Question:

I have a 2020 f250 with 3 rear leafs and no overload spring. This product description says: If your vehicle is equipped with a brake fluid proportioning valve this constant rate spring is not recommended. Only progressive rate helper springs should be used. How could I determine if this is the case on my truck? Thanks.

Hey Josh. The brake fluid proportioning valve on your 2020 Ford F-250 will be located underneath your hood near the master cylinder and brake lines behind or around the air intake. I attached a picture below so you know what to look for.

If you don't have it you're good to go on the Hellwig Load Pro 35 Heavy Duty Helper Springs with Custom Mounting Kit item # HE44TR. If you do you'll need the Hellwig Load Pro 25 Progressive Helper Springs item # HE94TR.

Are you pulling a trailer or hauling a heavy load in your truck bed?
