Figured I'd add to some of the info here. Been running the RCI for yrs now. In the beginning, ran the alum and differential. Bent them all due to difficult/extreme trails. They all bend! Have changed out the alum to steel. I've even added reinforcement to all skids
Had to cut and reinforce the exhaust section as it will make contact if you dont, and creates a drone sound. Even the support plate that hold it up trys to flatten out to make that plate come up closer.
Engine plate, will make contact on the the front diff.
If you do any long travel to your rear, the drive line will rub the tank skid, even down to the bolt on to the rear diff. Had to remove and cut 3 times so far. The support brackets will bend also, all needs reinforced also.
Under normal trail running, this extreme of reinforcement probably wont need to be needed.
But if you get into some trails like I tend to, this will need to be addressed with any plates.
I can get the tank pictures later when thers light.
