Question:

I am looking to upgrade my axles and suspension on my 2017 Grand Design 29RS fifth wheel. It came with 4400lb axles and the newer models have 5200lb axles. Current 4400lb axle tag info is LCI35-SB-86.5-68.5-NOSP-0S-L-655-7278-30PT-3-GAWR 4400#. Newer axle tag info LCI52-SBSA-86.5-68.5-NOSP-OS-L-65516-7225-BRONZE-30PT. Do you have a Dexter replacement axle and suspension system?

Helpful Expert Reply:

What you're looking for is an 86-1/2" long replacement axle. Since you will need new hubs and drums, along with brakes, I recommend getting the # 8327816-EB. This has a 71-1/2" spring center length so you will also need to cut off the spring seats and weld on # TRSS300 to match the current 68-1/2" measurement.

Grand Design does a great job listing their parts, but unfortunately they don't include the leaf spring information. You will need to measure your current leaf springs to find the right replacement. That is the spring eye to spring eye measurement.

If they have fallen flat over time you will also need to account for that. You need to choose a replacement that matches or is close to the same length. For capacity, as long as they are rated for 4,400 lbs they will work, it doesn't have to be 5,200 but certainly can be. I would also double check your current axle diameter, it is probably 2-3/8". The new axle will have a 3" diameter so you will need # CE23003 to mount the leaf springs.

I have attached a link to all of our available leaf springs for your reference. If you want to send me your measurement I would be happy to check for you and see what the best replacement is.
