We have been running an 80 Series semi float in the back of my 4619 car since 2014. It has bee very durable considering with only one axle shaft falure. It has never bent which it dam impressive. The goal here is build a full floater with upgraded shafts, ARB. Will bolt in and we will keep the semi floater for a complete spare you could drop in the event of an emergency during a long race like the 1000. All for less than 3500$ Here is said race truck. 1985 Toyota Truck, been running stock class (4600) since 2014.
