Caltrac Tuning Info LOOK HERE

Interesting. So these assassin bars, do they require mods?Do they need a special spring?What's the cost vs a Caltrack?
They're the same price as the caltrac for inboards.
They will work with any leaf springs.
I don't believe any mods are required.
I'm getting closer to installing mine, I have some mods to do but nothing pertaining to the assassin bars
