(applies to model year 2019 and later)
The Mammoth can be converted from 110mm rear travel to 140mm rear travel by ordering replacement control arms (rocker arms)
The Behemoth can be reduced from 140mm travel to 110mm rear travel by ordering replacement rocker arms.
The Lunchbox and Sesh cannot be converted to a different rear travel.
If you have a Fatillac originally built with 4″ (110mm) or 5″ (140mm) rear travel, you can convert between 4 and 5 inch by swapping rocker arms. If you order with 6″ travel, you cannot change it. Go big!
