If your GM truck or SUV is dealing with lifter noise, a collapsed lifter, misfires, excessive oil consumption, or camshaft damage, it may be time to eliminate the problem at its source.

GM’s Active Fuel Management (AFM) and Displacement on Demand (DOD) systems are well known for lifter failures. In addition, the frequent cylinder deactivation can contribute to increased carbon buildup on valves and in the combustion chambers, which can lead to reduced performance, rough running, and drivability issues over time.

We offer AFM/DOD delete camshaft upgrades, replacing the failure-prone components with a more reliable setup. Whether you’re repairing a failed engine or upgrading before problems start, this conversion improves long-term reliability and helps keep your engine running cleaner and stronger.

If your GM 5.3L or 6.2L engine is showing signs of AFM/DOD failure, don’t wait until the damage gets worse. Contact us to discuss your options and schedule an appointment.

This week in the shop, it’s a full house of blacked out classics.

From tracking down oil leaks and keeping that factory air conditioning blowing cold, to full engine builds, we’ve been keeping these timeless machines running strong and on the road. Nothing better than a shop packed with classics getting the care they deserve.

Just wrapped up installing a set of Stainless Works headers on a 2010 Challenger R/T

Fitment was solid, quality is top notch, and the sound difference is unreal. The HEMI breathes so much better now with a deeper, more aggressive tone.

If you’ve been thinking about headers for your Challenger, Stainless Works is definitely worth it.

This 1980 Z-28 has seen nearly every upgrade over the years, and this latest round takes it even further. We installed a Tremec TKX 5-speed, transforming the car into a true highway cruiser. With improved gear ratios and crisp, short-throw shifts, the already impressive 500hp Blueprint engine now performs on another level. We also refreshed all fluids and fine-tuned the Holley fuel injection system. Now, this car is dialed in and ready to hit the road for cruise nights and car show season.
