KYB AGX Adjustable Gas Shocks for the 1999-2005 Miata Front continue to be a popular choice for Miata owners looking to replace old, worn shocks. Easy-to-adjust once installed, these KYB shocks offer a significant performance improvement over the stock shocks.
Fitting Note: The position of the adjustment knob on these shocks conflicts with the Racing Beat Sway bar (PN 54103). The slighly longer Racing Beat bar and the raised knob on the AGX shocks compete for the same space and will likely make contact with each other. For his reason the use of the Racing Beat Sway Bar (54103) is not recommended for use with these shocks.
1. 4-way Manually adjustable multistage damping.
2. Adjusts from street to track in seconds.
3. No need to lift vehicle or use special tools.
4. Competition grade engineering and construction.
Multistage valve compression enables the shock to adjust to driving conditions automatically. Under gentle road conditions, the valving allows the shock to travel freely for maximum ride comfort. As conditions get rougher, the shocks are compressed faster. The valving responds instantly, to make the shock response firmer, maintaining tire contact and vehicle control.
Sintered iron pistons and guide rods
Sintered metal provides far greater strength than traditional metals, extending shock life and durability.
Micro-smooth, hard-chromed piston rods
KYB has the smoothest hard-chromed rods in the business for extra-long life and reliability.
Seamless cylinders and eye rings
Most shock cylinders & eye rings are made from flat metal and welded at the seam. KYB cylinders and eye rings are extruded as seamless cylinders, eliminating weak points created by welded seams.
Multi-lip seals / self-sealing packing
KYB uses a triple-lip oil seal to keep the oil in and contaminants out.
Patented check valve
KYB uses a special check valve to minimize foaming caused by the mix of oil and gas inside the shock. This helps maintain reliable performance, even under tough conditions.
Fast on car adjustment
Convenient external dial or slot at top of rod (depending on model) allows for simple hand adjustment of the damping forces for street, cruising, or high speed driving. Eliminating the need to remove parts or lift the vehicle.
