  1. Worth the wait 5 Star Review

    Posted by on 28th Mar 2017

    After being back order for longer than i wanted they came available and I ordered four. Once ordered communication from aircraft specialties were great. They were shipped promptly. The cylinders are of excellent quality. It was worth the wait to have brand new cylinders for my rebuilt.

  2. Best security for the money 5 Star Review

    Posted by on 28th Aug 2015

    New is the way to go! Perfect fit with all of the gaskets and seals in the kit. For just a little more than an overhaul price, it is reasuring to have a brand new cylinder, piston, rings, etc. that worked perfect the first time. I spent a little more and got all new intake seals, nuts and bolts for that half of the engine to get rid of pesky seeping of fluids. Will go this route again next time.
