What Size Bolt Connects Lippert Gear Packs to Connecting Rod

Updated 03/30/2026 | Published 03/19/2026

Question:

What size and grade of bolt is used to connect the rod to the gear pack on the heavy duty Lippert Gear Pack LC123356. Not the bolts that hold the gear pack to the outer slide tube, the bolt that connects the two gear packs together to the connecting rod.

Hey Peter, the bolt size that connects slide out gear packs together on the connecting rod is typically a 1/4-20 bolt. Did you lose yours?

I did not lose it, it broke (well I believe it was over torqued and snapped at the shoulder). I was able to replace it be fore the remaining half of the bolt fell out of the gear pack shaft.

I reused my orginal bolts that were already in the old gear packs. Ibrlieve they were 1/4 20 bolts. I didn't pay attention to the grade of bolt because I figured it was already designed with that bolt and mine were fine. You should be able to see the grade by the markings on the head of one of the bolts that you have left. These replacement gear packs are great and 100 times better than orginal. You'll be happy you change them. Paul

@Paul they must be grade 8 that much I knew, with nylon lock nuts. The length not more then 1.5 inch but 1.25 is better. Know I know and will forever remember. I also used two flat washers one on each side of the rod to help hold the rod tight. Now someone needs to tell me the science behind using a round shaft in a square tube even a second grader figures this one out, it does not work well. In this case the bolt is holding all the torque. When will someone invent a square shafted gear pack that fits square inside the rod?
