What's in the Box

• EGR block-off plates and the applicable gasket/sealing pieces.
• Version-specific plugs or caps and hose clamps.
• Spacers and mounting fasteners.
• Installation instructions; 3-inch turbo-back exhaust only with a selected exhaust + EGR combination.

Compare the received hardware with the instructions for the selected version. Early and later EGR packages use different small parts.

Best For

• LWN-specific EGR work: Colorado and Canyon owners addressing soot recirculation, EGR-valve deposits and cooler-related maintenance in an application where the modification is permitted.
• Correct year-split selection: Buyers who have confirmed whether their truck needs the 2015–2016 or 2016.5–2022 hardware.
• Coordinated hardware planning: Owners arranging compatible calibration and choosing EGR-only hardware or a listed exhaust combination.

Benefits & Function

On the Colorado and Canyon 2.8L Duramax LWN, the block-off plates stop exhaust from returning through the EGR passages, reducing fresh soot entering the intake. Bypassing the EGR cooler also removes that cooler's exhaust-to-coolant heat transfer. The kit therefore targets EGR deposits, cooler heat load and the associated maintenance and replacement costs.

The original product information identifies improved efficiency, engine longevity and fuel-economy gains of up to 20%. These are potential outcomes rather than a result every truck will achieve; calibration, existing faults, driving and load affect the outcome. The page also identifies reduced DPF-failure risk, but EGR hardware alone does not repair a blocked DPF, resolve a DEF fault or clear an active reduced-speed condition. Exhaust replacement requires a corresponding exhaust + EGR selection.

EGR-only selection: 2015–2016 or 2016.5–2022, as labeled. For 2016 trucks, confirm the actual EGR connection arrangement and the required kit before ordering; the labels overlap within that year.

Exhaust + EGR selection: The current combination options are labeled 2016 and 2017–2019. Do not apply the EGR-only 2015–2022 range to the exhaust combinations. Confirm exhaust diameter, cab/bed configuration and hanger layout separately.

Installation Overview

For the detailed installation procedure, please refer to the installation instructions included in the package.

1. Confirm the version and truck condition. Match the selected EGR package to the truck's year and EGR connections. Diagnose existing warning lights or reduced-speed conditions before installation, and arrange compatible calibration.
2. Prepare the work area. Allow the engine and exhaust to cool. Follow the packaged instructions for electrical isolation, access and coolant handling, and compare the received parts with the version-specific list.
3. Access the EGR mounting points. Follow the supplied removal sequence for the EGR components being replaced. Protect open passages, clean the mating surfaces and retain factory parts identified for reuse.
4. Fit the block-off and connection hardware. Install the appropriate plates, gasket, spacers, fasteners and version-specific sealing pieces as directed. Confirm that connections are supported and seals are seated correctly.
5. Install the exhaust only if selected. Follow the separate exhaust instructions for a matching combination. Confirm cab/bed configuration, extension-pipe use, hanger alignment and clearance before the final tightening sequence.
6. Reassemble and inspect. Restore fluids and removed components to the vehicle specifications. Have the installer check for coolant and exhaust leaks, secure mounting and warning lights, and verify the calibration matches the completed configuration.

For available online installation documents, please see the SPELAB installation instructions library. The 2.8L DPF exhaust document covers the exhaust component; use the packaged instructions for the selected EGR version.

Emissions and Use Notice

This product alters factory emissions-related systems. Confirm applicable emissions, inspection, registration and use requirements before purchase or installation; a race or off-road label alone does not establish an exemption. Modifications may affect vehicle warranty coverage. See the EPA air enforcement information for U.S. regulatory context.

FAQ

Which trucks does this kit fit?

The stated application is 2015–2022 Chevrolet Colorado and GMC Canyon trucks with the 2.8L Duramax LWN diesel. Select the correct EGR version. The exhaust + EGR combinations have narrower year labels and require separate exhaust-fitment confirmation.

Which EGR kit should I choose for a 2016 truck?

The current options are EGR Delete(2015-2016), SKU SPOS08839SR, and EGR Delete(2016.5-2022), SKU SPOS08840SR. Because both labels cover part of 2016, compare the actual EGR connection arrangement with the product images and packaged instructions, or ask SPELAB to confirm the correct version before ordering. Do not assume the two kits are interchangeable.

What is the difference between EGR-only and the exhaust combination?

EGR-only selections supply the EGR plates, seals and related mounting and connection hardware. The 3 Inch DPF TB-Back & EGR combinations add the exhaust system. The combination options are specifically labeled for 2016 or 2017–2019; the exhaust is not included with the EGR-only kit.

What parts and materials are included?

The EGR plates are aluminum and stainless steel, with the applicable gaskets and hardware included. Images show spacers, fasteners, clamps and version-specific sealing pieces. The optional exhaust has a 3-inch inlet, 2 mm wall thickness and 409 stainless steel construction. Small parts differ between the early and later EGR kits.

Do I need a tuner, and is one included?

Yes. The product requires a compatible tuner for proper ECU calibration; these options are hardware packages and do not include a tuner. In the original customer Q&A, SPELAB stated that it did not stock a 2.8L tuner. Confirm current availability and obtain calibration specifically compatible with the LWN engine and selected hardware before installation.

My Colorado is in limp mode or showing a reduced-speed countdown. Can I install the kit to fix it?

Resolve the existing fault before installing any delete kit, as advised in the original customer Q&A. Have the truck diagnosed so DPF, DEF, sensor and calibration issues are addressed correctly. EGR plates and exhaust hardware do not automatically clear those faults or a speed countdown.

Which combination is listed for a 2018 Colorado 2.8L Duramax?

The current exhaust + EGR selection for that year is 3 Inch DPF TB-Back & EGR for 2017-2019, SKU SPES08681S3.0-OS08840SR. The original customer Q&A also calls for confirming a 3-inch exhaust fitment. Check the actual cab/bed configuration and mounting layout, and diagnose any existing faults before installation.

Will fuel economy improve by 20%?

The original product information describes potential fuel-economy gains of up to 20%. This is not a guaranteed improvement for each Colorado or Canyon. Actual results depend on engine condition, calibration, driving, load and existing EGR or aftertreatment faults.

Are installation instructions included, and can I install it myself?

Refer to the installation instructions included in the package for the selected version. The installation overview is a planning summary. Professional installation is recommended if you are unfamiliar with EGR access, sealing surfaces, coolant handling, exhaust alignment or calibration requirements. Contact SPELAB if the instructions are missing or do not match the received hardware.

Why do I need to check exhaust hangers and cab/bed configuration?

The matching exhaust manual distinguishes crew-cab long-box extension-pipe use from crew-cab short-box installation and requires adequate clearance around pipes, hoses and wiring. A customer also reported front hanger alignment concerns on a 2016 crew-cab long-box truck. Confirm the actual layout before final tightening; do not assume every wheelbase or modified suspension uses the same arrangement.

Does this replace the DPF or repair all emissions-system problems?

The EGR-only kit addresses EGR passages and related hardware. A listed exhaust combination supplies additional exhaust components, but neither selection is a universal diagnosis or repair for DPF loading, DEF faults, sensor problems, intake deposits already present or unrelated engine issues. Diagnose the truck first and match all required hardware and calibration.

What should be checked after installation?

Check the coolant level and the version-specific sealing connections, then inspect for coolant leaks, exhaust leaks, loose fasteners and exhaust clearance. Confirm the selected hardware and calibration match. Investigate warning lights or a reduced-speed message rather than assuming the hardware will clear them.
