KYB Excel-G Rear Strut Cartridge for Toyota MR2

The KYB Excel-G 363046 is a rear suspension strut cartridge for 1985-1986 Toyota MR2 models with sealed strut applications excluded. Built on KYB OE assembly lines, this Excel-G replacement is calibrated to restore original ride control, stability, braking response, and handling for the Toyota MR2 rear suspension.

Key Features

  • KYB recommended OEM replacement gas cartridge
  • Nitrogen gas-charged, twin-tube design
  • Triple-lip fluid seal helps reduce oil and gas leakage
  • Vehicle-specific, hand-assembled damping valves manage tire contact, steering response, and body movement
  • Strong strut body and bracket construction helps minimize flex and maintain alignment
  • Supports proper operation of electronic safety systems by preserving suspension behavior as designed
  • Compatible with KYB strut boot SB103 for added protection from dirt, debris, and salt

Product Details

KYB Excel-G is the brand’s OEA-style replacement line, made to return the suspension to its original designed performance rather than change ride characteristics. Part number 363046 uses OE-quality components and application-specific damping calibration to help the rear suspension on the Toyota MR2 respond consistently under braking, lane changes, and everyday driving. This part cross-references Monroe Shocks & Struts 72881 for the same application.

What This Strut Cartridge Helps Address

  • Excessive rear-end bounce or oscillation
  • Reduced stability during braking and cornering
  • Loose or delayed steering response from worn suspension damping
  • Uneven tire contact caused by weak rear control
  • Oil seepage or gas loss from aging strut cartridges

Installation Notes and Tips

Fits 1985-1986 Toyota MR2, rear, recommended OEM replacement; exc. sealed struts. Verify the upper mount thread size of 14X1.50 and confirm compressed length, extended length, and stroke before installation. Inspect related suspension components, and replace worn boots or mounts as needed. For added protection, KYB recommends strut boot SB103.

Quality Assurance

KYB is a major OE shock and strut supplier, and the Excel-G line is produced on the same KYB OE assembly lines using OE-quality components. The 363046 is engineered to restore original vehicle control and handling characteristics for the rear suspension on the Toyota MR2.
