Dimensions for the Springs in the Timbren Suspension Enhancement Kits for a 2013 Chevy 3500HD Diesel

Question:

Do you have dimensions for the Timbren #GMRCK25D AND GMRTT35D? I have a 2013 Chev. 3500HD diesel with a Lance slide in camper and am trying to decide which one to use.

Once installed, the double convoluted springs from the Timbren SES Kit, # TGMRCK25D, will sit 5-3/16 inches below the jounce bumper holder on the frame. The outer diameter of these springs is 4-5/16 inches.

The single convoluted springs from the Timbren SES Kit, # TGMRTT35D, are only 3-9/16 inches tall, but this kit also includes a 1 inch spacer, so it will sit 4-9/16 inches below the jounce bumper holder on the frame (see photos). The outer diameter of these springs is 4-1/4 inches.
