The center leaf spring on the driver's side broke, so I need to replace my leaf springs. Going online, I see many different products, yet I don't know how to compare them. I see lifts of 1.5" - 4". Warranties are all over the place, from nothing to lifetime. I don't know what is stock on this truck, and the OEM part #s are discontinued. I'd appreciate any help you can offer to help me choose replacement springs. It doesn't look like 2.7 engine, Xtra cab and manual transmission affect the choice.
