Comments about Pedal Return Spring:
The spring was a perfect replacement. Doing the repairs ourselves saved a fortune. The only difficult part of the work was removing and then reinstalling the master link on the chain. Advice on how to best do this would be appreciated.
Comments about Pedal Return Spring:
This spring arrived quickly and was of good quality and fairly priced. It was easy to install and I found the videos by shopsmith to be very helpful. I'm up and running again and have several hours already on the machine.
Comments about Pedal Return Spring:
WOW!!! Found the part to my 12 year old rusty, sweat encrusted Stairmaster 4000 PT with a broken pedal return spring very quickly on your on-line catalogue. I thought I was looking at chucking the old device and spending $2000 for a new one or a $300 in home service charge. Instead I bought 2 springs from you, got them in 2 days and am now stepping again for [$] on a machine that feels as good as new again. Does it get any better? Absolulely not.

Needed to replace broken spring on stair master, this spring is an exact replacement, and I am happy that the stair master is back working after only a few minutes of work. Good price for part, prompt shipping
