Another concern with spring-over is when lift blocks are installed between the leaves and the axletube. We have seen lift blocks break, fall out, and severely twist leaf springs. The biggest issue with lift blocks is that they add tremendous leverage to the leaf springs, and do not enhance the ride or performance of the suspension. Plus, lift blocks almost guarantee the need for some traction bars. Finally, we are not fans of lift blocks used under leaf springs on a front axle, as the added stresses of steering can make for a deadly combo.
