Hello Graham, thanks for reaching out. Both the parts you mentioned, the Timbren # T54KV and # TASR5200S03 are 5,200 lb axle-less systems. The difference is the # T54KV is designed for off-road applications with offroad tires while the # TASR5200S03 is designed for regular on-road use. So the difference would be how the suspension flexes and handles those situations. Aside from that they are both the same spindle, same 4" lift and 5-bolt brake flange.

Were you thinking of doing a single or tandem axle setup? Adding brakes too?

It'll be a tandem with drum brakes on both axles. Dual 5200lb Timbrens are a bit oversized for the DIY trailer I'm building but my itemized list for weight is currently at 4500 lbs including a full water tank and I'm sure there will be an extra 300-500 lbs of unaccounted for weight by the time I'm done building if not more so 5200lb axles make more sense. I don't plan on putting super large tires on and was eyeing the 15" 235/75R15 Loadstar KE28JR wheel and tire combo you guys have.

@Graham Sounds like the 5,200 would still make sense in that case since you will be adding all that extra weight. Just choose your axle depending if you will primarily be driving on-road or off road. Good choice on the tires too. Here are the brakes and hubs I recommend to go with it: - etrailer Electric Trailer Brakes - Self-Adjusting - 12" - Left/Right Hand - 5.2K to 7K # AKEBRK-7-SA - Easy Grease Trailer Hub and Drum Assembly for 5.2K & 6K Axles - 12" - 6 on 5-1/2 - Pre-Greased # AKHD-655-6-EZ-K
