Price has been further reduced as it's not selling well. Thank you. This is a T-REV system kit for the Jimny JB64. It's an internal pressure control valve, similar to the NAG valve. Thank you for viewing. This is a T-REV α for the JB64. Please see the Rainbow Auto website for details. I purchased it new from Rainbow Auto for about 72,000 yen and used it for about a month, driving about 500 kilometers, but it didn't suit me, so I'm selling it. I've disposed of the box, so it's not included. The items included are only those shown in the pictures. (I removed it today, so there are no missing parts for installation on a JB64) Thank you.
