Awesomatix OR13V - Main GD2B Case O-Ring

The Awesomatix OR13V is a precision Viton O-ring engineered specifically for the main GD2B differential case on Awesomatix touring cars and pan cars. This small but critical component creates the seal that keeps your diff oil where it belongs while preventing contamination from track debris and dust. Viton material offers superior heat resistance and chemical stability compared to standard rubber O-rings, which means it maintains its sealing properties even during extended main events when differential temperatures climb. The OR13V holds up to synthetic diff oils without swelling or degrading, giving you consistent diff action from the first lap to the checkered flag. When you're rebuilding your GD2B differential or notice any seepage around the case, replacing this O-ring restores that factory-fresh seal and protects your precision gears from premature wear. It's one of those maintenance items that experienced racers keep in their spares kit because a fresh seal takes just seconds to install during a diff service and prevents the headache of oil leaks mid-race weekend. For anyone running Awesomatix platforms with the GD2B differential system, the OR13V is an essential spare that ensures your drivetrain stays sealed and performing at its best.
