The kit restored compression and brought my TZR125 engine back to a smooth, strong idle. The cylinder and piston matched the original dimensions, and all the necessary small parts were included.

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.

Worked perfectly for my 2017 Jeep Grand Cherokee Summit. Hard to install in your own but it's possible. These work very well once you get them in. I suggest getting a handy friend to help you install and follow some of the online videos. Saved me at least &700 to do it on my own as I was quoted $1000 to replace at a shop
Fit looks clean as hell on my camaro 2017. The color is black Matt like. Really nice. 245/40 r20 is the tire size I decided to put on you could also put 245/45r20. The color is Matt like. I was skeptical at first but honestly it was a really good decision of a purchase. I had stock rims at 18’ and upgraded to these 20’ and honestly the driving of the car felt really good

The white light makes road markings easier to distinguish without creating a harsh blue tint. Illumination appears uniform across the lane, and the bulb remains stable over rough pavement.
The new moldings sit at an even height across all four doors and remove the faded appearance along the window line. Wind noise around the glass is noticeably lower at highway speed, and every clip remains firmly seated.
All four handles have a matching chrome tone, giving the truck a consistent appearance from every side. The pull action feels solid, and each handle returns promptly without sticking.
Fuel flow changes cleanly between the operating positions, with no stiffness at the selector. The valve seals completely when parked and stays dry around the mounting area after long rides.
Both cylinders now receive fuel evenly, making throttle transitions much more predictable on technical trails. Hot restarts happen without extended cranking, and there is no raw-fuel smell afterward.
