Question:

Hello, What type of bolt is recommended for the slipper end of this slipper spring? I am using this on an ez loader boat trailer with a single axle. From your website the best I can find is #166079. I would use this for both the bushing end and the c hook slipper end. Is that recommended? Alternately I have #166081 shackle bolts that are 3inch long but seem to be long enough for my application. Could those be used as well? Thank you for your help!

Expert Reply:

For the spring eye you would use the Spring-Eye Bolt with Locknut for Slipper Springs - 3-1/2" Long # 166079, but slipper springs don't have the second spring eye, so a bolt is not used on the back end. You can also use a wet bolt like # 126B2, for less friction. The Shackle Bolt with Locknut for Double-Eye Springs - 3" Long # 166081 are for use with the spring and shackle straps used with a shackle straps on a tandem setup with an equalizer but it could be used for the springs and the hanger bolt.

For slipper springs you will want slipper spring hangers like # APS6SE. You will want to match your spring width.

If you have traditional spring hangers, you will want the 6-Leaf Double-Eye Spring for 4,500-lb Trailer Axles - 26" Long # e27SR and the second bolt.
