› WHAT YOUR LEAVES SHOULD Good
SHACKLE ANGLETH AND SPRING LENG Leaf springs are quite simple, yet it seems that very few people understand how to get them performing off-road. You see all sorts of ridiculous methods being used on the path to leaf spring nirvana, such as heavily arched springs to gain ride height, drop (wacky) shackles, or those who fit overlyextended shackles and wonder why their vehicle now rides terribly. The secret to a good ride and off-road performance from a leaf spring revolves around the shackle angle and spring length, then matching a shock absorber that is long enough on extension and compression.
› 450 shackle angle
› Vertical shackle
› Inverted spring
This is the shackle angle you should be aiming for
A vertical shackle will ride firmly as the spring is unable to compress. Go too far flat and you will be on a one way trip to body roll city. So how do you get it right? A 45 degree shackle angle is what all the cool kids run. Many raised leaf springs are actually shorter than stock, and have additional radius (arch) built into them to simply achieve a lift. This is lazy engineering and cost cutting at its finest. A good aftermarket leaf spring will be longer than stock, keeping the shackle angle at its happy place while still providing a lift.
