FALCON Sport 2" Lift Shocks 2024-2014 Toyota 4Runner (12-04-21-400-002)

The 2010+ Toyota 4Runner: Falcon Sport 2” Lift Shock Absorber System delivers increased stability and control as well as improved ride quality and comfort both on and off-road. These compact and affordable shocks are ideal for daily driven vehicles.

ZRT - Zone Rate Tuning:

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.

VOD - Volume Optimized Damping:

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.

Falcon’s proprietary Volume Optimized Damping (VOD) features a digressive linear valve that produces quicker ramp up for increased damping volume, which improves vehicle feedback and control during low-speed driving. VOD also improves the shock absorber’s ability to reduce bottoming out at full compression during faster speeds or over uneven terrain.
