Blox has decided to call this new knob the "490 Spherical". Sounds a lot like 490 Round doesn't it? =) I'd like to say Inline Four had an influence on the naming of these new knobs =). The 490 derives from the actual weight of the shift knob, 490 grams. This knob is heavier than the usual Blox knobs you are familiar with. It's round design and heavy weight will surely provide a positive feel and shift engagememt.
Like all Blox shift knobs, they are constructed out of aircraft quality aluminum and feature a high quality inner thread pitch, so cross-threading is never an issue. Also, since there is no "shift gate" pattern, you can use it on a 5 speed or 6 speed equipped vehicle. A small Blox logo is laser etched on the top of the shift knob.
Note: These shift knobs have a thread pitch of 10x1.5 which fits Honda's and Acura's.
