Kryptonite Ball Joints are built better, here in the USA and have a LIFETIME WARRANTY.

Even if your truck is only leveled, extended CV Axles with a LIFETIME WARRANTY are a good choice.

Keep your transmission happy with a service package made specifically for Allison’s.

An upgraded wheel bearing with a 3-Year UNLIMITED MILEAGE WARRANTY is a no brainer for your truck. We highly recommend adding 4 new Spindle Bolts.

The most notorious weak link on your front end are the Tie Rods. This set from DMAX XD is much stronger than stock and has a 3-Year UNLIMITED MILEAGE WARRANTY.

Fuel components like your injectors and injection pump are not cheap. Keep them protected with an OEM quality AC Delco Fuel Filter.

Made of T6 6061 Aluminum and anodized green, we designed a fuel cap the way GM should have. *NEW LOCKABLE OPTION AVAILABLE*

Engineered & manufactured in the USA to increase ride quality, withstand abuse, and correct geometry, Kryptonite Upper Control Arms just make sense. The LIFETIME WARRANTY is just icing on the cake. We highly recommend adding the Alignment Pins & Cam Centric Bolts.

Bilstein 5100’s are hands down the best bang for the buck and will help smooth out the ride on your Duramax.
