landcruiser 100 series stud patterns

can't help with when they changed, i thought all 100 series were 5 stud but i could be wrong. IFS have a different offset in the rim to live axle models though, that much i do know.

Any 100series landcruiser with the factory TD (2000-2007) or Petrol V8 motors will have IFS.

Any 105series Landcruiser with the 1Hzzz (1998-2006) normally aspirated diesel motor or 4.5litre 6 cyl petrol motor (1998- about 2002) will have a rigid front axle.

The stud patterns are all 5 stud, but the RFA have zero offset, while the IFS have 60mm of offset. 60mm is a lot, so you have to specify offset if you want the wheels to match.

The caravan brakes will most likely come from "Vehicle components". Check with your caravan manufacturer if this is their source.

All the manufacturer will need to do is ask for 100 series stud pattern and they will know what to supply.

The stud pattern has not changed from 100 series to 200 series.

The Landcruiser stud pattern is 5/150pcd. Another words they are 5 studs on a PCD of 150mm. They all run 14mm suds and are all the same from early 100's through to 200's and the new 76 series wagons/ utes.
As mentioed above the critical thing is the offset.
Vehicle components or ALKE can help you out if required.
