Product Info
King Springs Coil Springs Front Pair KTFR-69HD are engineered from advanced X5K high-stress spring steel, a premium material developed for top-level motorsport and now standard across King Springs' passenger and 4WD designs. The progressive coil design uses variable pitch and tapered wire forms to deliver optimised suspension response, with all coils manufactured in X5K material reducing weight by approximately 30 per cent compared to conventional spring steel while maintaining durability and increasing suspension travel. Each spring receives a phosphate base coat for maximum corrosion protection, finished with durable epoxy powder coating to ensure long service life in harsh Australian conditions. Designed using advanced CAD engineering and tested across passenger vehicles, commercial applications and motorsport categories, these heavy-duty front coils deliver reliable performance whether on road, track or off-road.
