Bad Leaf Springs?

I have a 2004 Rumble Bee that was lowered by previous owner. It always felt as if the shocks were bottoming out going over a bump. It looks like he never replaced the original shocks and also removed the bump stops. He use to race this with nitrous installed. I replaced the shocks and it still bottoms out. Could the leaf springs be bad? How can you tell? Also can you install helper springs for support when the leaf springs are mounted under the rear axle? Trying to find a simple way to fix this.

Sounds like it has a flip kit. The original shocks are too long and just like you've indicated are probly bottoming out. If you put the same shock back on it'll still bottom out. I would lift the rear and support it with the wheels on ramps so you can get under it. Remove the bottom shock bolt. Push the shock to the close position. Now measure the bottom mounting hole on the shock to the mounting hole it was bolted to. If this is less than the axle travel it'll bottom out.

If it's a flip kit is the frame notched the axle may be hitting the rear frame on good bumps.

Un-bolting the bottom of rear shock and compressing, it measures 5" to top of axle and distance from bottom of frame to top of axle is 4". And possibly having weak leaf springs is giving me no help at all. I also noticed that the previous owner removed the bump stops. Would helper springs solve this or even air shocks or just re-mount leaf springs on top of axle? There's nothing like a lifted truck where you can work under with no problem and lots of clearance. How can I fix this? I took pictures but couldn't figure out how to add them to this message. I'm so frustrated with this.

You have to decide if you want a lowered truck or not. The axle is hitting the frame which is indeed annoying. Do a search on timbren springs. I've posted about the numerous times. Or notch the frame or take it back to stock. It's all your choice.
