You need to measure the box into which the steps fit. The box is probably 27 or 27.5". The Alumi-Tread steps are 27.5". It's possible to squeeze the 27.5 steps into a 27 box. Lippert did that on ours, but the steps always had a bit of a bind when folded up or down.
I just installed the 25.5"
Glowstep Revolution steps with spacer kits to close the space inside the box. More expensive, but much nicer than the Alumi-Tread. They adjust to several positions to fit the terrain and sit securely on the ground so there's no flex or bounce. A number of people on the forum have recently installed the 27.5" Glowstep Revolution without spacer kits. At least one person made it fit into a 27" box.
Perhaps your steps were bad. Both of my steps were replaced by Lippert (I did the work, they shipped two sets out, no charge).
Mine were binding and required an excessive amount of force to open.
The Lippert steps fit in the toy hauler without cutting out the top bar that was done on many of the non TH trailers at Goshen.

Any idea if there are different sizes? I just want to make sure what I purchase will actually fit? I think I am more concerned about the width to make sure they bolt in correctly.
Don't know about different sizes, but you definitely want the 4 step version for a Cyclone.

Dan's right, the Glowstep Revolution steps are definitely an upgrade. The Lippert Aluminum tread steps are lighter then the OEM. But they won't solve the issue of dealing with unlevel sites (having to add a separate step, or having the last step too close to the ground).
Did you get the 4 step version?
I have not used the extra ground step since putting the 4 tread step unit on (with the front door, the rear door has always been an issue).
And I have never had a step "too close to the ground".
Almost on the ground, maybe even touching, but LevelUp can take care of that if it was an issue.

Besides the advantage of the 4th step, the overall rise from step to step into the trailer was reduced some, also a benefit.
