Video Transcript for Review of Redline Trailer Leaf Spring Suspension - Suspension Bolts - 38-4TB

Hello everybody, this is Jeff at etrailer.com. Today I'm gonna take a look at this 3/8 inch diameter by four inch long Leaf Spring Center Tie Bolt with the nut. Now, this is a replacement Spring Center Tie Bolt that is used when replacing a leaf or adding a leaf to your leaf spring's suspension system. Basically this Leaf Spring center bolt is a piece of hardware and it's finely threaded down the entire length. And it has the round button head at one end. The other end is designed to accept this included nut.

Now this bolt performs double duty by holding the spring leafs together and centering the spring pack in the axle housing. Just wanted to pop up an insert to show you what we're talking about. If you look there, you can see this leaf spring and this is right in the center of it that holds those springs all together. Basically that bolt will run through the holes that are punched in the center of the spring leafs and when the spring is assembled, the center bolt is installed and the nut is put on there and torqued. Then when that whole spring is installed in the vehicle the round buttoned head right here on the center bolt will be used to position the spring in a pocket in the axle.

The spring bolt head will locate the spring and ensure that the axle will be in alignment. We mentioned this is 3/8 inch diameter. The length of it is always measured just under the head. So there's your four inch length and it does include the one bolt and the one nut. But that should do it for the review on the 3/8 inch diameter by four inch long Leaf Spring center tie bolt with the nut.

  • 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.
