Question:
I need to replace the 4 leaf springs on my travel trailer. The current leaf springs are 25 1/4 4 leaf double eye. I have had 2 break and had to do a road side replacement. 5200lbs axles and was wondering should I go back with the 4 leaf or go up to the 5 leaf spring? Part numbers Im looking at are as follows, e 34sr and e 44sr. Thank you for your assistance

Expert Reply:
Kevin, the only difference between a 4 leaf spring # e44SR and a 5 leaf spring # e34SR is that the 4 leaf spring will use slightly thicker leaves, and is 1/8 of an inch shorter, so the difference between the two springs are pretty negligible in my opinion.
So with that said, I'd suggest going up to the 5 leaf springs # e34SR instead. Especially since you mentioned that you've already had two break, which makes me think they might be getting overloaded.
