any good suggestions on getting the rear end on a 40 ford coupe lower to the ground without using air ride. . triangulated 4 bar with coil over shocks maybe/ (what #rating on coil springs)... parallel leaf kit? (what kit works best).. ill be using an 8" ford rear.. i used parallel leaf kit years ago but had to use 4" lowering blocks and it still wasn't low enough... any ideas and or pics would be appreciated
This is a Chassis engineering parallel leaf kit with a 3" lowering block I also de arched the main leaf a bit. If you use this kit but modify it by moving the front hangers inboard and raise them up mounting them inside the frame rail rather than to the bottom of the frame rail, you will get about this low without any blocks.
Here's a coupe different ways: The 39 coupe was lowered in the rear by removing the top 3 leaves and using 46 shackles. Spacers were machined to make up for the missing leaf thickness This 39 a tudor had what appears to be 2 leaves removed and the spring eyes on the main leaf bent up Sent from my SM-G920V using The H.A.M.B. mobile app
Man that spring looks pretty sketchy bent like that. I wouldn't do that on purpose. Looks like a good way to help the spring break.
If the spring shop knows what they're doing, it will work. The one that I used to work at could, and did this. It envolves heating it, bending it, quenching it correctly, and retempering the end. But we had a furnace and made leaves from raw stock all day, every day. Plus some guys that knew their shit. I ran one on the front of my roadster for probably 10 years.
Flattening the rear crossmember 5 " creates a possible collision between bottom of frame and leaf pack, the result being a bent spring. WEED'ETR spring is the answer.
I make a reverse eye main leaf for 37-40 Fords now and longer shackles through Old Yankee. I just put together a new rear spring set up using a reverse main. I also de-arched the spring 2"
