A leaf spring spreader assembly comprising a tubular frame ( 20 ) having a V-shape with legs ( 22 ) extending in opposite directions from an apex ( 24 ) to a collar ( 30 ) welded to each of spaced ends with a screw ( 32 ) disposed in telescoping relationship with and extending axially out of each leg ( 22 ) to a plate ( 42 ) for engaging the end curl ( 34 ) of a leaf spring. A nut ( 36 ) has radial holes ( 38 ) for receiving a round rod to rotate the nut ( 36 ) for reacting with the collar ( 30 ) for moving the screw ( 32 ) relative to the frame. A bearing ( 40 ) is disposed about each screw ( 32 ) for transmitting thrust loads from and facilitating rotation of the nut ( 36 ). A tension spring ( 52 ) is pulled through the tubular frame ( 20 ) and connected to the second screw ( 32 ) and released to pull the inner ends of the screws ( 32 ) together to retain the nuts ( 36 ) in engagement with the bearings ( 40 ) to maintain the components together.
