Pro Form Fab suspension parts for diesel trucks that tow heavy or make more power. We stock traction bars, fixed and adjustable 4 link upgrades, long arm upgrades, control arms, leveling kits and rear lift blocks for Ford Super Duty, OBS Ford, Excursion, Dodge Ram and Chevy and GMC HD trucks.

Which Pro Form Fab Part Do You Need?

  • Traction bars stop axle wrap and wheel hop when you tow, haul or launch hard.
  • 4 link and long arm upgrades upgrade the front suspension links for better control on leveled and lifted trucks.
  • Control arms are stronger replacements for the factory arms on Ram trucks.
  • Leveling kits and lift blocks raise the front or rear to level the truck or make room for bigger tires.

Want the full breakdown? Read our Pro Form Fab suspension guide. Shop more parts for your truck: Powerstroke parts, Cummins parts and Duramax parts.

Not sure what fits? Send us your VIN or call 865.640.2097 and we will match the right part.

Pro Form Fab FAQ

Do I need traction bars?

If you tow heavy or run more power, traction bars cut down axle wrap and wheel hop. They are one of the most common upgrades on diesel trucks.

Which Pro Form Fab kit fits my truck?

Each kit is built for a specific make and year range, shown in the product title. Match your truck's year, or send us your VIN and we will match the right kit.

Should I get a fixed length or adjustable 4 link?

Fixed length kits are the simple bolt on choice for most trucks. Adjustable kits let you fine tune axle position and caster, which helps on lifted trucks.
