Title: Lowering a 1982 shortbed stepside
Post by: truckguy on February 17, 2018, 12:34:27 PM: I want to lower the truck with a 4/6 drop. The front will be spindles and springs (with a HD 1.25" rotor upgrade). In reading about dropping the rear, it seems I'll need an axle flip to get the six inches. I'm not going to use the c-notch kits because I've read posts that show that they weaken the frame significantly and I want to be able to continue to use the truck for hauling and towing. I am OK with a notch as long as it cuts less than half the width of the frame rail. The finite element analysis (FEA) of frame strength after a notch shows that the overall height of the frame is what gives the strength. I haven't seen anyone discussing the mono leaf spring option. They seem like a good choice except for the cost.(https://www.brotherstrucks.com/73-87-REAR-MONO-LEAF-SPRING-SET-REVERSE-EYE-6/productinfo/MLSR087/). Has anyone used a reverse eye mono leaf spring to lower the rear? And if so, what about frame clearance?
