SFA Conversion Budget and Parts Planning

Editable, honest BOM. Categories are seeded — prices are yours to fill in as you get real quotes.

What we deliberately don’t do

We do not populate this worksheet with fabricated market prices. Used-axle, gears, and steel pricing move constantly and vary by region. A pretend-precise total gives false confidence.

Hidden costs to plan for

  • Engineering review or inspection fee.
  • Alignment (may require a shop equipped for solid axles).
  • Driveshaft balancing and rebuild.
  • Proportioning valve or brake-line rework.
  • Insurance re-rating.
  • Downtime cost — a work vehicle off the road has a real business cost.
  • Contingency (10–20% minimum).
