J Replace OE Replacement Lower Oil Pan - Lexus GS300 IS300 01-05 1JZ 2JZ Front Sump

A dented lower oil pan is one of the most common casualties of a lowered 1JZ or 2JZ car, and because the lower pan hangs below the upper pan it takes the hit first. The J Replace OE replacement lower oil pan for the 2001-2005 Lexus GS300 and IS300 matches OEM part number 12102-46040 and fits the front sump 1JZ and 2JZ configuration used in those cars and other front sump applications.

Why swap the pan rather than hammer it out

A dented pan reduces clearance to the oil pickup and can starve the pump under hard cornering or braking. Beating it back into shape rarely restores the original depth and often cracks the metal. A new lower pan restores the factory pickup clearance and gives you a fresh sealing surface at the same time.

Install notes

Have fresh sealant on hand for the lower-to-upper pan joint, clean both surfaces completely, and plan an oil change as part of the job. This pan also suits 1JZ and 2JZ swaps into other chassis where the front sump layout is used.
