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.
