I have the OME HD front coilovers and Leaf packs with 2 additional add a leafs. The ride is as it should be, stiff yet extremely flexible. no sag after a year and can handle any load thrown at it. At first the leafs squeak but they eventually quiet down. I am in the process of adding a PRG 1.5"...
Contact motorsport-tech for a quote on custom ones. I have a M1102 and I have two options, custom adapters or purchase aftermarket 17" rims for the trailer and same rims but 16" for my truck
