Yes you can remove some, start with the smaller ones, tow or three of them should help. You can't haul as much weight with leafs removed!

You can also grind each leaf smooth so they ride on each other easyer, or add the teflon poly strips to each leaf. I bought mine from Speedway in Lincoln Ne. It worked great, I went back and added it to the front leafs. The truck is much quieter on rough roads and way smoother riding. Most any speedshop or street rod parts vender lists it in 20 foot lengths. My 37 used 3 roles of it to do four springs.
