Complete your driveline: Our main proposal is the separately quoted Perfect Tuning custom one-piece 1350 driveshaft, configured for your transmission/output flange, differential flange and installed measurements. A GS430 automatic propshaft is only a possible alternative after fitment review; it is not the default recommendation or a sourcing requirement.
Fitment: Aristo JZS160/JZS161 and Lexus GS300. Aristo JZS147 requires a crossmember modification. The transmission, controller, shifter, transmission fluid, oil pan and external oil cooler are not included.
Complete your swap: Browse the optional products below. Confirm transmission-specific compatibility before ordering.
