Why do we trust ?

Kryptonite builds heavy-duty steering and suspension components designed for hardworking trucks, whether you’re lifted, towing, or making serious power.
Why we recommend them:
- Stronger front end components
- Better stability under load
- Built for lifted and high-performance trucks
- American-made parts designed to last

Quick Tip: worn suspension and steering parts aren’t just annoying, they can become a serious safety issue if ignored.
If your truck feels loose, rough, or just not riding like it should, let’s get it checked out 🔧

Truck came in and we found metal inside the regulator. 🔧
Definitely not something you want to see.
To get this truck back reliable and protected from further damage, it’s getting:
New S&S Diesel Motorsport DCR conversion
Contamination kit
-New fuel lines & rails
-New injectors & injector lines
-OEM fuel filters
Complete clean-out with fresh components throughout
When metal starts moving through the fuel system, it can quickly take out injectors, pumps, and more. Catching it early can save you from a much bigger repair bill later on.
