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.

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.

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!

Apon opening the package they actually didn't look too bad, but that's where it ended. I planned on using these on a no prep drag build, first off the threading on the adjustable collars was full of burrs, once filled with shock oil they bounced like a pogo stick on 30 weight oil, 50 weight oil and you could feel some resistance in them but still bouncy, they were not smooth at all even with shock oil in them, the pistons must have huge holes in them because they had very little dampening, when I took them apart I found out they do not have piston plates with holes in them, they have solid metal washers that allow the oil to flow around them,tried to retro fit actual pistons from different manufacters like (associated,Traxxas,HPI) with no luck, so you're stuck with the washers, I ended up using 3000 wt diff fluid in them for the rears and 50wt in the front...the progressive springs seemed to work well but the overall lack of quality really shows, but again you "get what you pay for" do yourself a favor and buy good shocks from a name brand company. You'll be better off.

Good product

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.

Although the shock absorber looks fine, inside the tube where the rod slides, the walls have a thread-like texture as if it were a female screw, making the movement of the rod rough and jammed. Only 1 of the 4 works properly. You have to fill it with oil.

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.

Great shocks for the money, zero leakage..

Nice shocks for the price. Alittle bigger than expected but made it work. Seems to hold oil well with no leaks. Pleased with purchase.

Not as good as OEM (traxxas) but can be filled with out and a decent substitute for the price.

Beautiful. Wife wanted purple shocks and these look fantastic. It even comes with the hardware to mount them. (Shock bushings)

These do leak a bit but performance is very good for the price.
