1967–1972 Chevy K10 4×4 Pickup Chassis
The 1967–1972 Chevrolet and GMC pickups are some of the most admired trucks ever to leave a GM assembly line, and the four-wheel-drive K10s are especially prized. Their original frames, however, carry a solid front axle on leaf springs, with the ride, steering and braking that implies.
A Frame-Werx chassis puts a 1967–1972 K10 on modern independent front suspension built around proven GM hardware, while keeping the factory body mounts and proportions intact. The body sits where it always has; only the way the truck drives changes.
Fits
- 1967–1972 Chevrolet K10 4×4 pickups
- 1967–1972 GMC 4×4 half-ton pickups
- Short box and long box
Known in the hobby as the 67–72 or Action Line pickup.
What is underneath
Independent front suspension
Geometry, steering, hubs and brakes drawn from GM’s GMT900 platform, the same hardware beneath the 2010 Cadillac Escalade, so replacement parts stay easy to find.
Multi-link rear
Locates the axle precisely, so the truck tracks straight at speed and stays composed over broken pavement or a washed-out trail.
Rated to 800 horsepower
Engineered to carry modern GM Performance engine and transmission packages without a second thought.
Two-wheel, four-wheel or all-wheel drive
Configure the drive to suit the truck: two-wheel drive, electronic-shift four-wheel drive or full-time all-wheel drive.
Hot-dip galvanized
Every finished frame is immersed in molten zinc, sealing it against rust inside every rail and crossmember.
Bolts to the factory body
Built to the original body mounting points and proportions. No cutting, no drilling.
Galvanized, not just painted
Once fabrication is finished, every Frame-Werx frame is hot-dip galvanized. The complete structure is submerged in molten zinc, which bonds to the steel inside each rail and crossmember, including the places no spray gun or brush can reach. It is the same protection trusted on bridges and highway guardrail, and it means the foundation of your build will not quietly rust away beneath a fresh coat of paint.
Prefer black? An epoxy primer and flat black finish is also available.
Spec it your way
Choose shocks from a factory-style setup through Fox, King and Rough Country Vertex reservoir coilovers; brakes from a standard aftermarket package to Frame-Werx calipers and Wilwood big-brake kits; a 3.42, 3.73 or 4.10 rear gear; and a GM Performance engine and transmission package. Buy the bare frame, the frame with parts shipped loose, or a complete rolling chassis assembled in Minnesota.

Guides for planning your build
Common questions
Will it fit my 1967–1972 pickup without modification?
Yes. It bolts to the factory body mounts, with no cutting or drilling of the cab or bed.
Short box or long box?
Both. Choose your cab and box in the builder and the frame is built to match.
Can I buy just the frame?
Yes. The chassis is available as a bare galvanized frame, as a frame with parts shipped loose, or as a complete rolling chassis assembled in our shop.
What does it cost?
A bare hot-dip galvanized frame starts at $17,900. Everything beyond that depends on the parts you choose, and the chassis builder keeps a running total as you go.
How do I order?
Spec your chassis in the builder and review the estimate. Frame-Werx chassis are sold exclusively through K5 Squared, and a deposit reserves your place in the build queue.
