A balanced trailer rides smoother and tracks straighter. This kit includes (2) 1-1/2" tall front hangers and (2) 7/8" tall rear hangers with steel bushings, giving your double-eye springs a solid mounting point and proper geometry. It works with single axles rated from 2,000 lb to 7,000 lb, achieving about 4-1/4" to 4-1/2" clearance between the trailer frame and the axle depending on axle size. That setup helps maintain correct ride height and reduces sway while towing.
Each kit comes ready with (4) 3-1/8" long shackle straps, (6) 3" x 9/16" diameter shackle bolts, and (6) 9/16" diameter locknuts. The shackle straps bolt to the outside of the rear hangers for smooth pivoting and secure travel. Locknuts keep everything tight without over-torquing, so the suspension moves freely without binding under load.
The larger front hangers measure 3" long, 2-5/16" wide, and 2-1/8" tall overall, while the smaller rear hangers measure 2-1/8" long, 1-13/16" wide, and 1-1/2" tall. They’re designed to work with standard 1-3/4" wide double-eye leaf springs for an easy fit. The widths make welding straightforward on a typical 2" trailer frame so your suspension sits square and even.
The included table provides reference distances for common double-eye spring models—20" between hangers for a 1-3/4" axle and 24-7/8" for a 2-3/8" axle. These measurements are starting points so you can mock up your setup before welding. That ensures correct hanger placement and proper shackle angle once the trailer is loaded, giving you confident handling every time you tow.
| Leaf Springs | A - Distance Between Hangers | B - Distance Between Center of Axle and Trailer Frame | Axle Diameter |
|---|---|---|---|
| SP-169275 (1020) | 20" | 4-1/2" | 1-3/4" (typical 2,000-lb trailer axle) |
| SP-219275 (PR722) SP-220275 (PR3) SP-218275 (PR4) SP-212275 (PR4B) SP-111275 (PR5) SP-198275 (PR6) | 24-7/8" | 4-1/4" | 2-3/8" (typical 3,500-lb trailer axle) |

Thanks for following up. I used your product on a motorcycle trailer I was building for a trip I made last year. Im extremely impressed with the quality of your product, and also the affordable pricing! I had two Harleys on the trailer with a total worth of about $65,000 and we hauled them from Nevada to Ohio and back with zero issues and your product performed flawlessly. Thanks so much again

Phil, thanks for your business and your review. Since the required U-bolt lengths and diameters vary from axle to axle, the mounting components are sold separately. The U-bolt kits may be found at this link:
