Choosing the right silicone oil makes a noticeable difference when tweaking handling and grip. The HUDY 106366, at 650 cSt, is a heavier option for differential tuning that helps deliver firmer torque transfer. It is one choice among a range of viscosities to suit different setups and conditions.
This weight is favoured for diffs where drivers want reduced slip and a more locked feeling under acceleration. Its consistency supports consistent diff performance across short runs and longer sessions.
The 100ml HUDY 106366 bottle includes a flip top for easy application and neat storage. The capacity suits regular tuners who change settings often without running out quickly.
