Power Safe SBS145F batteries, 145amp hours each, and 100lbs each. Made in the USA and typically used for higher end solar setups, they have a 10yr expected life. | Perfect use of the old air conditioning condenser mount location, just required a little beefing up to carry the extra weight. With these installed I can remove the heavy steel plates that were installed on the backside of the front bumpers to assist in handling. | Drivers side rear air bag lower mount, the tube structure is 1"x2"x1/8" and then plated both top and bottom with 1/8". Bottom plate is welded both inside and out. Gusset is 1/4" plate. The swing arm attachment is 3/8"x4" flatbar. | Access hole in the bottom plate allows you to install the air bag mounting hardware | ||
Fabrication on all the rear air bag mounts is complete, I can reattach the shocks and install/plumb the airbags now. | Coat of paint and airbag installed, I'll wait until I compress the suspension to attach the bottom of the airbag. | Passenger front air bag upper mount in work, cleaning the under coating off was the worse part of this.. | this is inside at the top of the wheel well and attaches to the top of the upper air bag mount spreading the load and reducing any transverse movement. | ||
Fabrication complete on the passenger front. you can see the old upper shock mount behind the new structure, I was able to weld them together to further increase rigidity. | There were a lot of backside welds that you can't access, that's why I had to step it out a couple inches and use a combination of mechanical and welded joints. | Passenger front complete, new upper shock mount had to be made for relocation, lower is the factory mount re-positioned and reinforced. | Broke out my new hydraulic crimper and got busy; house batteries fully wired and connected...leads from the batteries to the inverter are 4/0 and were a SOB to route! | ||
