Services both Straight & Curved Coil Springs
Includes U-bolts & wing nuts
Maximum diameter spring that the hooks will accommodate is 0.75".
Diameter of the rod: 5/8"

INSTRUCTIONS FOR STRAIGHT COIL SPRINGS:

1. Install 3 leg assemblies evenly around the spring. Turn nuts finger-tight to hold in position.
2. Install one U-bolt near the center of each leg with open end pointing away from the spring. Place the bar and wing nuts on the U-bolt, then finger-tighten the wing nuts
3. Tighten each leg nut a little at a time to compress spring gradually. Do not over-compress.
4. To release the compressor, loosen each leg nut a little at a time.

INSTRUCTIONS FOR CURVED COIL SPRINGS:

1. With the car raised and safely supported, place a jack under the lower control arm.  Raising the jack will compress the spring.
2. Install as many leg assemblies and safety U-bolts as possible (see #1 & #2 above), then finger-tighten the leg nuts.
3. Disconnect the lower control arm bolts, then slowly lower the jack until the spring can be removed.  The curved contour will remain.
4. To install a new coil spring, use one or more legs and U-bolts to produce the necessary curve.
