Part III: Bumpstops 101
With the frontend of the 4Runner newly fortified, it was now time to turn attention rearward. A pair of Sway-A-Way bumpstops, Kartek bumpstop mounting cans, and Synergy Suspension strike pads had been patiently waiting since this upgrade’s inception.
In contrast to the ready-made Total Chaos shock hoops we’d used up front, the bumpstop mounts were somewhat uncharted territory. Even though the Kartek bumpstop cans and the Synergy strike pads are ready-made items, the final mounting system and mounting position of the bumpstops was going to require some custom work.
Why go to all the trouble? Hydraulic bumpstops offer progressive suspension control that stock-style rubber or urethane bumpstops can’t match. And, they act in tandem with your existing shocks, reducing the loads and the operating temperature that the shocks experience.
Anything else? Hydraulic bumpstops are like bypass shocks in the sense that they offer position-sensitive suspension control. Bypass shocks provide the ultimate in tunability, but they’re physically larger and they’re more expensive than hydraulic bumpstops. If there’s not enough room on the vehicle or in the budget, consider hydraulic bumpstops in place of bypass shocks.
