If the rear end in a leaf spring car is mounted directly to the leaf without a lowering block will it give you more traction???? Or does it do nothing????

lowering blocks only lower the rear of car, and some are angled for pinion angle..

Thanks for the reply. However, I was just wondering if the rear end would have more leverage on the leaf spring and therefore create more forward bite if mounted directly to the leaf rather than having a 2" or so lowering block. Does anyone else have any experience with this?

Adding a lowering block lowers the rear roll center, it would now sit 1/2 way between the axle housing and the spring. Lowering blocks also tend to soften the spring rate at the wheel.

Lowering blocks do affect the amount of leverage the torque the axle puts on the spring. Very slightly though. If it would be possible to run the spring straight thru the axle, you would be at optimum leverage. You will not notice a loss of forward bite until you have reached a 3" block.
