The only complaint I have is that the bolts aren't long enough. Instead of crying and sending it back. I just bought new ones to fit. Seem to run fine. Didn't change anything nor the fuel milage

Holes in the billet housing were too small to fit onto the fuel bowl. Installed the seat and spring with new gasket using the OEM housing. Wish the housing would have fit - easy way for anyone to know the truck has the blue spring kit in the future.

Good online experience, poor product fitment.

The kit fit the assembly like an original. It did not fix the problem that I was having, but it will make the engine run better when we get the other problem fixed.

Why Trust Verified Reviews?
Verified Reviews are real, authentic reviews collected from actual paying customers, using Shopper Approved's Verified Review Platform. When reviews are Verified by Shopper Approved, you know that you can trust them to make better buying decisions.
Unverified Reviews on the other hand, are reviews collected by Open Review platforms that allow anyone to leave a review, without any validation or proof of purchase. Unfortunately, most reviews you read online are Unverified Reviews, and can't be trusted.
As a consumer, here's how you can tell the difference:
Verified Reviews from Verified Review Platforms like Shopper Approved, have much higher review counts and higher overall Star ratings, because they attempt to collect reviews from every single paying customer.
Unverified Reviews from Open Review Platforms, tend to have much lower review counts and more negative Star ratings, because people with bad experiences are primarily those who leave reviews. This often creates a misleading, inaccurate portrayal of a companies true reputation.
So, when searching for Verified Reviews, look for the name you know you can trust. Shopper Approved.
