We are here at UCC introducing to the industry a couple new billet products, supporting a truck we sponsored and competing in ODSS 6.70 & Outlaw Unlimited No Time classes.

What an absolute honor to have our products displayed at the Exergy Performance and Dirty Ho**er Diesel / DHD booths and to be small part of Morey’s UCC truck!

More product info coming soon!

2004 5.9 Cummins came in with a rough hazy idle and lack of power. We determined this rig needed a fresh set of injectors. Exergy Performance Sportsmans were installed to save the day. A Fleece Performance Engineering Cheetah Turbo, BD Performance Manifold, S&B Filters Intake and a HPT UDT Tow Tune were added as well to tie it all in together. This truck runs like a top, makes more efficient power, and is ready to tackle any job! Thanks JR for trusting DP Customs!


Wishing all of you a Happy New Year! Thank you for supporting DP Customs in 2023, this past year has been one for the books! We look forward to sharing some cool new DPC products, exciting shop announcements, and fresh media content in 2024!

Thank you for trusting us with all of your automotive diesel truck needs!

Seger’s LB7 came in for a DPC 750hp Street Trans after his last “built” trans recently done by another shop was already flaring, slipping and limping. It was also incorrectly stalled for the turbo size he currently has. Our units come with a Mishimoto Automotive cooler and he opted to have a Dirty Ho**er Diesel / DHD Dirty Alli Locker installed as well. After data logging the new set up, we added a S&S Diesel Motorsport 10mm pump to help maintain fuel pressure with the larger injectors it has and dialed it in with UDT DSP5. What a blast to drive and great overall set up. Thanks for trusting DP Customs!


Wishing all of you a very Merry Christmas!

Morimoto Lighting XB Headlights/Foglights installed on this clean Duramax. These DOT LEGAL LED headlights/foglights light up the dark roads at night better than factory, look mean, and offer a nice DRL as well. Thanks for trusting us Lenny!


After working my truck hard for 170000 miles. My head gaskets unfortunately let go. Daman and I got a plan of attack figured out and parts ordered. Once all the parts came in I dropped my truck off on a Sunday afternoon and got it back Thursday night. He worked long hours and busted his butt, even on his son’s birthday to get my truck back on the road! DP Customs is the shop to go to for any diesel truck needs in the area!!!

L5P came limping in with multiple codes and a plugged DPF. After a NOX Sensor & Turbo Actuator replacement she’s good to go! Force regen to clean it out and she’s back on the road!

2024 GMC Denali Ultimate 2500HD Duramax right off the dealer lot came to see us for a Cognito Motorsports 3” Leveling Kit and Tie Rods. This kit properly maintains ride quality and ball joint angle and gives the driver a comfortable ride with Fox 2.0 shocks. Thanks for trusting DP Customs with your brand new truck!

Another Allison in for a complete rebuild. This one suffered from a torque converter failure and had some smoked clutch packs which led it to see extremely high fluid temps. We got it all fixed up with many new internals transforming it into our Street Trans along with a new CSF Radiator, and a Mishimoto Automotive Trans Cooler.

When our customer came to us with his 2006 F750 with a vision to modify it, we knew right off the bat it would be a team effort. With the help of these great company’s in Fort Dodge we were able to create this head turning truck! Truly one of a kind!

DPC Competition Allison. We know what it takes to build something that can withstand abuse on the dirt, strip and street. Reach out to us today to get a quote on a proven transmission!


DPC Shop Truck
1st Place in Open Diesel

Something that makes me tickled to achieve at the hometown pull. We have more power on tap for the open class but I’m happy with what it currently does keeping the motor together and having a STREET truck that can be drag raced or daily driven the next day. The DPC pedestal and gate tube once again doing its job reaching 2000+* without issues. I think we are finally seeing this truck come around getting dialed in for the year!


Fort Dodge Iowa Hometown Party!

Comment what your pulling!


We wish you all a safe and fun 4th Of July! God Bless America!

This 6.7 Cummins came in with what was thought to be transmission issues. After we mechanically and electronically diagnosed it we determined that the vanes were stuck with a shot actuator. Without the vanes properly working, expect to have laggy take offs and worst mileage. A Fleece Cheetah was installed to get her back on the road. These chargers have been proven over time, offer a great warranty, and will make/support more power. Thanks for trusting DP Customs!


We’ve headed out to attend Ultimate Callout Challenge. DP Customs shop truck will be competing in 6.70 ODSS as well as a couple dyno classes.

We will be closed Thursday June 1st & Friday June 2nd & back open Monday June 5th. Thank you!


DP Customs has a motto of taking pride in work performed and being upfront and honest. This means taking the time to do a job right, the first time. It means staying in communication with the customer and explaining further steps in troubleshooting or repairing your vehicle. We use quality parts and “upgrade” your truck components better than factory when possible. When doing performance work, we use years of gathered knowledge and hands on experience to give you the leading edge against competition and give you the satisfaction you deserve.

In order to maintain the same great reputation which means giving every truck the attention it deserves, we have decided to move to appointment only with no walk ins. This will give us more time to dedicate to YOUR vehicle without other outside distractions. With an influx of work, limited staff and small shop space we are booking out 4-6 weeks for major repairs. We hope to find solutions in the near future to better assist the community cutting down lead times.

For truck related questions, scheduling, or appointment inquiry’s please contact 515 408-9477 during normal business hours Monday-Friday 8am-5pm. If it is outside of these hours or if nobody answers, please leave a voicemail or text message and we will get back to you as soon as possible.

Thank you for your patience and understanding!

DP Customs T4 Billet Wastegate Pedestal 04/21/2023

‼️ Introducing the WORLDS FIRST Duramax Billet T4 Wastegate Provisioned Pedestal by DP Customs. ‼️

After months of engineering, we came up with a pedestal that covered every problem seen with competitors. No more cracking, no more clearance issues and easy wastegate plumbing to name a few! Your 44/45mm wastegate will clear the fuel rail and fuel rail sensor (if applicable) and put the discharge opening in a perfect spot for dumping into the atmosphere through the hood or into your exhaust through the downpipe. If you do not run a wastegate, simply cap the provision off (caps sold separately) and enjoy a QUALITY billet T4 pedestal. With an easily removable base, this pedestal can also be adapted to use on L5P Duramax blocks (L5P base sold seperate).



* 5 axis billet machined

* removable and adaptable base for fitment and use with the L5P Duramax block (sold separately)

* 6.75” height for use with most all standard 01-16 Duramax S400 kits

* 1/2” thick bolt mounting base

* 3/16 thick exhaust channel walls preventing cracking and keeping thermal insulation

* 44/45mm wastegate provision fl**ge

* 3/4” thick top T4 fl**ge to withstand heat and prevent warpage

* -12AN turbo oil drain clearance

* standard m10x1.5 thread

* true flowing channel design with no obstructions for turbulence or bottle necking

* LB7-L5P intake runner clearance/fitment
