1999-2007 F250 F350 Rear Leaf Spring – Ford 43-1261

The 43-1261 is a 4 leaf spring with a bottom overload totaling to 5 leafs. This was the most popular spring on Ford 1999-2007 f-250/f350 model pickups. If you are looking to replace your springs you should follow these instructions carefully-

  • If you are only looking to replace leaf spring on one side of your truck- verify that the spring you are replacing has 4 leafs with an overload on the bottom. If this is the case- this spring is the correct spring to replace your old one. If you have more or less leafs in your spring pack, feel free to give us a call and we can get you the correct replacement. If your truck has top mounted overload leafs on top of the spring- you will re-use these. (see additional information below for more information on overloads)
  • Note- if you replace spring on only one side of the vehicle  it will most likely cause the vehicle to lean to one side. This is because the new spring will hold the trucks weight differently than the older fatigued spring on the opposite side. It will work, however It is strongly recommended that you replace rear leaf springs in pairs.

1999-2007 Ford F250 F350 Leaf Spring Replacement for 2 or 4 Wheel Drive Trucks

The 43-1261 is a F250 F350 Leaf Spring for Ford Super Duty pickups. It is a quality replacement for your old, weak, broken or sagging original leaf spring pack.

The 43-1261 rear leaf spring  is manufactured by Dayton Parts in the USA. It replaces the Ford’s OEM part # F81Z5560BA  or F81ABE or F81A5560BE

The 43-1261 meets or exceeds OEM quality specifications. Leaf springs from Dayton parts undergo a process of shot peening of all the leafs. Stress peening heals over the imperfections of the leafs and can greatly improve the life of leaf springs. Studies have shown that leaf springs that have been stress peened vs. those that have not last up to 3 times longer!   Many competitor leaf springs do not undergo this process. For more information see- Davton Vs. Competitor Springs

If you need replacement U-bolts, eye or shackle bolts, shackles, or shocks- These will appear as options for you to select in your cart.
