In order to get the correct size leaf spring for your 2003 Forest River Sierra F37 you need to measure from center of one side of the spring roll to the other with no weight on the axle. There are different length springs for a 6000lb axle.

If your spring eye measurement is 26" you need 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 26" Long Item # e94SR.

If Your spring measurement is 25-1/4 you need 5-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 25-1/4" Long Item # e34SR.

I also recommend replacing your spring bushings with Never Fail Bushing - 9/16" Inner Diameter, 11/16" Outer Diameter - 1-3/4" - Qty 1 Item # TRBU11566. These bushings are self lubricating and maintenance free and should only be used with standard leaf spring bolts not wet bolts.

If your bolts become damaged when removing them I recommend replacing them with Zinc Shackle Bolt with Locknut for Double-Eye Springs - 3" Long Item # TRFA73Z916DLNZ
