2003 Hummer H2 Performance Chip Tuners

The towing capacity of the 2003 Chevrolet Avalanche 1500 with 5.3L V8 and 4.10 rear axle is 8100-lbs. For a 7600-lb GVWR travel trailer the resulting 500-lb safety margin is adequate/low-ish. With a trailer that weighs substantially more than the tow…

Hey Robert, thanks for reaching out, and good question. When an air bag kit states "not compatible with in-bed hitch" that refers to both factory puck systems and aftermarket 5th wheel or gooseneck hitches. Both use similar frame brackets…

Hi Jeff, The K-Source Snap & Zap Custom Towing Mirrors part #KS69NQ will work with your Lariat mirrors while allowing you to retain the use of the camera and side lights! These mirrors are specifically designed to match the contours of the side…

Hey Michael! The 2026 Kia Sportage Hybrid has the 12V battery integrated into the main battery so you won't be making a connection there. What you need to do is run the #C59236 hot lead to the 12V positive jump terminal under the hood. Everything…

Good morning Howard! To replace your Heartland Pioneers ducted AC, I recommend the Furrion Chill Cube RV AC w Air Distribution Box item #FR69TD in white or item #FR49TD in black. These are complete systems with the 18,000 btu Chill Cube AC, an air…

Hey Robert, yes the Superchips Flashcal #SU67SR that fits your 2025 Ford Bronco does have start stop eliminator. So you won't have to worry about the engine shutting off when you come to a stop.

Hello David, Thanks so much for reaching out! For your 2026 Ford F-350 diesel dually, you will want the EcoHitch Hidden Front Mount Trailer Hitch Receiver - Custom Fit - 2" #EH54QR. This is the only front mount option we offer that is confirmed…

Hey Andrew! Yes, Furrion does have a Chill Cube model with a heat pump. This was actually just released for aftermarket sale. You will need a complete system to make the switch, new R32 units aren't backwards compatible with old R410A systems.…

Hey Lexie, the closest thing we have is the #BA65FR. This fits cutouts that are 5-1/4" wide x 4-1/2" tall. The little bit of extra height on your cutout won't be a problem since the face is 5-1/2" tall and would cover the opening.…

Hey Alex. From the information I can find online it does look like your 2011 Keystone Cougar 318SAB does come prepped for a second AC unit. The bedroom roof vent should be reinforced and pre-wired for a 13.5k or 15k BTU unit. To check if your trailer…

Hey Rick, yes you can just swap out the shank that you have now for one that is designed for a 2-1/2 inch hitch like the Blue Ox part #BXW4028. You probably already know this but you'll most likely need different spring bar tension on the new…
