Take your JZ build to the next level with the Ichiban Engineering Billet Rear Main Carrier, engineered exclusively for Toyota 2JZ and 1JZ engines. Precision-machined from premium billet aluminum, this carrier delivers unmatched strength, durability, and sealing reliability—far beyond what the OEM component can offer.
 
Designed for high-power applications, our carrier features a recessed provision with a heavy-duty circlip (included) to lock the rear main seal firmly in place. This eliminates the common issue of seals being pushed out under crankshaft movement or high crankcase pressure, ensuring long-term leak prevention. Since replacing a rear main seal requires gearbox removal, it’s critical to get it right the first time—our solution provides the peace of mind serious engine builders demand.
 
Whether for street, drift, or drag racing, Ichiban Engineering’s billet rear main carrier is a must-have upgrade for anyone pushing the limits of the JZ platform.
