This week I completed the installation of new front and rear leaf springs on my B-4-B. This afternoon I took it for a spin to experience the results. What a huge difference the new springs and shackles made! I ordered the springs from Betts Spring in Fresno, CA (available in standard or heavy duty configurations, based on original Mopar specs). They have been making springs since 1868. I dealt with Sam Holmes who was a delight to work with. Mounting hardware came from Eaton Detroit Spring (shackles, shackle grease seals, and U-bolts. DCM provided spring pins (which take 3/8”-24 grease zerks, by the way). Yes, I had to deal with three suppliers, but the results were great!
