Hey guys,
I just went to reorder some front coil springs for my 89 D250 and they wanted to know if it was Heavy Duty or Super Heavy Duty.
Is there any easy way to tell this?? There are different part numbers for the two springs.
Mine is a 89 D250, Reg Cab, 8ft Bed, 318, 3 spd auto trans., 8 lug wheels.

Thanks

 

There should be a GVW weight rating on the door somewhere or you might be able to use the VIN to find it out from a dealer.
