Competition Engineering Adjustable Drag Shocks
These Competition Engineering adjustable drag shocks offer a 3-way valving system to dial-in the extension/compression ratio needed for any track condition. The front shocks have three adjustable ratios of 90/10, 80/20, and 60/40. The ratios for the rear shocks are 70/30, 60/40, and 50/50. These numbers represent the percentage of force required to extend (first number) and compress (second number) the shock. By changing the settings on the front and rear shocks, you can dial-in the car to raise the front on initial launch for weight transfer, and then settle smoothly for a final charge to the finish line.

BDS Suspension NX2 Steering Stabilizers
BDS Suspension offers steering stabilizer kits with NX2 shocks for a variety of applications, including many Chevy, GMC, Dodge, Jeep, Ram, and Ford vehicles from 1973 and up. The stabilizers are available in single (for stock/lifted) or dual inline (for lifted) designs. These components will enhance the handling of your truck or SUV. Installing larger tires can exert additional force on your suspension, but steering stabilizer shocks can effectively reduce bump steer and steering wheel feedback. BDS mounting brackets are constructed of high-strength steel and can be easily bolted on. The BDS NX2 stabilizer uses a pressurized nitrogen-charged twin-tube design with 10-stage velocity-sensitive valving for lightning-fast dampening adaptive to whatever terrain you traverse, on- or off-road. The 2-inch bodied shocks use a large 1 3/8 in. fluon-banded piston, self-lubricating seals and a 14mm hardened chrome shaft to help resist rock chips and corrosion.

Monroe Gas-Magnum Shocks
Monroe Gas-Magnum shocks provide firm control without a harsh ride by using up to twice the fluid capacity of standard 1 in. bore shocks. This all-weather fluid contains special modifiers to reduce friction and ensure smooth rod reaction. The shocks also feature full displaced valving for better range on both the compression and extension cycles, ensuring a comfortable ride. These shocks use a sintered iron piston, which is stronger than traditional metals, to enhance durability for longer service life. Each unit is nitrogen gas-charged for improved ride and handling; reduced aeration helps to maintain tire-to-road contact. Their large 2 in. reserve tube allows for more fluid-producing consistent performance, while their 1 3/8 in. bore offers more lowering pressure than conventional 1 in. bore shocks. Monroe Gas-Magnum shocks are finished off with a 5/8 in. heavy-duty nitrocarburized rod and a special self-lubricating fluid seal to retain gas without excessive wear or friction.
