I need a replacement inner tube for my Lippert power tongue jack for Ground Control Travel Trailer 421366. Would you have this? Do you also have a parts breakdown for this model tongue jack? Thanks!

Hello Lyle, thanks for reaching out. We do carry the Replacement Tongue Jack for Lippert Ground Control TT Leveling System # LC421366, but I am sorry to say we do not offer any replacement parts for this jack. If you are needing parts, your best bet will be to reach out directly to Lippert. They should have access to the parts breakdown and may be able to provide the parts you need.

@JesseM unfortunately not. I had to purchase a new entire jacket.

@LyleL Ok I see. I guess the jack just isn't repairable like some are. Glad to hear you got it sorted out though. Feel free to come back anytime you need anything!
