• Can add up to 125% more damping force on the Mazda RX-7
• Externally adjustable without lifting the vehicle or removing the tires
• Eight-position knob or four-position screwdriver slot, depending on application

• Engineered to work with vehicles using electronic safety systems such as ESC and ABS

Product Details

KYB AGX is the adjustable performance line from KYB, built for drivers who want more control than a standard OE replacement can provide. Part number 741025 uses velocity-sensitive damping response to react quickly to changing road and driving conditions, helping maintain tire contact and vehicle control. On the 1986-1991 Mazda RX-7, this rear strut is listed for manually adjustable performance suspension use and for adapting AAS to non-AAS suspension configurations where noted in the fitment data. This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

What It Helps Address

• Excessive rear suspension softness during aggressive driving
• Reduced damping control from worn OE-style struts
• Need for quick ride tuning without removing tires
• Inconsistent handling response on street or track
• Rear suspension setups that need more damping adjustment range

Installation Notes and Tips

Fits 1986-1991 Mazda RX-7, rear. Confirm whether the vehicle uses electronically adjustable suspension before ordering, since one listed application is not compatible with electronically-adjustable suspension. The AGX adjustment is made externally, so ride tuning can be changed after installation. KYB recommends a strut boot, part number SB107, to help protect the new strut from dirt, debris, and salt.

Quality Assurance

KYB designs the AGX line with precision hydraulic valving, a seamless working cylinder, and a Teflon-coated piston band to support consistent damping and longer service life. Part number 741025 is built for the Mazda RX-7 rear suspension application listed above.
