Driveshaft Tunnel & Battery Disconnect
The Drive shaft tunnel is complete. Also, the Battery disconnect has been mounted along with the fire system plunger which will be plumbed to the fire bottle. In event of a fire, the activation of the fire system will shut off power to the vehicle.
Here’s a shot of the sheetmetal under the rear of the truck. Most of the other images I have posted fail to show this part, so here it is.
Due to Barb Nesbitt’s unfortunate accident on August 8th 2010, the NHRA has mandated a Driveshaft tunnel rule for all vehicles that have had the factory floor removed.
Beginning Jan. 1, 2012 all full-bodied vehicles, where the OEM floor has been removed, each end of driveshaft must have round 360-degree driveshaft loops within 6 inches of U-joints. Additionally, driveshaft must be covered by
360-degree tube, covering the front U-joint and extending rearward a minimum 12 inches. Minimum thickness of tube is .050-inch chromoly or titanium. Driveshaft tube must utilize a minimum of four attachment points to the chassis, either bolted with minimum 5/16 SAE bolts or welded or 1/4-inch push/pull pins.
You can follow the links below for more info on her accident and what happened. It’s kind of scary because I really didn’t think much of it with having front and rear driveshaft loops. When I first heard of this accident Pete and I talked…It was a no brainer to get one installed! And what do you know, the NHRA thought everyone should have one too.
