We have a wide selection of steps available so I am certain that we can locate a suitable replacement step for you. While I can not provide you with an exact part number for your current steps installed by the builder of your 2014 Keystone Cougar Half-Ton Fifth Wheel, I can locate options. From what is available to me online I suggest the Alumi-Tread Manual Pull-Out Step with 9" Drop/Rise at 24" width, # LC432696. They measure 24" wide for the step but the overall width is 27-1/2" please... view full answer...
The Dexter 010-036-00 grease seal you have is a double lip grease seal with a 2.25" inner diameter. The correct replacement seal is the Grease Seal 10-36 - Quantity 1 # GS-2250DL.
This is also a double lip seal and a direct replacement for your current seals. view full answer...
According to Valterrra, if your # TC1372 waste valves are fully closing, but are still leaking you'll want to replace the seals. You'll need both the 3 inch seal kit, part # T1003-9VP and the 1-1/2 inch seal kit, part # T1001-9VP view full answer...
I was able to confirm that you've got a Lippert 1621 pinbox on your 2021 Cougar Half-Ton 24RDS, so the Reese Goose Box 20,000 lbs # RP85FR you were looking at is exactly what you're looking for. This will be a good replacement for your 15.5k RotoFlex pin box. view full answer...
