Castrol synthetic fork oil is a fully synthetic suspension fluid, designed to provide the ultimate damping performance in all road and off-road suspension systems. It’s synthetic base and naturally high viscosity index provide superior anti-fade damping performance over a wide temperature range. Castrol synthetic fork oil allows rapid air release and superior anti-fade performance under the most arduous conditions, such as racing. It also helps eliminate suspension unit ‘sticking’ providing smooth operation of the suspension. • Superior Damping Performance At High Or Low Temperatures • Rapid Air Release For Maximum Anti Fade • Wear Protection Prolongs Component Life • Minimised Metal Sticking For Smooth Operation • Protects Internals Against Corrosion PLEASE NOTE: Picture for illustration purposes only.
