Chassis Fabrication & Welding in South Dakota
Chassis work is where shortcuts kill trucks - and sometimes drivers. We TIG and MIG-weld structural steel to AWS-quality standards, repair rusted frames with full plate-and-fish, stretch frames for crew-cab swaps, and build custom chassis from scratch for restomods and racers. Roll cages, tube chassis, traction bars, link suspension brackets - anything that needs to hold under load gets built like your life depends on it. Because somebody's does.

The 1776 process
- STEP 01
Assess the chassis
Truck on the lift, full inspection. We mark every weak point.
- STEP 02
Engineer the fix
Drawings, material list, weld plan. You approve the scope.
- STEP 03
Cut, fit, weld
Old steel cut out, new plate or tube fit, structural welds laid in.
- STEP 04
Verify & finish
Inspection, paint or coat, back on the road or to the next build phase.
What it costs
Spot frame repair from $1,800. Full frame stretch $5K–$10K. Ground-up custom chassis $15K–$30K+.
Common questions
Sometimes yes, sometimes no. We give you an honest answer after we put it on the lift. We won't sell you a repair on a frame that should be replaced.
Yes. Frame stretch with proper splice, fishplate, and re-weld. Done correctly, it's invisible and stronger than factory at the splice.
Yes. We build to NHRA, SCCA, and custom street-legal exo specs depending on what you need.
Our structural welds meet AWS D1.1 standards. We can provide weld documentation for race tech inspection.
Spot repair: a few days. Frame stretch: 2–3 weeks. Custom chassis build: 2–6 months.
