Unbelievable power boost for my 300! Easy install with clear instructions. Runs stronger than ever now.
Quick delivery, good item.
Got this cylinder kit (with piston and top end gaskets) for my 300 SX/XC—just a standard one, not big bore. But man, it’s held up amazing even through all the rough use I’ve put it through! No issues so far, works like a charm. Super happy with how durable it is.
Quick and efficient delivery! The package was sturdy and the contents were well protected. The kit appears complete with all necessary parts. A hassle free experience overall.
I received the item, it was packaged well and was as described. There was only one issue,the hole where the cam tension rod goes was just a bit to small. I tried installing with 2 different lubes, wiggled and twisted as much as it would allow and still couldn't get it to pass through the cylinder. I tried the old tension rod thinking it could have been the new rod. It wouldn't pass through either. Rather than return the item and wait for a new one with possibly the same issue, I decided to drill it out one size larger. I would highly recommend not doing this unless you have a drill press and feel comfortable using it. After drilling and cleaning it very well, the rod passed through, was installed and all is well.

Fits nice, easy to install. Looks great. No complaints.
grill looks amazing shipping was super fast, and seller is super friendly, second time ordering from them.

This AFM disabler improved my truck’s throttle response noticeably. Easy plug-and-play install, though a guide for the indicator lights would help. Overall, it works great and makes driving smoother.
This MIL eliminator cleared my Mustang’s check engine light right away. Simple plug-and-play, and it’s been working perfectly. A smart fix for exhaust codes.
This carburetor made my KX450F start and run smoother instantly. Simple to install, and the throttle response is crisp now. A reliable OEM-style upgrade.
