The MarTec LLC Toyota Solid Axle Swap (SAS) Crossmember is the definitive, heavy-duty structural foundation engineered for builders converting their independent front suspension (IFS) truck to a live solid front axle. This multi-functional link crossmember completely replaces your weak factory stamped-steel transmission crossmember, providing ultra-strong integrated lower link suspension pockets to mount a custom 3-link or 4-link front suspension geometry.
Intelligently designed for custom fabrication shops and driveway builders alike, this crossmember utilizes your factory transmission mount location to establish perfect positioning on the frame rails. Once bolted up to locate center, simply square it up from front to back and burn it into the frame.
Premium Engineering Features:
  • Heavy-Duty Multi-Gauge Construction: Precision laser-cut, CNC-formed, and heavy-duty welded in the USA from premium 3/16” and 1/4” HRPO mild steel plate.
  • Modular 3-Piece Serviceable Design: Features a fully removable center section. This allows fabricators and trail techs to drop and service the transmission or transfer case without needing to unbolt or disassemble the front suspension links.
  • Pre-Sized Link Pockets: Engineered with an industry-standard 2-5/8” mounting width to fit popular heavy-duty rebuildable suspension joints (such as Johnny Joints or Duroflex ends) utilizing robust 3/4” Grade 8 bolts.
  • Perfect Frame Interlocking: Precision-machined to a clean 36-1/4” total outer mounting width, slipping flush inside factory Toyota frame rails to minimize alignment gaps before welding.
  • Complete Hardware Kit: Package includes all high-tensile Grade 8 assembly hardware required to securely bolt the crossmember sections together.
Vehicle Application & Fitment Guide:
This heavy-duty fabrication crossmember is engineered to adapt cleanly to the frame geometry of the following mid-size Toyota V6 platforms:
  • Toyota Tacoma (V6 Models): 2005–2023+ (2nd & 3rd Gen)
  • Toyota 4Runner (V6 Models): 2003–2024+ (4th & 5th Gen)
