5 Way Air Assisted Drag Shock

The 5-way adjustable shock offers high/low speed compression adjustments and high speed rebound adjustment with air assisted low speed rebound for tire control and lowering ride height up to 2 inches.

Technical Advantages

• Adjustable preload on rebound shim stack for starting line conditions
• Air assist allows you to use max rebound at starting line, keeping the shock at a certain position for a certain amount of time before releasing air and smoothing out the ride
• Responsive to higher frequency inputs
• Reduced tire shake
• Consistent and faster 60’ times
• Works off air and a timer- once you get down the track 60 feet or so, you can dump the air to lower the ride height down which adds angle into the four-link resulting in the tires getting more grip
• Lowers ride height up to 2 inches
• CO2, solenoid and timer sold separately

Triple Adjustable Air Drop Shock

JRi Shocks has equipped their double adjustable drag racing shock with a smooth body and an air assist feature to provide racers an added degree of tunability further down the racetrack. Once down the track, the air assist feature allows the driver to dump the air which lowers the ride height, driving the back half of the car into the racing surface, getting the spoiler out of the wind and giving the tire more bite.

Technical Advantages

• Adjustable preload on rebound shim stack for starting line conditions
• Air assist allows you to use max rebound at starting line, keeping the shock at a precise position for a certain amount of time before releasing air and smoothing out the ride
• Responsive to higher frequency inputs
• Reduced tire shake
• Consistent and faster 60’ times
• Works off air and a timer- once you get down the track 60 feet or so, you can dump the air to lower the ride height down which adds angle into the four-link resulting in the tires getting more grip
• Lowers ride height up to 2 inches
• CO2, solenoid and timer sold separately

Eliminator series

AFCO ELIMINATOR twin tube adjustable shocks are built specifically for drag racing. These shocks are available in Single and double adjustable configurations. Furthermore these shocks are available as adjustable stock mount shocks. Contact us for lengths and vehicle compatibility.

Reactor Series

AFCO single adjustable shocks are an economical alternative to the fully double adjustable design. The single adjustment gives you the ability to adjust rebound damping control without affecting the compression damping characteristics of the shock. The rebound adjustment is the most critical in tuning a drag racing setup. This adjustment allows the tuner to dial in the separation of the chassis and keep the tires planted during the critical first 60’ down the track. The shocks are available in stock mounting location configurations.

Big Gun Twin Tube Aluminum Series

The “Big Gun” shocks are specifically valved for high horsepower applications. Both small tire and big tire cars can better control the “hit” to the tire with this series of shocks. Don’t “drive through” your shocks with that big power. Choose this series of shocks for the ultimate control off the line. Rebound and compression adjustable. Make a click and feel the adjustment. Big Gun shocks are available in 4”, 5”, 6”, and 7” stroke configurations.

Big Gun Monotube Aluminum Canister Series

These shocks are specifically valved for high horsepower applications. A larger piston provides superior launch stability. Gas pressure eliminates cavitation and allows shock to recover faster. Double adjustable with a broad range of adjustment. Available in 4”, 5”, 6”, and 7” stroke configurations.

Dominator 4-Way Adjustable Drag Shock

The engineers at AFCO designed the new 4-way shock program with performance and function in mind. This shock series features the same traction enhancing technology found in all AFCO Shocks, but is fully high and low speed adjustable on both compression and rebound damping. Consistency is improved by the recirculating, single circuit valve design. Unlike other adjustable shocks, hysteresis is minimized and remains low regardless of the adjustment position or range. This allows for a wide adjustment range without sacrificing performance. The shock can be configured to fit most coil-over applications. Its compressed and extended lengths are in line with industry standards and the adjustable eyelet and canister position allows for maximum mounting clearance. This series is ideal for everyone from the over-achieving sportsman to the professional racer.

• Fully independent high and low speed adjustments for both compression and rebound.
• All adjustments affect the pressure drop across the main piston.
• Single-circuit, recirculating design allows for large adjustment range with extremely low hysteresis.
• Solid main piston allows for reduced gas charge pressure without the risk of cavitation.
• Nitrogen bladder design enhances response and reduces “stiction” induced hysteresis and eliminates cavitation.
• Compact – compressed and extended lengths comparable to most standard shock lengths on the market.
• Universal mounting design has 32 different options.
• 8 position, indexable gas canister.
• 4 position, indexable body eyelet.
