Traxxas Backplate/ 20 x1.4 mm O-ring (for engines with starter) (TRX 2.5 2.5 R 3.3) TRA5274.
Ensure peak engine performance and reliable starts. This genuine Traxxas backplate and 20×1.4mm O-ring provide an essential airtight seal for your TRX 2.5, 2.5R, or 3.3 nitro engine with a starter, preventing performance-robbing air leaks.
A worn backplate or O-ring compromises engine compression, leading to inconsistent tuning and difficult starting. Replacing these components restores proper sealing, ensuring consistent fuel draw and maximum power delivery for your compatible Traxxas nitro engine.
