Metal Shop Truck Rear End Work

Devin modifies the rear end

Work continued on the rear half of the KBPI Radio Metal Shop Fummins the other day. After the factory 9-inch rear differential was replaced with the Chrysler 14-bolt 11.5", the frame needed to be strengthened to support the new level of torque from the diesel engine. Cross braces were fabricated and welded-into the frame just behind the cab to provide stability.

Changes are also in-progress on the rear of the truck before the bed can be remounted. Devin from ATS was hard-at-work grinding and cutting the sections of the rear frame to accommodate the updated box. Audio Wrap has been placed inside the cab to help deaden the interior noise and make for easier listening with the new Alpine Sound System from Car Toys.


There is still some work to be done on the front-end of the truck and the look will be quite a bit different once all of the updated pieces are back in-place.

KBPI Radio's Metal Shop 7 Truck Rear End

The Fummins Metal Shop Truck now sits on a 14-bolt 11.5" rear end with a custom fabricated 4-Link suspension. The front end has also been updated with heavy-duty springs and rotors from Jazz It Up. Fuel will held in the fuel cell which is now bolted in-place. Due to the torque that the rear end will see from the Cummins Engine and the low-sitting attitude of chassis, the 4-Link System made sense to put on the back. This will do a good job of keeping the wheels planted and update the old style suspension with new technology. Rear airbags will be added by ATS to help finish the overall package.
