Front Rear RC Shock Absorber, 4-Pack Shock Absorber 108004 108mm Oil Adjustable Alloy Aluminum Shock for 1:10 HSP Redcat Volcano EXP/Pro Volcano S30 Truck Upgraded Hop-up(Silver)

Consider me impressed! I have zero experience with RC shocks, and I'm instead using these to build a shock-absorbing gimbal mount for my camera. When I first pulled these out of the package, I thought they were way too soft and bouncy for my purpose. But when I started tightening the spring adjustment, it became much stiffer. Adding 60wt shock oil from Team Losi Racing gave the shocks a very smooth action, reducing the bouncy feel a lot. I haven't mounted these on my camera plate yet, but I think they'll be more than adequate for bearing the weight and isolating the rig from road jitter. (I originally only used pieces of wire rope separating two metal plates, but the gimbal and camera combined were too heavy.) As for build quality, I'd say these are made from decent materials. The springs seem strong, the threads are well-cut, and the whole thing feels solid despite being light. The mounting points at the ends are plastic, but I think they're sturdy enough to last as long as you use the oil to dampen jolts. Bottom line, these seem like a great value. Just be sure to adjust them to your needs.

At first glance these are holding up and performing well after filling with shock oil. I am using these on a Hosim 9125 that came with terrible friction shocks so these are a solid upgrade from original. I had to reuse the original top shock mount eyelets because my shock hold offs are too small for these shocks. The gasket in the shock cap is a pain to get back in without tearing it (if you have to replace the top shock mount eyelet). I recommend these if you are looking for a low cost upgrade. KEEP IN MIND THESE ARE MEDIUM BORE. CLEARANCE MIGHT BE AN ISSUE FOR SOME.

They’re the best you can ask for from a $15 shock. They are smooth and work good on my crawler and have held up to abuse. However, after running these for about three months, the o-rings have started leaking pretty badly and I’m not sure if it’s worth replacing the o-rings as the shocks are so cheap anyway. If you want longevity maybe look at spending a little more to get something that’ll last a bit longer.

Needed some inexpensive shocks for a knock around build. I was impressed with the quality of these. Threads were nice and once filled, no leaks. I'm sure if using for racing may not dampen as well as more expensive units but worked perfect for me.

One of the shocks leaked oil from the moment it arrived. I topped the oil and lubed the o-ring on each one before installing on my 9125. https://www.amazon.com/gp/product/B07NY9BJ1B/ref=ppx_yo_dt_b_asin_title_o04_s01?ie=UTF8&psc=1 During my first run with these new shocks, the eyelet snapped on the leaking shock. The other three seem to have held up just fine. Other than this one dud shock, they have performed exactly as expected and greatly improved the handling of my RC.

just a friction shock that you can add oil to. Has no damping function at all. Inside its just a loose washer that lets the oil flow around it. No holes... so the shaft is loose and doesn't stay on center so all the oil flows around the larger gap on one side or the other. Works ok as just a friction shock

I bought these just on a hope they would suffice for some lower use builds. Upon receiving them I pulled them out of the packaging hopeful to find something usable, Unfortunately that was not the case. To start with the lower shock O-rings do not fit inside the lower shock. The diameter of the shock is incorrect to the O-Rings. The shock has a light amount of extremely heavy oil, guessing 3k diff fluid. Even with this the shock is already leaking. Besides the lower o-ring issue the piston is a solid metal washer that doesn’t touch the sidewalls of the shock body. This is a major design issue as it allows the shock shaft to wiggle back and forth in any direction. This also promotes leakage since not only does the incorrect o-rings need to maintain seal as the shock travels on a vertical but it also needs to try and seal travel on horizontal. These are a complete joke! Do not under any circumstances if you are serious buy these.

This is the frame to an RC monster truck I am building. I was shocked when I received the shocks. So high a quality for such a low price. It's great!
