A Journey of Frame and Suspension Modifications on the 1974 Ford F250 Restomod:
Suspension and Frame Modifications:
**Frame Modifications:**
The restomod process began with a meticulous disassembly of the original frame, followed by comprehensive media blasting to eliminate years of wear and tear. Since the frame serves as the project’s foundation, reinforcing it was vital to meet the increased power and weight requirements of the modifications.
1. **Boxing the Frame**
The frame was boxed in sections to bolster its structural integrity. This method involves welding steel plates to the inside of the frame rails, significantly increasing rigidity and reducing flex under heavy loads.
2. **Custom Motor Mounts**
A distinctive feature of this restomod is its powerful diesel engine. Custom motor mounts from Diesel Conversions NW were integrated flawlessly, ensuring a stable base for the robust diesel engine.
3. **Strengthening for Heavy-Duty Components**
The cross rails were carefully modified and reinforced to house the potent diesel engine, the robust NV 4500 transmission, and transfer case. This upgrade ensures the frame can endure the substantial torque produced by the drivetrain.
4. **Front Frame Reinforcement**
The frame’s front end was fortified to accommodate the Smittybilt 120 cable winch, guaranteeing a secure anchor for challenging off-road recoveries.
5. **Towing**
The frame was enhanced to support a gooseneck hitch, compatible with a fifth-wheel hitch adapter. The rear receiver hitch was upgraded to a class IV equivalent, amplifying the F250’s towing versatility.
6. **Epoxy Priming and Chassis Paint**
After the rigorous modifications, the frame received protective epoxy priming and a coat of chassis black paint, ensuring longevity and visual appeal.
**Suspension Modifications:**
Revamping the suspension to modern standards was pivotal for this restomod, offering the vintage truck a refined yet resilient ride.
1. **Multi-Link Coilover Front Suspension**
The original leaf spring front suspension was replaced with a sophisticated multi-link coilover system, custom-forged by XO Fabrication. This upgrade markedly elevates the truck’s handling and ride comfort across different terrains.
2. **Upgraded Front Axle**
The front axle was swapped for a disk brake Dana 60, delivering enhanced stopping prowess and resilience. It was further augmented with Yukon 3.08 gears and Yukon hubs, boosting its performance and dependability. The axle received an epoxy primer and medium gray paint.
3. **ARB Locker**
An ARB locker was incorporated into the front axle, promoting improved traction and control in challenging terrains.
4. **Rear Springs**
The original rear springs were replaced with a Skyjacker progressive spring pack, ensuring a more fluid ride. The rear suspension was enhanced with Firestone airbags and an Airlift spacer, allowing the F250 to carry heavier payloads effortlessly.
5. **Upgraded Rear Axle**
The rear axle was substituted with a Ford Sterling axle and upgraded to disk brakes, further improving stopping capabilities and durability. This axle was also treated with an epoxy primer and medium gray paint.
6. **Torque Bar Addition**
A torque bar was strategically added to the rear axle to counteract axle wrap, alleviating the stress induced by the engine’s immense torque.
7. **Power Steering Conversion**
For a more responsive driving experience, the hybrid steering system was converted to power steering.
