KYB 733013 Suspension Strut - Front Left

KYB AGX Adjustable Front Left Strut

The KYB AGX 733013 is a manually adjustable suspension strut for drivers who want more control from their Mazda RX-7 front suspension. It lets you change damping without special tools, making it easier to tune ride response for street driving or track use.

Key Features

• Adjustable performance strut for enthusiast-focused suspension tuning
• Up to 125% more damping force than the original Mazda RX-7 design
• External adjustment without lifting the vehicle or removing the tire
• Precision multi-stage hydraulic valves for a wider performance range
• Seamless working cylinder with a Teflon-coated piston band for a positive seal and longer service life
• Engineered to help vehicles equipped with electronic safety systems such as ESC and ABS
• Front left application for 1986-1991 Mazda RX-7

Product Details

KYB AGX is a performance strut line built around quick damping adjustment. Depending on the vehicle application, the strut uses either an eight-position knob or a four-position screwdriver slot, with both formats delivering the same overall adjustment range. One change affects both rebound and compression damping, allowing the suspension to be tuned for changing road conditions, autocross, or track sessions. Part number 733013 is listed for the front left position on 1986-1991 Mazda RX-7 models, including manually adjustable performance suspension strut applications and AAS conversion use noted by the manufacturer.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Excessive body motion during aggressive cornering
• Soft or inconsistent front-end damping response
• Need for quick suspension tuning between street and performance driving
• Worn front left strut performance on Mazda RX-7 models
• Reduced tire contact and control under changing driving conditions

Installation Notes

For 1986-1991 Mazda RX-7 front left applications, verify suspension type before ordering, since this AGX strut is not compatible with electronically adjustable suspension. KYB recommends replacing the strut mount with part number SM5303 to reduce noise and vibration, and using strut boot SB103 to help protect the new strut from dirt, debris, and salt. Confirm compressed length, extended length, stroke length, and upper mount thread specification before installation.

Quality Assurance

KYB designs the AGX line with velocity-sensitive damping valves and a sealed cylinder/piston design to support consistent operation and longer service life. Part number 733013 is built for the demands of performance-oriented Mazda RX-7 suspension service.
