Raising Trailer Suspension To Clear Rear Leaf Spring From Hitting The Crossmember  

Question:

Expert Reply:

It appears you may have installed shackle straps which are longer than what you may have had. It appears your straps are either 3-1/8" # TRSL313 or 3-1/2" # TRSL350 and you likely only need a 2-1/4" # TRSL225. This would move the mounting point closer to the axle and raise the trailer approximately 1/2". To get enough height to clear your crossmember you will likely need the Lift Kit # RR23QX. This will allow you to raise the suspension either 1-1/4" or 2-1/4" to clear your rear crossmember.

On a 4,000lb 25-1/4" Leaf Spring # e93SR the spring only has a height of 3". The 4,000lb 26" Leaf Spring # e48SR has a height of 4-1/4". So by going to the shorter spring you will most likely lose height depending on the height of your current springs.
