Question:
What part of the arm do you measure for correct size for Slide out gear pack
asked by: Karen S
Expert Reply:
You'll need to measure the arm (pictured below) to determine the correct size gear pack replacement for your trailer's slide outs.
For 2" x 2" you'll need # LC281331
For 2.5" x 2.5" you'll need # LC123356
For 2" x 3" or 3" x 3" you'll need # LC140409
I've attached a short video below where I'll walk you through the replacement process. I do recommend using a floor jack and piece of wood to help lift the slide out box up slightly to take some tension off of the gear pack to make replacement easier.

I'm looking to replace my gear packs on 2012 Spring dale 266RL slide room. The video and photos are not showing measurement points in enough detail. So i don't trust my measurement. I think it is a 2x2. But im not sure how many teeth. Also, can i measure across the to top of the arm also to get correct measurement?
