Rick V Verified Owner Thursday, Jan 11 2024 (about a year ago) Team Losi Racing Mini-B Pre-Assembled Aluminum Rear Shocks (2) I purchased a set of both the front and rear shocks and am writing this review for both as my experience was the same for both sets. The build quality of these aluminum shocks is quite nice, however I very quickly noticed some major design flaws that render them almost useless, if you intend to ever dissemble them. There are small, thin O-rings that are used in both the rebound collar adjuster and also under the bleeder shock cap; these are the weak point of this entire package. I dissembled these pretty much out of the box as I knew I wanted to run thicker weight oil; the first issue I encountered is the O-ring that goes under the bleeder cap is so thin and flimsy, that even the tiny amount of pressure from just finger tightening the cap causes the O-ring to twist and pop away from the shock body, which doesn’t allow a proper seal to form. I tried just removing this O-ring entirely as I could not get it to sit flush after many attempts and it doesn’t seem that the tolerance of the machining of the cap and body alone is tight enough to prevent oil from leaking out, as after just a couple pumps of the piston, oil was already coming out from under the cap. The other issue, as noted also in the other review below me, is the O-ring in the rebound adjuster collar. I’m assuming the intent was to have this in the collar to keep it firm and prevent vibration from spinning the collar, however, this O-ring is too thin and after just a couple of turns of the finger, the entire collar gets stuck on the O-ring binding in the threads, and you can’t get it to spin without pliers. I was able to work it back and forth enough times to get the O-ring to pop out entirely, which freed up the collar and allows it to spin like normal now.
I’m going to attempt to find an O-ring of similar diameter for the shock caps either at my LHS or hardware store that won’t fold under finger tight pressure, but if I can’t find something, I’m afraid I’ll have to try returning these as these are basically useless if I can’t keep the shock cap from leaking oil. It’s a shame because the shock body, piston and machining of all the metal parts seem top-notch. But these fragile O-rings are an Achilles heel and basically make this product unusable for me. 3 customers found this review helpful. Andrew Stanton Verified Owner Thursday, Jan 4 2024 (about a year ago) Team Losi Racing Mini-B Pre-Assembled Aluminum Rear Shocks (2) They seem very nice, put them on my buggy, ran it to test it out, when I went went to make adjustments, the screw on the shock was stuck in place and will not move. I don’t know if the aluminum threads are binding or what’s going on. I cannot adjust ride height or range of motion. Ended up throwing the stock shocks back on and will be buying different shocks. 2 customers found this review helpful. Andrew Gabriel Verified Owner Thursday, Mar 21 2024 (about a year ago) Team Losi Racing Mini-B Pre-Assembled Aluminum Rear Shocks (2) If there was a way to keep the gasket on the top from leaking I would love these. But unfortunately they brake as soon as you open the top. 1 customer found this review helpful. mini b 4 life Verified Owner Tuesday, Sep 10 2024 (about a year ago) Team Losi Racing Mini-B Pre-Assembled Aluminum Rear Shocks (2) Overall shock is pretty good and it is nice that they allow you to open up the top of the cap. However, the shock colors get quickly fused onto the shock body because the O-ring is the wrong size. Scavenged all over the Internet and outside of ordering custom O-ring there are no sizes available that will fix your problem. The only solution is to simply remove the O-rings and then constantly check the preload and height of the vehicle as the collars will move there is no O-ring or way to lock the collar.
