WHAT OUR CUSTOMERS SAY
“Truck had the classic lifter tick at startup and was throwing misfire codes on cylinders 4 and 6. Dealership quoted me $6,800. These guys did the full cam and lifter replacement with AFM delete for significantly less — and the truck runs better than it ever did. Zero tick, no codes, no issues. Couldn't be happier.”
Marcus T.
2019 Chevrolet Silverado 1500 5.3L
“I was getting a P0300 random misfire and some oil consumption I couldn't explain. Took it to two shops before finding these guys. They ran a full diagnostic with GM-specific tools, identified a collapsed AFM lifter on cylinder 7, and gave me a clear written report with repair options. Honest, thorough, and no upselling.”
Derek W.
2021 GMC Sierra 1500 6.2L
“My Tahoe started ticking about 60k miles in. I knew about the AFM lifter issue from forums but didn't know who to trust with the repair. A friend referred me here and I'm glad he did. They explained everything, showed me the worn cam lobe, and had it back to me in two days. Runs perfectly. These guys know this engine inside and out.”
James R.
2020 Chevrolet Tahoe 5.3L
“My Yukon had a catastrophic lifter failure that took out the cam. Engine was toast. They sourced a remanufactured engine, did the AFM delete during install, and had me back on the road in under a week. The whole process was transparent — they sent photos and kept me updated throughout. Exceptional work.”
Anthony L.
2018 GMC Yukon XL 5.3L
“Caught the lifter issue early thanks to these guys. Brought it in for a noise I couldn't quite describe — they identified early-stage lifter wear before it caused cam damage. Saved me from a much bigger repair down the road. Fast turnaround, fair price, and they actually explained what was happening in plain English.”
Brian K.
2022 Chevrolet Silverado 1500 5.3L
“Dealership wanted $9,000 and a three-week wait. Got it done here for a fraction of that, faster, and with better communication throughout. The tech walked me through exactly what failed and why, and explained how the AFM delete prevents it from happening again. My Escalade is back to running flawlessly.”
