The 2007 and up Toyota Tundra: Falcon Sport Tow/Haul Leveling Shock Absorber System pairs monotube front shock absorbers with adjustable piggyback rear shock absorbers. The rear shocks feature a three-position Fast Adjust Knob that allows the driver to select from Comfort and Control, Moderate Tow/Haul, and Heavy Tow/Haul settings.

Zone Rate Tuning (ZRT) manipulates the factory linear-rate spring tuning to produce three distinct performance zones with a more exaggerated spring curve to tackle various driving conditions.

An internal negative-rate spring offsets the factory spring's preload while in the Extension Zone. This eliminates top out clunk and shock stress at full extension, while softening tire landing and reducing body roll on impact during aggressive driving.

The factory spring rate is unaffected in Drive Zone for a comfortable and controlled ride. A provided progressive microcellular bump stop effectively retunes the spring rate while in Compression Zone to reduce bottoming and body roll during aggressive driving.

Falcon Shocks' proprietary Volume Optimized Damping (VOD) features a digressive linear valve that improves vehicle feedback and control during low-speed, high-speed, and off-road driving. As the piston compresses and rebounds, the valve restricts oil flow creating a damping effect.

VOD produces quicker ramp up for increased damping volume, which improves vehicle feedback and control during low-speed driving. Additionally, VOD improves the shock absorber's ability to reduce bottoming out at full compression during faster speeds or over uneven terrain.

Traditional velocity sensitive shock absorbers react quickly during low speed driving causing excessive head toss on rough terrain - or even driveways. Conventional damping then firms up during faster speeds resulting in a jarring ride.

With Volume Optimized Damping, stability and control are maintained throughout all driving conditions.
