Pretty good collection of what's needed; could be a bit better.
Great stuff, and the ones that arrived for me were better than the ones on the bike, showing RM upgraded the hardware over the span of this version of the bike. A tiny bit uneven, from the perspective of someone bringing a 5 year old secondhand bike up to snuff. Please consider adding a pair of the plastic cosmetic dropout pivot plugs that keep dirt out of the backside of the dropout pivots; those plugs seem to go missing (auto supply stores sometimes have something that fits, but it's an unusual size). It's nice the kit includes all four internal pivot spacer washers-- realistically one usually needs to replace only one, or rarely two of these at a time. On the other hand there's a very specific countersunk outside spacer washer for the front shock bolt-- there's no alternative to this one and it really does wear out and/or go missing; be great if there were two instead of just one. There doesn't seem to be a kit containing just the two shock pivot bolts for the 2018-2021 Altitude, but there is one for the newer Altitude; unfortunately only one of those bolts fits the earlier model. Shock bolts wear out, so I sort of wish this kit included two of each black shock sleeve bolt that directly connects the shock (the silver screws outlast the sleeves, so the kit is fine for those).
