Looking to buy the Billet coolent hose clamps from Eddie motorsports and just seeing if anyone knows the upper and lower radiator hose sizes? The heater hoses and 5/8 and 3/4, I just dont have a spare hose laying around to measure. Any help would be greatly appreicated.

Thanks

I just measured my water pump outlet for the bottom hose and it's 2" and the hose looks to be 2 1/2 outside. So I would say 2 1/2" clamp should work.
The top hose measured 1 3/4" inside and 2" outside so a 2" should be fine for them.

Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
