These are our rear short stroke KYB AGX shocks. The very same model shocks that were on my car when Keiichi Tsuchiya drove the car at Horse Theif Mile!
Direct bolt on, short stroke and adjustable for damping.
These have an excellent damping range for sportier spring rates. Best for cars running 2" lowered or more.
Damping is easily adjustable via a dial on the outside of the shock.
