Tomei Reinforced Timing Belt – Toyota 4A-GE / 4A-GZE
The Tomei Reinforced Timing Belt is engineered for high-spec tuned engines where upgraded camshafts, high-lift profiles, and reinforced valve springs significantly increase operating stress and heat. Standard belts deteriorate rapidly under these conditions, risking timing inaccuracy and potential engine failure. Tomei’s belt delivers superior strength, heat resistance, and long-term reliability for demanding 4A-series engines.
Key Features
High-saturation H-NBR rubber construction for exceptional heat resistance
Reinforced high-strength glass core for improved tensile stability
Kevlar (Aramid) + Nylon belt surface for increased abrasion and cutting resistance
Ideal for tuned 4A-GE and 4A-GZE applications
Performance Comparison (Vs. Standard Belt)
