DO-Luck 2JZ Chromoly main cap + Billet ladder frame

Tuning parts for the TOYOTA 2JZ-GTE engine. The original, individually fixed crank caps are not used. This product connects a chromoly heat-treated main cap (high hardness) to a billet ladder frame made of 2017 duralumin with hard anodizing , creating a unified structure. Installation improves durability and torsional rigidity. Because it is manufactured in an undersized configuration, line boring and metal grooving are required for installation. ARP main stud bolts are required separately. < https://www.do-luck.co.jp/product/1578 > *If using a stroke-up crank or a thick connecting rod, there is a possibility of contact with the ladder frame.
