Falcon Rear Shock and Bumpstop Set for 10+ 4Runner

TFX 10+ 4R REAR SHOCK PKG 5 or 6

Teraflex has released a high quality line of shocks and bumpstops for Toyota applications. Knowing their rich history in shock absorber manufacturing and building off-road equipment, these are sure to be a hit. These rear piggy-back reservoir shocks are available with fixed rate damping optimized for on- & off-road driving or optionally available with the Tow / Haul Option which features a three-position Fast Adjust Knob on the shock reservoir that allows the shock to be set for 1. Comfort & Control, 2. Moderate Tow/Haul, and 3. Heavy Tow/Haul settings.

These shocks are for 4Runner's that have 1"-2.5" of rear lift. Also included is a high quality set of micro-cellular "foam" progressive rear bumpstops as well as shock shaft "Roost Guards" to protect the shock shafts from gravel and debris. That's a lot of extra's.

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.


• 2010+ Toyota 4Runner (5th-gen)


• Piggyback shock absorbers 
• Progressive microcellular “foam” bump stops 
• Bump stop cups 
• Roost guards 
• All necessary hardware

Features & Benefits

• Rear piggyback shock absorber pair with fixed rate performance valving or optional Fast Adjust Knobs w/ 3 compression settings for enhanced dampening adjustment on the vehicle
• Optional Fast Adjust rear adjustment settings include: Comfort & Control, Moderate Tow/Haul, & Heavy Tow/Haul
• Shocks include Roost Guards and a Micro-Cellular Foam Progressive Rear Bumpstop Set

Piggyback Shock Absorbers:

• Piggyback design features increased oil & gas capacity vs. monotube or twin-tube designs reducing heat buildup for more consistent performance 
• Piggyback fluid passage design flows 6 times more oil than restrictive reservoir hose designs as well as eliminates common leakage issues found in banjo & swivel fittings

Falcon Truck Shocks:

• All testing done on E-rated tires (worst possible ride) 
• Largest shock body that will fit w/out modifications 
• Negative spring inside shock body eliminates top out clunk, softens tire landing, & reduces body roll & stress on shock 
• Application-specific tuned bump stop reduces bottoming out & body roll 
• High-quality spherical bushings (when applicable) 

All Falcon Shocks:

• Vehicle-specific shock absorbers 
• Race-inspired performance for increased vehicle stability 
• Improved dynamic roll control & low speed damping 
• Dramatic improvement in on-road comfort & off-road performance 
• Optimized fitment for clearance during full suspension travel 
• 2.25” shock body provides optimal performance 
• 6061-T6 aluminum alloy shock body resists wear & protects internal components while providing superior heat dissipation 
• Smooth honed internal shock body surface for long-term performance 
• 3/4” induction hardened chrome plated shaft resists rock damage & corrosion as well as prevents shaft buckling 
• Maximum shaft diameter allows for more precise tuning 
• Hard anodized billet piston 
• 1-piece Teflon bronze piston wear band w/ O-ring 
• Digressive linear piston & base valve technology 
• Volume Optimized Damping (VOD) features a digressive linear piston for quicker ramp up & increased damping volume 
• Inline OGS (Oil/Gas Separator) prevents cavitation 
• Red Line full synthetic shock oil with high viscosity index of 519 for consistent performance across all temperatures & reduced shock fade 
• Synthetic formula also contains special anti-wear & lubricity agents for excellent thermal stability 
• 1,000-hour salt spray corrosion resistance test on all hardware 
• Serviceable & rebuildable (factory serviced) 
• Built in-house at the TeraFlex Falcon Shock Division 
• Patent pending design 
• 3-year warranty


• Do not use tow/haul modes while unladen as the increased rear stiffness could upset the balance between the front and rear of the vehicle, which could lead to loss of vehicle control. 
• Never exceed factory tow/haul ratings.
