Hello again Chris; the # T68MR is for the severe service kits that fit the 2000-2021 Tundra. These are designed for heavy applications under constant load like a salt spreader. Since you will be using the standard Timbren SES # T45MR the Spacer Kit for Timbren Suspension Enhancement System # T33AV is the correct set of spacers.
