Ford F600-F700 Truck Frame & Chassis

Frequently Asked Questions About Ford F600-F700 Truck Frame & Chassis

What years and models are compatible with your F600-F700 frame and chassis parts?

Our frame and chassis components are designed to fit Ford F600 and F700 trucks from 1980 through 2003. However, Ford made several frame changes during this period, particularly in 1989 and 1995. Always verify your specific year and VIN with our team before ordering, as frame rail dimensions and mounting points can vary between early models (1980-1988), mid-generation (1989-1994), and late models (1995-2003). We recommend having your frame measurements ready when contacting us.

What material grades and thicknesses are used in your replacement frame rails?

Our replacement frame rails are manufactured from high-strength steel that meets or exceeds OEM specifications. Standard frame rails are constructed from 50,000 PSI yield strength steel with thicknesses ranging from 1/4 inch to 5/16 inch, depending on your truck's GVWR. For severe-duty applications, we offer upgraded 80,000 PSI rails. All frame components feature a black e-coat primer finish for corrosion resistance. Heat numbers and material certifications are available upon request for commercial fleet customers.

Can I install frame repairs and crossmembers myself, or do I need special equipment?

While experienced mechanics can perform some frame repairs, most installations require professional equipment and expertise. Frame rail sections must be precisely aligned and welded following specific procedures to maintain structural integrity. You'll need heavy-duty jack stands rated for at least 20,000 pounds, a frame alignment gauge, and professional welding equipment. Many states require frame repairs to be certified by a qualified shop. We strongly recommend professional installation and can provide a list of certified installers in your area.

How do I identify which crossmember or frame bracket I need for my F600 or F700?

Crossmember identification depends on three factors: your truck's wheelbase, body type, and equipment options. Measure the distance between existing crossmember mounting holes and note any stamped part numbers on your current components. Different configurations exist for dump bodies, flatbeds, box trucks, and specialty equipment. Photos of your current setup, including mounting brackets and overall frame configuration, help ensure you receive the correct parts. Our technical team can assist with identification if you provide your VIN and application details.

What frame modifications are required when converting between different body styles?

Converting between body styles often requires significant frame modifications. Common conversions like flatbed to dump body or box truck to rollback require relocating crossmembers, adding reinforcement plates, and potentially extending or shortening the frame rails. PTO openings, spring hanger positions, and brake line routing may also need modification. Before starting any conversion, consult your state's commercial vehicle regulations, as frame modifications must meet DOT standards. We offer conversion kits for popular applications that include detailed instructions and required hardware.
