See what our Experts say about this Redline Trailer Leaf Spring Suspension

  • Availability of Trailer Suspension Shackle Bolts in 4-inch Length and 9/16-Inch Diameter
    We do offer leaf spring shackle bolts as separate items. The linked page will show you all lengths, including 4-inch and 4-1/2-inch. In your required 9/16-inch diameter the longest bolt we have is the Redline # 34007-187-00 which is 3-7/16-inches. The 4-inch and longer shackle bolts are different diameters, such as the Redline # 38-4TB which is 4-inches x 3/8-inches diameter. You will be better off using hangers of the correct width for your 1-3/4-inch springs, rather than shim them....

  • What Replacement Hardware do I Need to Use with My Slipper Springs # # SP-161275?
    For the axle U-bolts, we have two different options: - 3" Round Trailer U-Bolts 9/16" Diameter # SP01-080 - 3" Round Trailer U-Bolts - 1/2" diameter # SP01-060 Since these bolts are so close in diameter, I recommend measuring the specific diameter of the bolts you have. For the spring-eye bolt, the correct bolt is the Spring-Eye Bolt with Locknut for Slipper Springs - 3-1/2" Long # 166079 As for your broken 3/8 inch bolt, we have Leaf Spring Center Tie Bolt with Nut, 3/8" x 3" # 38-3TB....

  • Bolt Recommendations for a Equalizer for 2 inch Slipper Springs
    For the Equalizer for 2 inch Wide Slipper Springs # TREQ1344 you will want to use a Wet Equalizer Bolt with Castle Nut and Grease Zerk # TRFA71063 for the center bolt hole. This bolt has a grease (zerk) fitting. For the side bolt hole that the spring will mount to you will want to use a Spring-Eye Bolt with Locknut # 166079. For a keeper bolt you would want a Leaf Spring Center Tie Bolt with Nut # 38-4TB. I attached an FAQ article on slipper spring suspension setups for you to check out also.
