KYB AGX Rear Left Suspension Strut for Subaru Impreza

KYB AGX 734037 is a manually adjustable suspension strut for the rear left position on select 2002-2003 Subaru Impreza models. It gives drivers a direct way to tune ride control without special tools, making it a practical choice for street use and track-focused setup changes.

AGX Adjustable Ride Control

The KYB AGX line is built for enthusiasts who want to change damping quickly and repeatedly. Depending on application, adjustment is made with either an eight-position knob or a four-position screwdriver slot, and one setting changes both rebound and compression damping. On this Subaru Impreza rear left strut, the design can add up to 125% more damping force than the OE baseline.

  • Manually adjustable performance for the rear left suspension
  • Externally adjustable without removing the tire or lifting the vehicle
  • Precision multi-stage hydraulic valves for a wider damping range
  • Seamless working cylinder with a Teflon-coated piston band for sealing and durability
  • Engineered to work with vehicles using ESC, ABS, and related safety systems
  • Compressed length: 14.96 in; extended length: 23.81 in; stroke length: 8.85 in
  • Upper mount type: 14X1.50

Fitment and Application Details

Fits 2002-2003 Subaru Impreza, rear left. For WRX rear AGX installation and adjustment, the rear seat cushions must be removed and reinstalled per factory specifications. KYB recommends new strut mounts, part number SM5244, to reduce noise and vibration, and a KYB strut boot, part number SB102, to help protect the strut from dirt, debris, and salt. This part number is 734037.

Common Problems This Strut Helps Address

  • Excessive body motion from worn rear suspension damping
  • Inconsistent handling during street driving or performance use
  • Reduced tire contact over rough or changing road surfaces
  • Noise and vibration associated with aged strut components
  • Loss of ride control from a rear left strut that no longer matches OE performance

Installation Notes and Quality Assurance

Install according to the vehicle-specific instructions packed with the AGX strut. KYB recommends replacing the strut mount and adding a strut boot during service to help preserve ride quality and protect the new strut. KYB AGX 734037 is part of the AGX performance line, which is designed for drivers who want adjustable damping control on a Subaru Impreza without changing the vehicle’s suspension layout.
