Great price for someone looking for a coil upgrade to your trail bike (* trail bike being the segment name for mid travel mountain bikes, circa 120 – 150mm rear travel).
MTB shocks are sized with two numbers, the total eye to eye length and the stroke length. This is for the 210mm (eye to eye) x 55mm (stroke). Other sizes are available but prices vary. Generally each bike can only use a specific size. Make sure you get the correct size for your bike. Also, the coil spring is sold separately as they are in different weights to suit different ride weights and suspension layouts.
This is directly from Fox Australia and my understanding is they are very good with warranty.
Note: Springs are not included with coil shock.
