Hello, I have a 2017 E-Z-GO Valor gas cart with back seat. Added a tag-a-long with one more seat. When I have 4 people on the cart and 2 on the tag-a-long going up hill the front wheels come off the ground. Back end of the golf cart sags. I seen a golf cart this weekend with 4 coil over shocks and no leaf springs. I have factory 4 leaf springs right now. Was looking to get new one with different shocks for a better ride. Anyone got any ideas that you could help me with. Everyone that rides on my cart says it really bumpy and on the tag-a-long guy told me he couldn't drink his beer.
