Question:
The disc brake kit I ordered shows that it comes with a seal inner dia. of 2.250. I have a 7000lb AL-KO axle that from research shows a seal with a 2.125 inner dia. Is that possible? My order number was 122952026

Hello Robert, thanks for reaching out. The Hydrastar Disc Brake Kit # HSE7K-T1 does come with the 2.250" ID seal. If you are needing the 2.125" ID seals you can use the following:
- 10-10 Grease or Oil Double-Lip Seals - Qty 2 # RG06-090
Both seal sizes are used for 7,000 lb axles. The 2.250" is more common but both are definitely out there.

Hey Robert, did the 10-10 Grease or Oil Double-Lip Seals work out for your 7000lb AL-KO axle? I'm curious because it could help others in a similar situation.
