Stihl Ms171 Replacement Piston 37mm, Replaces Part # 1139 030 2003, Note This Kit Is Not Made In China. This Is A Very High Quality Replacement Cylinder Piston Kit. Material- The factories use the highest grade material coming from Japan. This is AC4B. 2. Coating- Before coating, all performance saw cylinders are put through 13 preliminary processes to ensure maximum penetration, thickness and coverage. Coating thickness is .04-.06 mm of chrome which increases the life of the cylinder. 3. Machining- Complete machining on all cylinders is performed by accurate CNC tool machines. 4. Die-Casting- All cylinders are made by slow gravity fed die-casting. This increases the weight of the cylinder which enhances the performance and life of the rebuild. 5. Tooling- Each cylinder tooling has limited life and are replaced after the manufacturing of 50,000 pieces. All tooling is checked on a monthly basis. 6. Quality Control- Special inspection is done on every cylinder inlet and exhaust port which includes chamfering of all burrs. Every 20th cylinder that comes off of the production line in thoroughly inspected for accurate tolerances. cylinders & pistons are manufactured by factories that have over 30 years of experience in the cylinder & piston industry. They provide OEM chainsaw suppliers (Western, European, & Chinese) as well as OEM for motorcycle companies. You can expect three times more life out of our cylinders & pistons than our cheaper competitors. Most of the cheap Chinese cylinders that we see look good, fit okay, but do not last because they don't go the extra length to ensure good quality. Note: We recommend when rebuilding 2-cycle equipment that you use a piston ring compressor kit to ensure professional results.

Online vs Instore
Size: 40, Color: #01khaki
As to be expected, not seeing and touching before purchase. I bought three pairs of these shorts in different colors for a trip to see my son graduate from his Army National guard AIT. I would rate the overall a five based on fit, quality, and comfort. One thing that I have to mark down, is they have elastic waist bands as described! In the description pic's, they are shown with nice long tie strings. The reality of what I received is the stings are too short to tie. They were almost the same circumference as the waist band, so only able to tie in a small knot, rather than a bow. no Biggy, until it's time for the restroom. Hopefully it's self explanitory....fumbling around with a knot! waist fits as stated to my size, but add weight of wallet and cell phone, and after a few steps, they begin to slide down. Tie string a must. I will see about finding something longer, as I do like them overall!

I love them but pockets tear easily
Size: 34, Color: #01black
I love them. They look nice and they are comfortable. I bought a total of three and they're all I wear in the summer. Unfortunately the strap pockets wear out easily. On my left pocket I store a ridge wallet and my keys. For two of my most worn pair, the strap tore up to where it no longer holds the pocket closed properly. On one of those in the same pocket, a hole ended up torn in the corner. The third one I had to throw out after it shrunk after being washed improperly (can't wash them like I did my previous shorts which I washed the same way as the rest of my clothes). I think I'll continue to wear them, maybe even buy one more, until I find something better.
