Coloured spots on coil springs ....

[Red Oktober]

This isn't really a tech question so i'll put it here (if that's ok??

Is there a reason why there's coloured spots on the coil springs .....

these marks are on all four of my coils ...

 

[clivehorridge]

Yes (probably) but goodness knows what it is...

is there any way to find out what the code/rate is ???

 

[cavanmick]

Ive never found one if there is...lol its a closely guarded secret... ive only had experience of it with the mercs but with them it wont give you the actual numbers just a series of colour codes to match up with.

Clive ... that link has just made my brain sore .... cheers m8 .. lol

Cavanmick ... it would be very handy infoif we could actually get the numbers so it would be easier to get the spring rate we wanted ....

ON a similar note (but of no use to decoding your springs), I recently bought OEM springs for my 2001 100 VX and they come with two options a pink and purple mark similar to the square on yours. In the Cruiser ones the purple are slightly longer and therefore heavier duty. I am told they were for vehicles with the reserve tank fitted. I opted for the purple as I have LPG tank fitted in the rear.
The mark is very small and difficult to notice initially.

Anyhow, pink, purple or brown paint dot is for the AHC springs. Pink is useless, purple is OK and brown is for most of us stock ahc 100 owners.

 

[sean butler]

Toyota are only offering Pink and Purple. Brown is not available or not being offered as an option.
I have no idea why.
I am referring to the main dealership here in Northern Ireland.
They did say there were 4 options but two of those were for non AHC trucks, leaving the Pink and Purple options.
