DNM Damping 3 System Mountain Bike Air Rear Shock Rebound/Lock Out/Air Pressure Adjustable AL 7005 Shark/AL 6061 Shock Body

Replaced stock shock absorber on my Freesky Alaska ebike. Although the shock is slightly longer than the original (165mm vs. 150mm), there was no noticeable difference in frame geometry and a very slight difference in height. Lowering the seat less than an inch fixed that. The shock itself is a tremendous upgrade and provides a plush ride even at my weight (~225lbs). Make sure to order M8 Aluminum spacers in various lengths and a set of M8 stainless flat washers in .5mm thickness to use as shims. You will need a combination of these to get the correct centering fit on the upper shock mount. If I recall, I used (1) 20mm long spacer and (3) .5mm washers on each side of the shock for my Alaska. After that, the installation takes minutes.

Easy 5 minute swap from old stock shock to the DNM one. Lightweight and has performed exceptionally. It came with extra bushings as well which I didn’t need but is nice to have.

I have this on a modified MX650 and it does the job. I’m 190lbs with the 200mm shock and no matter how much air I put in upto 175 psi, it has around 35% sag. Lockout is nice when on the road but I like to hit the trails hard and could use the rear a bit stiffer to stop from bottoming out. Regardless, for the price, it’s a good value.

Excellent shock for the money. I watched a bunch of reviews on this shock and the reviews didn’t lie completely impressed. Get yourself one you will be happy!

Had an old giant anthem with a bad rear shock that was not repairable. After seeing the cost of a new Fox shock I realized that option wouldn’t work. For the price this shock was worth a try and the specs matched….at least most of them. To get this shock to work with my existing bushings from the giant I had to ream out the eye holes on both ends to 15mm. Additionally the eyelets on the new shock were wider so I had to grind down the old bushings so it all would fit. But, after a few hours of work it was installed, pumped to specs and worked impressively well. Now I’m just not sure of the longevity.

Had my ebike about a week before I found out what riding on a cloud was. The factory pos rear shock sucked and the front springer fork felt smooth.Added the DNM air shock and got a shock pump. Began to play with different pressures and damping speeds. Watched some videos and finally figured it out after a few weeks. 1st. Get a decent (dnm makes one but wasn't in stock at the time)) Shock pump that can be removed from the valve without loss of air. 2nd. Learn how the positive and negative chambers work or just use a chart to fill them. 3rd. You want some sag (20%ish sag) allows the shock to eat up those smaller bumps by keeping rear tire trailing the ground or small obstacle while your weight load lightens as you crest a bump.4th. The red spinning thing next to the red lockout switch.. that's your damping adjustment which speeds up or slows down the rate of compression or rebound. Go all the way one way and roll slowly off a bump then the other way. Do it going fast too.Bounce on the bike and feel the speed at which you rebound after compressing.Too fast and you'll prob go over a bump and be slapped in the ass by the seat. If to slow and your going over bumps quickly the suspension won't have time to return before it's needed to compress again... Your damping adjust (red spinning thing) with one finger can be spun from end to end with about 10 spins (as far as your finger can spin without resetting on the dial) I keep mine about 4 spins away from slow.Anyways, it's a great shock. Holds air near perfectly. No oil leaking. Just a happy shock.Just ordered air forks so I'll be plush all the way around.

I needed to replace the rear shock on my 2013 Salsa Spearfish and found the DNM when searching Amazon for one of the $300 name-brand shocks. Given the price, I was a little worried about the durability and performance until I read some of the reviews. In the interest of science I decided to give it a test, and am I glad I did! The Salsa has always been a little soft in the back, sucking up power and making the bike less than effective as a cross-country racer. Higher pressure would help, but response suffered. The "pro-pedal" position had no effect. The DNM shock has transformed my bike and on the first ride with the recommended setup I beat my best time for our 10-mile XC circuit. Talk about impressed! The second loop was even faster. It has two chambers so compression and rebound can be finely tuned. There is also a rebound damping wheel and a lockout lever that actually works. I found the motion was so well controlled that I didn't need the lockout. Installation on the Salsa was difficult and required some tools that the average person might not have. Watch the video on Amazon as there are no instructions included with the shock! I needed to remove 2mm from the metal sleeves that insert through either end of the shock, and I needed to remove 1 mm from each of the plastic bushings that press over the end of the sleeve. They supply longer ones you can cut down if you have a steering column cutoff clamp but it seemed easier to take a little off the original parts using a bench grinder. The sleeve quickly heats up so I had to come up with a way to hold the part. After grinding I had to use a rat-tail file to clean up the bore and a mill file to clean up the ends. The bushings were easy to trim using the side of the grinding wheel. By the way, the video on Amazon that demonstrates modifications shows the metal sleeve being easily pushed out with fingers but I had to use a hammer and drift. All's well that ends well. Buy this shock if you need a replacement - you'll be glad you did.
