DD15 Rebuild Cost – Inframe & Long Block [DIY & Certified Install]

If you have a Freightliner or other truck that needs to be replaced, you might be very concerned about what this service will cost. Engine services as a whole are expensive for large vehicles and there are many considerations related to labor and location that might impact your overall costs for the service.

Many people do not have the skill or the tools to take care of this job themselves, so labor will almost always be one of the primary costs that are associated with this service, as well as travel to the location where the service will be performed.

When looking at the cost to rebuild a dd15 engine you have two options, an inframe rebuild and long block.

The average cost for a DD15 inframe is $6,000-$8,000. On the other hand, a long block DD15 rebuild cost can be as much as $20,000. Labor can impact the total cost of this service greatly and labor is often about half of the cost of the service or more.

If you know that you need to pay for this kind of service and are hoping that you can keep things to the lower end of the cost average, you may have to look around at various repair locations to try and find a better deal.

What Do the Actual Parts for the DD15 Inframe Cost?

This is the biggest question that many people have, and if you want to take care of this service yourself and save a lot of money on the labor you can do that. You will find that this might be an involved process, and most people say that it takes them a minimum of 3-4 days.

This might impact your ability to work, so you will need to consider this part of the repair process as an added cost if so. The cost of the actual parts can vary depending on your location and the shipping that you will have to pay to get the parts to you.

The average cost for the parts will be $2,500-$4,000. Some kits will come with all of the unique parts that you need and others will require that you track down seals, rings, and other pieces of the assembly.

You can often find these kinds of complete kits on eBay, for example. The prices can range quite a bit from vendors like this and you could get a very good deal if you are tracking the price ranges over the course of a few weeks or so.

You should be sure that you are looking at new kits only since these kinds of sellers will not vouch for the condition of these kinds of items without you doing your own legwork. Some sellers will offer you free shipping, and you should consider this a major part of your consideration when looking to buy something like this for your own repairs.

Without free shipping, you can expect anywhere from $400-$600 in shipping to be added to the cost of your purchase.

How Much Does Labor for DD15 Inframe Services Cost?

The labor is the largest part of your cost for this kind of service in most cases. You might find that labor will vary per your location. Some regions of the US have much higher costs for mechanic services of all kinds.

The average costs for labor can vary as well if you are working with a dealership or a private mechanic. Most places will charge you for about 40 hours of labor for this repair at an average of $100. This means that you will come out with about $4,000 for the service.

There might also be warranty costs associated with your new engine parts. These can vary a lot and might be around $500-$1,000. Some parts of the US report labor at $75 an hour, but the 40 hours of standard labor are pretty uniform.

This means that in Texas and other states that offer the lower labor fee, you will be out about $3,000 for the labor for your service. You might need to add 10 hours or so of labor if you want additional services done to the oil cooler, compressor, engine harness, and other engine parts that are associated with this service.

This can add up quickly, as you can see, which is why so many people are motivated to do the repairs themselves if they can do the actual work.

How Much Do Various Unique Parts Cost?

If you do not use a kit for your service, you might have to buy the parts that you want piecemeal. The pistons, rings, bearings, and liners are going to cost around $3,300. The head would be another $1,800 on average.

As a comparison for costs, the kits that you can buy come with cylinder kits with liners, pistons, and a ring set as well as rod bearings, upper head gasket set, oil pan gasket, rod bolts, main bolts, piston cooling nozzles, injector o-ring kits and more for $3,795-$4,300.

This makes it pretty clear that the parts bought individually are much more costly than investing in a kit.

Cost for a DD15 Inframe

The costs for this kind of service can vary greatly across the US, as we have discussed earlier in this article. You will find that these are the average costs that you can expect with labor in your area.

 Some shops will use aftermarket parts or the kits that you have ordered and just charge you the labor. This can save you a lot of money in some cases as well. Calling around to find out the labor costs for shops in your area can help you to rule out places that will not do this service in this manner.

You can also rule out shops that charge high labor costs in this way as well. You might find that you can get the kit for as little as $2,000 or so and then only have to pay for the labor.

If your shop charges on the low end of the normal labor, this could save you a lot of money. This is not going to be an option at dealerships, but you might find that independent shops will sign off on this process.

This could also impact any warranty that comes with the new parts, so you should look into this consideration carefully before committing to having the service done in this way. There is no sense in saving money on the service, only to be unable to use the warranty when and if you need it.

Invalidating a warranty is like committing to spending thousands more on potential repairs that should have been covered by the warranty.

Other Issues That You Might Have to Pay for Related to This Engine Service

If your engine has been suffering from leaks or other hard-to-diagnose issues, you might have to pay for diagnostic services. These can cost about $50-$60 an hour at most shops.

This might only take a couple of hours, but then you could also find out that there are additional repairs that will need to be completed before your service is complete.

Chasing after electrical gremlins can also add up. Diagnostics for this kind of problem can be as much as $75 an hour and repairs will be expensive in some cases. Electrical fixes can add another $1,500-$2,500 to your DD15 inframe costs.

Always make sure that you are prepared mentally for additional costs to be added to your overall service. This can make the real total a pleasant surprise when all is said and done.

If you are prepared for the worst, then you will at least have the right amount of money set aside for worst-case scenario services. Being prepared for a few extra thousand dollars if surprise costs is always a good rule of thumb when dealing with this kind of service.

DD15 Inframe Costs Can be High

This is one of the kinds of services that often runs into the many thousands of dollars. If you are able to do the service yourself, you might be able to save a lot of money, but you will have to invest the time into the repair.

Time away from work is part of your total cost when you are completing this service yourself, and should be looked at as part of the total charges for the service that are built into your labor costs.

Being able to keep working using another truck or at least knowing that you will get back on the road again and back to work in a timely manner can make the labor cost for this service well worth it.

There are many ways to look at expensive services like this one, and you should consider all of the various pros and cons of the ways that you can get this service done when you are deciding if you want to pay for labor or not.
