1999 GMC Performance Chip Tuners

The difference between the Class II and Class III hitches has to do with their Gross Trailer Weight (GTW), their Tongue Weight (TW), and their Hitch Receiver Size. Class II trailer hitch receivers have a 1-1/4 inch receiver and can be rated up to…

For your Edge Evo HT 36030, I recommend using the same setting as you would for any of the tuners when hauling a load. I recommend using the "Tow" setting for light load tow.

A 4-Way trailer connector has the basic lighting functions only; running lights, left turn signal and brake lights, right turn signal and brake lights, and ground. A 7-Way has these functions and a 12 volt circuit, a circuit for electric trailer…

I checked out the installation instructions for the EvoHT2 Tuner, part #EP36040 and found that on page 18 it is explained how to return the engine tuning to stock. From the main menu you will need to select 'Tune Vehicle'. Then select…

Your Edge EvoHT2 #EP36040 is also a confirmed fit for your 2001 Dodge Cummins. This controller is only able to be used on one vehicle at a time, so setting that tuned vehicle back to stock will allow it to be used on another vehicle. Since he said he…

I have a solution for you, but the Edge Module part #EZD1000A is not a fit for the 2005 Dodge Ram Cummins. Instead you would want the #EP36040 if you have the 325 horsepower Cummins or the part #EP30204 for if you have the Common Rail 24 valve that…

Chevy stopped using a port to plug in a brake controller after the 2006 model year. The tow package wires to install a brake controller are still present up under the dash, to the left of the steering column, held together with a white tag. The wires…

Hey Matt! What you're looking for is 5th Wheel/Gooseneck wiring. The Curt #C56070 plugs in-line with the back of your factory 7-way allowing you to run a separate 7-way connector up to the truck bed. Are you looking for tie-downs as well? I…

Not that one Scott, but I have one that will. The UWS Truck Bed Fender Well Toolbox item #UWS01624 is too tall at 23-1/4". To keep below your bedsides you'll need to use the DeeZee Specialty Series Passenger's-Side Wheel Well Tool Box…

The big difference between the two SuperChips programmers you mentioned of #SU1845 and #SU4845 is that the #SU4845 has been approved for use in the state of California. Aside from that it's the exact same programmer so you'd need to pick…

The OEM prep package consists of 4 "pucks" in the bed of the truck that will allow you to drop in puck style hitches for easy installation and removal, that gives you a completely clear bed when not in use. The B&W Companion OEM 5th…

Hey Darrel, we actually have exactly what you are looking for with the part #TRU52FR which is for a 7k axle and is 25-1/4 inch from eye to eye. This is also a 6 leaf spring as well. The spring you referenced would be too short.
