ORD Heavy Duty Front Shackles
Application: ’69 to ‘87(to ’91 for Blazer/Sub and
K30) GM
Description: After
watching a ’77 GM ˝ ton limp across the Golden Spike trail on a
broken front shackle and seeing serious wear marks on the frame
rails of lifted trucks from spring impact, we did something
about it.
This shackle kit increases the bolt size from 7/16" to 1/2" and
increases the side-plate thickness to 3/8" for improved
durability. The bolts are Grade 8 for maximum strength.
Also, we make the shackles 1/2" longer than stock to help keep
your lift springs from hitting the frame plus gold zinc plate
them for corrosion resistance. Includes new poly bushings
for the upper shackle mount and the leaf spring end, the new
sideplates, and all the bolts, sleeves, and pinchlock type
locknuts.
The greasable shackles use drilled and cross-drilled bolts
and drilled inner sleeves to channel grease to the bushings.
You'll get longer bushing life, a smoother ride, and virtually
eliminated squeak with the greasable kit. We use ORD exclusive
hard compound bushings for greater bushing life and recently
upgraded to a 4130 chromoly steel sleeve for even more
durability.

springs) $75.00 Call 970-945-7777
If you have stock springs, please call and
specify, you'll need a slightly different bushing set.
We also carry a greasable main eye bushing kit for the
front leaf springs to make the front suspension fully
greasable. This kit includes bushings, bolts and sleeves to
make the front eye of the front springs greasable.

Tech Notes:
-
About
95% bolt on. Requires changing the bushings in the leaf
spring end and installing a urethane bushing kit in the
frame part of the shackle mount. Both are pretty simple,
remove the old bushings, put in the new.
-
The
same spring length changes that mess up the swaybar geometry
also create problems with the front shackles. A longer
spring will come back farther on full compression and with a
stock length shackle, will probably hit the frame. This
provides a really harsh bottom out and cause a lot of extra
stress on the frame and spring hangers. That’s why our
shackles are longer than stock.
Due to varying vehicle configurations, we cannot guarantee
that the springs will not hit the frame when using our
shackles.
-
Why
aren’t they longer yet? Extra length on a shackle gives you
more caster (which isn’t too bad in moderation) and tips
your front pinion down. The pinion angle can quickly get to
the point that the yoke has to be clearance ground for the
driveshaft to rotate. This can be a major problem and is the
reason we keep the extra length to a minimum.
-
In 1988
the factory introduced a longer front shackle on K5's,
Suburbans and some 1-ton trucks. These shackles are the same
length as our HD shackles.
