1.
With car on flat surface, measure and record front and rear ride
heights to use as baseline.
2.
Remove front spring. Caution:
Front spring is loaded!
Consult Chevrolet Service Manual for proper removal method.
3. Remove two rubber blocks
located on top of spring by cutting off flush with spring. Any
cuts to spring could accelerate spring failure!
4. Rough up surface where
blocks contacted spring using coarse sand paper or emery cloth. Clean area thoroughly with solvent such as
brake-clean.
5. Apply weather stripping
adhesive or contact cement to spring and flat side of wedges. When adhesive becomes tacky, attach wedge to
spring where blocks had been removed.
Hold wedge in place with masking tape.
6. Only after adhesive has
cured, lubricate new blocks with lithium grease.
7. Reinstall spring using
procedure from Chevrolet Service Manual incorporating following changes:
- Tighten lower control arm bolts to 46 ft/lbs;
- Drive car around block to settle front suspension.
- Without raising vehicle, tighten lower control arm bolts to 96
ft/lbs (This will keep lower control
arm
bushing from being put into torsional load.)

It is imperative that vehicle be realigned after ride heights have been
adjusted to avoid unusual.
And expensive tire wear.
NOTE: This application will lower frame approximately 1-inch depending on age and psi of current spring. An additional ¼” to ½” can be gained by removal of factory shims.
