Engine & Transmission Replacements
When a big rig lays down, we don’t stand around crying about it—we pull the motor, find the problem, and build it back ready to work.
Redneck Diesel Performance specializes in complete big-rig engine replacements and heavy-duty transmission replacements for trucks that earn their keep. From full diesel engine swaps to complete semi-truck transmission installations, we handle the entire job under one roof.
Removal. Inspection. Replacement. Installation. Final testing.
No bouncing between shops and no half-finished work.
Whether you’re dealing with a blown engine, a worn-out transmission, or planning an upgrade for better reliability and performance, our experienced diesel technicians take care of the process from start to finish. We use quality components, pay attention to the details, and make sure everything is installed properly before your truck returns to the road.
Because an engine or transmission replacement isn’t the place for shortcuts. These trucks work under heavy loads and across long miles, so every connection, seal, hose, mount, and adjustment matters.
Downtime don’t make money—and a truck sitting in the shop ain’t pulling freight.
That’s why we work with urgency and purpose to get your heavy duty truck back where it belongs: on the road, hauling strong, and earning its keep.
Blown up doesn’t mean finished.
Bring it to RDP. We’ll build it back ready to work.
Out Of Frame Engine Rebuilds
When Your Engine Is Done, We Don’t Patch It—We Pull It.
When a big-rig engine is tired, worn out, or flat-out hurt, a temporary fix isn’t always enough. Sometimes the only way to repair it properly is to pull the entire engine and tear it down to the last bolt.
That’s exactly what we do at Redneck Diesel Performance.
Our out-of-frame engine rebuilds are complete diesel overhauls—not quick patches disguised as major repairs. The engine is removed from the truck, fully disassembled, thoroughly cleaned, and carefully inspected from top to bottom.
Internal components are checked for wear and damage. Worn or failed parts are replaced. Critical surfaces are measured and machined as needed. Then the engine is carefully reassembled to meet the proper specifications for dependable performance.
Pull it.
Strip it.
Inspect it.
Machine it.
Build it back right.
Going out of frame allows us to find the hidden wear, internal damage, and underlying problems that can’t be seen while the engine is still assembled. It gives our technicians the access needed to address the entire engine—not just the most obvious failure.
The result is a properly rebuilt engine ready to get back under load and earn its keep.
Not local? Ship your diesel engine to RDP. We can complete the full out-of-frame rebuild in-house and coordinate return shipping once it’s ready to go back to work.
No band-aids.
No guesswork.
No halfway rebuilds.
Just a complete big-rig engine overhaul built for the long haul.
In Frame Engine Rebuilds
Don’t Need a Full Pull? We Can Rebuild It Where It Sits.
Not every worn diesel engine needs to come completely out of the truck. When the engine’s condition makes it a good candidate, an in-frame rebuild can restore its performance without the added time and expense of full engine removal.
At Redneck Diesel Performance, we rebuild the heart of your big-rig engine while it stays mounted in the chassis. Depending on what the inspection reveals, the job may include replacing:
- Pistons
- Cylinder liners
- Rod and main bearings
- Seals
- Gaskets
- Other worn internal components
But an in-frame rebuild isn’t just about installing new parts.
Our technicians inspect the accessible components, measure critical clearances, verify tolerances, and assemble everything to the proper specifications. Every detail matters when the engine has to go back under load and earn its keep.
This isn’t a shortcut or a temporary patch. It’s an efficient heavy duty repair for engines that don’t require a complete out-of-frame overhaul.
Less teardown.
Less downtime.
More time making money.
If your big-rig engine is worn but doesn’t need a full pull, bring it to RDP. We’ll determine what it actually needs and rebuild it right.
Because parked trucks don’t pay the bills. Working trucks do.
