the small but powerful bumpstop comes into play.?>
Though bumpstops come in a variety of shapes, sizes, and material types, their primary job is to work not only as a safe stopping point for your suspension system but also as additional damping as the suspension enters its final stage of uptravel. Over the past few decades OEMs have upped the role of the once basic suspension endpoint, and bumpstops now play an active role in most modern suspension systems.
Bumpstops are an extremely integral part of the suspension equation, but often for very different reasons. For most trail runners a rubber or polyurethane bump works great to help the rig have a low center of gravity and prevent oversized knobby tires from peeling off the fenders. On the other end of the spectrum, high-speed rock racers and desert rompers incorporate more tunable and durable nitrogen-charged bumps to help control and damp the impact of the more extreme and long-travel suspensions.?>
Similar to most 4x suspension parts, bumpstops range wildly in price and performance. So to give you a closer look and explanation at these ever important mini suspension members, we've complied some of the most common types and noted their primary advantages.
Factory bumpstops wear out over time, and a quality replacement isn't always available from your local parts house. Luckily Daystar offers a variety of factory replacement and universal bumps. Daystar's bumpstops range from low-profile to progressive-rate and are made of high-impact polyurethane. The company even offers EVS foam bumps that attach to your shock and act as a progressive-spring rate, providing even more cushion during the compression cycle.
