When building a car, why not go with the best? Shocks are an important aspect of the suspension that is commonly overlooked. Don't go out and buy just any auto parts store shock when you can get the best at a reasonable price. KYB “Gas-A-Just” shocks are America’s best-selling monotube gas shock. The monotube design is paired with high-pressure nitrogen gas to keep your tires glued to any road surface. This system eliminates the common problem of fading performance (associated with twin-tube construction) that allows the air and fluid to mix. KYB “Gas-A-Just” shocks include a protective outer shell to keep dirt out, self-sealing packing to reduce oil leakage, rubber cushions to protect inside on extreme extension strokes, seamless cylinder to reduce splitting, hard-chromed piston rod to reduce friction, rebound/compression valve to give quick dual-direction response, sintered iron piston for strength, all-weather fluid, floating dividing piston to separate gas and fluid and a tube guard to prevent damage from stones and debris. “Gas-A-Just” shocks are ideal for use with both radial and bias-ply tires.
