I need a front right replacement jack for my Grand Design 399th. Will this work for that or is there another part number?

Thanks for getting in touch, John. The Replacement Hydraulic Jack Assembly # LC25AF is a direct replacement for the leg on the first gen Lippert Hydraulic Leveling System. There is no way to look up your 5th wheel to know exactly what leveling system you have, so please confirm that yours is a first generation Lippert system. If you take a look at the top of the jack, the first gen jacks have a T-shaped top, the second gen jacks have a round top.

I have a 2021 Keystone Voltage. I need to replace the jack on the passenger side of my truck(right front side?) It looks like #LC25AF will fit and mine is first gen but in the description it said it replaces the middle or rear jack. Does this matter? Also, do y’all have an installation video? Thanks in advance. David

@DavidF Hey David. The Replacement Hydraulic Jack Assembly # LC25AF replaces the front leg as well so yes the placement really doesn't matter. I am sorry to say that we do not have an install video for this yet.

@JesseM What hydraulic fluid would be suitable for this installation?
