Important Notes

These trucks were manufactured with and without top-mounted overload springs on the rear leaf springs. A top-mounted overload is an extra leaf separate from the pack that is set above the main leaf. You will need to identify which you have before ordering. If your vehicle is equipped with a carrier bearing, you will need to order 123402 in the accessories section.
