Every now and again someone needs a shock length that isn’t readily available. Here’s how I made a 9×3 shock out of a stock 8.5×2.5.
A customer came to me with a tall order. He owned the most basic adult tricycle you could possibly get. Keep in mind that stock, these trikes are driven only by one of the rear wheels (the other wheel just spins freely) and are stopped by a stupid band brake that ONLY works on the driven wheel.
