The GKTECH high tensile offset steering rack conversion extenders offer 3 primary benefits; offset rack spacer moving the rack forward to eliminate steering bind on high lock setups, unique to our design these convert the tie rod thread from the uncommon M18 to a much more common M16 and they offer more steering rack travel which in turn gives more steering lock. Offset rack spacers are a great alternative to moving the steering rack forward. Relocating the steering rack is expensive and in some cases just not possible. This product converts what are normally an 18mm inner tie rod thread to a 16mm inner tie rod thread which is a much more common size (such as S-chassis, Skylines etc.) In addition to converting to a more common tie rod thread this rack spacer set offers a grand total of 16mm of rack travel equating to around 12-15 degrees of extra lock without compromising on the amount of thread left in the steering rack.
