Upgrade your vintage Toyota 4WD suspension with premium Bilstein B6 4600 front and rear shock absorbers, engineered for the Toyota Hilux and 4Runner 1983–1990 4WD models with leaf spring front and rear and standard ride height. The B6 4600 series is a direct-fit performance upgrade over OEM shocks — providing improved handling, better road control, and enhanced comfort both on-road and off-road. Built with Bilstein’s high-gas pressure monotube technology, these shocks resist fade and maintain consistent damping response under heavy loads or rugged terrain. Featuring velocity-sensitive digressive valving, they respond instantly to changing surface conditions, delivering enhanced stability and confidence behind the wheel. This set is ideal for owners who want to preserve classic truck ride height while dramatically improving suspension performance without modifications.
