Product Info
The King Springs Front Coil Springs KDFR-70HDT are engineered for D40 4WD models from 2005 to early 2015, delivering progressive suspension tuning that absorbs bumps and harsh terrain without bottoming out. Built from X5K high-stress spring steel, they are approximately 30% lighter than conventional coils while maintaining a load capacity of 100–250kg, reducing unsprung weight and increasing suspension travel for better off-road performance and ride comfort.
Each front pair features tapered wire progressive rate design that provides smooth resistance across the full compression range, backed by phosphate coating and epoxy powder coating for maximum corrosion protection in Australian bush conditions. Advanced CAD engineering optimises load distribution, making these springs a direct factory-equivalent replacement for worn coils or an upgrade path for vehicles running higher payloads or extended travel setups.
