Yup really heavy s.o.b to. Better off as boat anchors. Great for light offroading but are known for breaking a lot under hard play. I had great luck with the 1rst one I had but i was light playing with it, but when I got hard into floor jamming holes or ripping up and down trails the 2nd 203 didnt last long.

x2. i had one in the gold truck, i didnt like it because it was full time. which means no doughnuts, unless you get lockouts, or a part-time kit.

how light was the truck? gears? tires? the weight of moving parts has alot to do with it

i have a 203 still in my truck, we put a part time kit in it and put lockouts on the front, i will say that the 2 low in addition to the 4 low is nice, but the total gear reduction you get with the 203 SUCKS i have a 208 that i been planning to swap out, but haven't gotten to yet... to make a long story shorter, the axle swap i did (went form 3.08 to 4.10) still gave me less total gearing than if i woulda left my old axles in and just changed teh case... they work and do their job... but that's about all i'll say for teh 203s...
