In the June '92 issue Truckin' magazine, we showed you
how to install Classic Performance Products new front end disc brake and
lowering conversion for the '67-70 Chevy trucks. Now we will show you how
to attack the rear of those same year trucks, including the '71-72 models
as well, to make the job a complete success. As we stated in the previous
article, by converting your truck's braking system to a disc format,
you are changing the bolt pattern from six-lug to five-lug. So that you
don't have two different types of bolt patterns, it is recommended
that you either re-drill your rear hubs to the same five lug pattern or
swap rear ends for a unit that possesses the desired lug situation.
A half-ton '71-72 pickup model rear end is an easy bolt-in
for this instance and has the five-lug pattern you will need. While we were
making things right in the back, Classic Performance Products went ahead
and installed one of their new lowering kits for these same year pickups.
The'67-72 trucks are factory equipped with trailing arms and progressive
coil springs in the rear which can be difficult to lower if you don't know
where to look for the right products. Classic Performance Products has just
recently introduced a new line of lowered rear springs to get the job done
right. By installing a set of these lowered rear springs, you can
lower the rear of your truck either four or five inches, depend upon which
spring you desire. In this case, we installed a
four inch version and then added another Classic Performance
Products item, a custom made 1-1/2 lowering block to the suspension. If
you can add, that's a total of 5-1/2 inches lower than stock while retaining
a smooth ride. The new lowering block kit for the '67-72 Chevy trucks
is made of high-grade billet aluminum and comes with new extended "U"
bolts for a complete installation. If you are interested in getting
your early Chevy down in the weeds while maintaining a decent ride, check
out these two new products from Classic Performance Products.
