This is for a brand new AEV Jeep JK Spare Tire Jack Booster. If you’re running bigger tires up to 37” and you still want to use the scissor jack that comes with your JK, then this is specifically made to work with it and give you the extra height to be able to get the tire off the ground. This sells new for $66 so come get mine and save some money. Cash sale and porch pick up only. If the ad is up, it’s still available. Please text for a quick response. Thanks for looking
