why bother? it'd be a downgrade, imo. the air spring is dead reliable, infinitely tunable & lighter. plus there's no spring to stantion rub. i love my wc air.Don't know any of this stuff yet, or anything about Boxxers at all, actually, but hoping to pick up a WC soon. Is there a "kit" for this conversion? Do I just call RS and tell em I blew the Solo air cartridge and I need the Spring Upgrade? Is it Team parts?
