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.

This soap is a second line defense against itching due to allergies.
This is only the second thing my husband has asked me to reorder from Amazon. He was itching all the time, so I ordered this for him. It stopped the itching because when he ran out and started itching again, he told me to reorder it immediately. I use an allergen free detergent for washing our clothes because we both tend to have allergy problems. This is a second line of defense against itching from allergies since soaps and detergents tend to trigger ours. It would also be nice to cleanse your skin after coming into contact with poison ivy or oak. What I paid is worth it to me because the value is in not hearing him complain! There’s no unpleasant odor and it’s a good quality soap. I can’t speak to the moisturizing part because he doesn’t care about things like that, but his skin must be moisturized or he’d be itching again, lol. I’ll definitely keep buying it.
