How much does it cost to convert truck to 4x4?

Converting a two-wheel-drive truck to four-wheel drive typically costs roughly between $4,000 and $15,000, depending on the model, parts chosen, and whether you do the work yourself or hire a shop. In some cases the total can be higher, especially with modern vehicles that require complex electronics integration, or lower if you source reliable donor parts and perform the work yourself.

Nowadays, buyers and DIY enthusiasts weigh the appeal of a 4x4 conversion against the availability of affordable 4x4 trucks on the market. This article lays out the typical price ranges, the main cost drivers, and practical routes you can take to achieve a 4x4 drivetrain, with considerations that apply across pickups and SUVs.

Costs and options

Several broad routes exist for a 2WD-to-4x4 conversion, each with its own cost profile and level of complexity.

• DIY conversion using donor parts: If you source a used front axle, transfer case, driveshaft, and related hardware, you can keep part costs in the low-to-mid thousands. Expect to spend roughly $2,000–$6,000 on parts, plus a substantial investment of time, tools, and mechanical know-how.


• Kit-based conversion installed by a shop: For some makes and models there are bolt-in or retrofit kits that simplify the process, with labor bringing the total to about $4,000–$12,000 depending on parts quality and vehicle. Parts may cost $2,000–$6,000, with labor often representing the larger share of the bill.


• Full professional conversion on a modern truck: For newer vehicles with complex electronics (ABS, traction control, stability programs, and telematics), professional work can run from $12,000 up to $25,000 or more, particularly if substantial wiring, calibration, and body/frame modifications are needed.


• Alternative path: buying a used or certified pre-owned 4x4 instead of converting: Depending on the model and mileage, a ready-made 4x4 can range from roughly $8,000 to well over $40,000, sometimes offering better value and warranty protection than a one-off conversion.

Concluding from these options, the right choice depends on your budget, the truck model, and how you plan to use the vehicle. In many cases, a used 4x4 donor vehicle or a factory-new model might be a more predictable route than a bespoke conversion.

What affects the price

Several variables drive the final bill for a 2WD-to-4x4 conversion, from vehicle-specific complexity to the quality of parts used.

• Vehicle model and year: Some trucks were never designed with easy 4x4 retrofit options, while others have well-documented kit compatibility. Modern trucks with advanced electronics often require more extensive wiring and computer work.


• Parts quality and source: Rebuilt or remanufactured components can save money, but new factory parts cost more and may offer longer life and better reliability. Donor-part availability also affects price.


• Labor rate and shop expertise: Rates vary by region and by whether you use a specialty shop or a general mechanic. Labor-intensive or custom tasks raise the bill.


• Electrical and calibration work: Modern trucks require careful integration of ABS, traction control, speed sensors, and instrumentation. That work can be a significant portion of the cost.


• Auxiliary upgrades: Steering, braking, suspension, and fuel-system modifications may be required to handle the front drivetrain, affecting the total.


• Geographic and logistical factors: Shipping parts, obtaining core exchanges, and local availability of skilled technicians can push costs up or down.

Understanding these factors helps owners set realistic expectations and avoid surprise costs once the project starts.

Planning and decision factors

Before committing to a conversion, consider your goals (daily driver vs. occasional off-roader), how long you can tolerate downtime, and whether a factory 4x4 or a donor-based conversion better suits your needs and budget.

Summary

Converting a 2WD truck to 4x4 is a substantial undertaking with a wide cost spectrum. For those on a tighter budget, DIY sourcing used parts can keep costs in the low thousands, but time and technical skill are essential. For many buyers, a professionally installed kit or opting for a ready-made 4x4 vehicle offers more reliability and predictable performance, often with higher upfront costs but better long-term value. No matter the route, careful planning, model-specific research, and reputable parts and labor are key to a successful conversion.

How much extra does 4 wheel drive cost?

Cons of AWD/4WD
Added cost: The cost of an AWD or 4WD system can range from $1,500 on a Honda CR-V to about $5,000 on a Ford F-150. You'll also have to factor in slightly more for gas because the vehicle's rated fuel economy will be lower.

Can you change a truck from 2WD to 4WD?

Yes, you can change a truck from 2WD to 4WD, but it is a major, complex, and expensive project that involves replacing nearly the entire front and drivetrain. The conversion is only recommended if you have a specific reason, like converting a classic truck, and it's often more practical to sell the 2WD truck and buy a 4WD version instead. 
What a 2WD to 4WD conversion involves

• Donor vehicle: It is easiest to use parts from a donor truck of the same make and model and year range to ensure compatibility. 
• Major parts replacement: You will need to swap out a large number of components, including the transmission, transfer case, front axle, front driveshaft, rear driveshaft (and potentially shorten the existing one), front suspension components, steering components, and associated wiring and linkages. 
• Frame modification: In some cases, you may need to modify the frame to accommodate the new components. For example, you may need to change cab mounts to correctly mount the new front suspension. 
• Cost: The cost can be very high, easily exceeding the value of the truck, especially if you are paying for labor. 

Why it's often not recommended

• Complexity: The conversion is intricate and requires specialized knowledge and skills to complete correctly. 
• Cost: The cost of parts and professional labor can easily be more expensive than buying a comparable 4WD truck outright. 
• Difficulty: It can be difficult to find all the necessary, compatible parts, which can lead to reliability issues. 
• Resale value: The truck's title may remain 2WD, and the value of a modified vehicle can be lower than a factory-built one.

What do I need for a 4x4 conversion?

You'll need 2 drive shafts, trans and t case, front axles, shifter console, front diff and 4wd harness. And stuff. I'm +90% done with my 99 4Runner limited 4x4 swap. You need: front diff, CV Axles, driveshafts, 4x4 hub with knuckle L & R, 4WD Transmission, & J Shift Transfer case.

How much is it to convert a truck to 4WD?

They do 4WD conversions on full size vans using all OEM parts. Their conversions are roughly $12,000. You could probably do it cheaper, but, I think they use all new parts. The truck in your flare, the 04 Silverado 1500 2WD, most likely has a coil spring front end.
