These arms have a new design that shifts the shock mounting point out towards the wheel for added high speed stability. These are backwards compatible with the original EB/NB but must be used in conjunction with the new front shock tower (TKR5268). Original spindle carriers (TKR5042/TKR5042B) and spindles (TKR5041) are compatible as well as the newer spindle carriers (TKR5194) and spindles (TKR5193).
Note: these arms are not left right compatible.
