FACE TO FACE MEASUREMENT
This is the measurement from the outside face of one hub to the opposite one. See A below.
SPRING MOUNTING CENTERS
This measurement is from centre to centre of the springs. See B below.
Measurements A & B are required plus C which is the required depth of the bend. This can be 60mm, 90mm or 120mm. See C below.
DROP BEAM AXLES
Measurements A & B are required plus D which is the required height of the drop. This can be 60mm or 90mm. See D below.
If you do not know the A and B details above then the following information is required:
• Chassis overall width. Minus 50mm. This gives spring centres
• Overall measurement outside the mudguards. Minus 30mm. This gives outside to outside of the tyres
• Inside & outside offset measurement of the wheels with tyres fitted. From this together with the mudguard measurement, the hub face to face can be calculated.
