Offset 1" Zero Rate Add a Leaves™
Fits any vehicle with spring-over suspension and 2.5" or 3" wide
Nearly all Chevy trucks use 2.5" wide
springs at the front and rear. It's a common misconception
that the '67-'87 ('91) Chevy front springs are 3" wide because
they are nearly 3" wide at the ends but they taper to ~2.5" at
the middle. The vast majority of Chevy trucks need our
2.5" zero rates.
Part #U8003 (for 2.5" springs) - $40.00
Part #U8001 (for 3" springs) - $45.00
and Suburbans sit low in the rear, and a lot of truck owners
also want to relocate their axles forward or back a little for
better fender clearance or for a bit more wheelbase and
driveshaft length. This is the answer to both problems.
probably asking about the name. Well, we didn't want to call
them blocks since they're really not a true block, they bolt to
the spring pack just like another leaf. We didn't want to call
them add a leaves since most people think add a leaves will
stiffen the springs. So they're an add a leaf that won't stiffen
the springs, they add "zero" to the rate.
leaves are CNC machined solid steel with offset holes to allow
you to move the axle 1" or 1.5" forward or backward from the
spring pin location. You can also leave the axle right on the
spring center pin if you like and only use them to raise the
truck 1". The top corners are radiused to prevent stress risers
in the spring pack.
are a true bolt in leaf, they are safe to use on the front or
rear suspension for extra ride height or to relocate the axle. To use the offset, you bolt the leaf to your spring using one of
the offset holes and cut the center pin off to bolt into the
leaf in the center hole. This will move your axle forward or
backward 1" or 1.5" depending on which hole you use and which
way you mount the leaf.
To mount the leaf centered on the spring, you simply run the
full length center pin through the center hole of the leaf and
through the pin hole in the spring pack.
includes the machined "leaves" along with new center pins and
bolts to install them.
You will have to drill a hole in the ubolt plate for the new
offset spring pin location. You will also need to make sure your ubolts are long enough, you need to have 1" or more of extra
thread to use the Zero Rate™ kit. ORD has ubolt kits available
to accomodate the extra length if yours won't.
applications with crossover steering be aware that you will be
losing clearance between the draglink and your RH spring. The

there - make sure to check it out.
