Leaf Spring Measurements

Hi All,

Can anyone tell me what the inside diameter of the "mounting loop" or "spring eye" of some springs for a sierra are.

I know they are different at both ends, i'm after the measurement for the larger end (which i believe is the solid chassis mount end - rather than the shackle mount end).

Thanks,
Greg

40mm for the fixed mount end
30mm for the shackle end

Thanks mate...

Back to the drawing board again.

Anyone know of a Johnny Joint that is only 40mm in diameter? The BBO Bullocks are 50mm :cry:

I don't suppose you could tell me how wide the spring is could you? Again - at the eye's.

Thanks

It's not terribly expensive to get aone leaf custom made .. for say a main leaf with a 50mm eye to accomidate the bollock .. I got quotes ages ago on longer main leafs .. it was about 80 or 100 bucks ..

no i measure my spare rears a few weeks ago that's all

the eye measurements are spot on

get ShortyMQ to make the springs for you

he made some with 50mm eyes for the same reason

Nice work NAM...

I guess the trick would be to find a set that are 40mm in diameter - that would allow you to fit them to a stock spring and keep the costs down considerably...

Check out these ones - they must only be 30 or so mm i guess to fit inside the rancho shock eyes right?

Hey NAM,

I've got a couple more questions for you if you've still got the spring under your desk...

1. how long is a rear Old Man Emu spring (i want this to be eye to eye but following the bend in the spring) - i.e. how long would it be if it were completely flat.
2. how much longer is that then a stock rear spring - again, measured as though it was competely flat.

Thanks

these are stock sierra springs

Zuk fronts ~ 37" e-e, ~ 255lbs/inch
Zuk rears ~ 40" e-e, ~ 155lbs/inch
