    • Nice upgrade from failed stock one
Size: 165mm
Review Image by CDK
Got 165mm for Freesky Swift Horse (Freesky parts page has this shock listed). I had to tap the factory metal bushing out of the main body so i could transfer the Freesky's in, the shock end metal and plastic bushings fit front bike bracket just fine. BIG improvement on ride! Has blue oring on shock to act as a memory marker of total compression, you can fine tune it from there. ... show more

    • Should’ve gotten it sooner

Let me say this: this shock works. It does what a shocks supposed to do. It’s not a gimmick like others. If you’re on the fence about getting this shock, just get it. Stop wasting money buying the cheap spring shocks that fail after a few ride. This shock works. It makes the ride so much more comfortable and smooth. No more bottoming out from spring shocks. Open it up and ride off road or across afield of grass like you’re on pavement. It’s that effective. The adjustments are spot on. Easily accessible to adjust on the fly. Bought this for my razor mx650 and it’s an exact match. Just drop in and go. Should’ve gotten this a long time ago instead of wasting time and much going cheap with all the spring and “air” shocks out there that did nothing but raised the ride height, fails and eventually just bottoms out. ... show more

    • Looks good - will update after riding
Size: 190mm
Purchased this shock to replace a 20 year old Fox Float RPL. At first glance this is a great replacement/upgrade. Will update once I get a chance to ride it. Update: First riding impressions are great. Very smooth action. I used the suggested settings for upper and lower pressure. Damping works well and can be dialed in easily. I was never a fan of the 'pro-pedal' semi-lockout mode of the Fox shock. This DNM shock has a better 'middle-lockout' mode. Note that the mount hole sizes in this shock were 14mm, whereas the original shock had 15mm holes. The bushings in this shock are 14x12 and in my Fox shock they were 15x1/2". I was able to use a small lathe to modify a combination of the the existing spacers and included spacers to make it work, but tbh I was expecting drop-in replacement compatibility. Maybe shock standards have changes over the years. My Fox Float RPL was a 2006 model. ... show more

    • Great shock after leaking valve fix
Size: 165mm
Great shock. Second one I own. One on a Mountainbike. This one for a Tuttio Adria with minor modification to battery case. However, this one had a leaking shrader valve on the main air chamber. Not a slow leak, just air rushing out after pumping it up. Ordered a $6 kit to replace the valve. If I was not handy or familiar with tools, this would have been sent back. ... show more

    • Great Air Shock!
Size: 165mm
This is a quality Air Shock. Put it on my E-Bike. Holding air nicely so far. I like the adjustments on it. It is doing a nice job making my ride a little more pleasant. I replaced an air shock that had to refill about every 3-4 days.

    • best budget shock for the rear
Size: 190mm
got this for a replacement rear shock on my ozark trial soliom fs2 ,, i got the 190mm one and its a perfect fit.. the ride difference is night and day , jumping is so nice and has soo much room for error because ethe rear shock soaks up the bumps and mistakes and keeps you moving forward as apposed to bucking you over the bars. you will need to buy a shock pump to adjust the settings, ($10 -30) ... show more

Fit perfectly on my Ozark Trail FS.2 Slalom! So installed super easy. All you need to do is swap out the top inner bushing (silver rod) and use the old spacers and rod. The bottom bushing is the same. Rides like a completely different bike and makes me want to upgrade the fork even more now! Absolutely great budget friendly shock. ... show more
