Product Details

KONI STR.T shocks restore factory-fresh ride quality and control to the 1989-1991 Avanti with a fixed-valving tune that's slightly firmer than OE. Designed to work with stock springs or mild lowering springs (up to roughly 35 mm), STR.T is the ideal upgrade for owners who want a more composed daily driver without moving into adjustable territory.

Each damper uses KONI's long-life twin-tube design with hardened chrome rod and durable seals, delivering consistent damping for many years of street duty. Backed by KONI's lifetime warranty on workmanship.

Features

  • Direct OE replacement: bolt-on fitment with stock hardware
  • Slightly firmer valving than OE for sharper handling response
  • Compatible with stock springs or lowering springs up to ~35 mm drop
  • Twin-tube hydraulic design built for years of street service
  • Made in the Netherlands by KONI
  • Backed by KONI's lifetime workmanship warranty
