Hey David, there actually isn't a difference between the Slipper Spring # e36SR and the SP-177275. We just use a different part number.

Hey David, did the slipper spring end up being the right match for your trailer axle? Knowing how it worked out could help others comparing those part numbers.

@JamesonC I ended up buying 2 of these: EM28UJ 2-Leaf Slipper Spring for 1,000-lb Trailer Axles - 24-1/4" Long - EMCO They were the perfect fit for my Carry-On 4x6G Utility Trailer with 2K axle. David

@DavidT Thanks for passing that on! I am glad the part # EM28UJ was correct fit for your trailer!
