Edge Products puts a 5/7-drop on their 08 GMC Sierra for the SEMA show!

Edge Products

Edge Products Company develops and manufactures performance modules and programmers that enhance engine performance. What gives Edge –“the Edge”- in performance is their modules and programmers unique ability to monitor performance. Edge products can display multiple engine parameters right in the cab. Real time performance monitoring. When they decided to use a brand new 2008 GMC Sierra to show off their very cool hardware at the 2008 SEMA Show they called DJM Suspension for help setting up the Sierra with a high performance lowering suspension that complements their performance modules. They choose a CALMAX 5/7 drop for project SEMA Sierra.

Edge Sierra


First this project Sierra was fitted with the Edge Evolution programmer for gas powered GM trucks and SUVs. The Evolution programmer adds four levels of performance, refreshes the factory looking display in seconds as power levels change, works as a scan tool, and you can update the Evolution over the internet in seconds. For more info and specifications click here or go to www.edgeproducts.com.  This wolf in sheep’s clothing was dropped off at ALL PRO AUTO and OFF ROAD in Westhaven Utah to see if they could make it look more like the wolf it really is.


Calmax Suspension systems by DJM are considered the best complete, lowering suspensions by most who care about lowering, and the reason Edge Products wanted their Sierra to have one. The pictures that follow show the process as All Pro Auto installs the DJM 5/7-drop kit. DJM designed this Calmax kit with both upper and lower control arms that give the Sierra a 5 inch front drop that was aligned to factory specs when completed. The Calmax arms installed on project SEMA Sierra sport urethane pivot bushings with twin tube sleeves. What were talking about here is optimizing performance. The Edge Evolution adds horsepower and torque, the Calmax arms don’t waste any of it by allowing the pivot points in the suspension to deflect (squish) during acceleration, deceleration, cornering. Rubber bushings used by the factory will actually change shape (squish) under stress (cornering, braking, etc.). The urethane used by DJM practically eliminates this problem. When the rubber changes shape, your control arms actually move out of alignment, lets say during hard cornering, giving you less control when you need it most.  You still have your factory strut (spring & shock) with the full measure of travel designed by GM. You get all this performance with a smooth factory ride. What a combo! Click here to find out more about Calmax Control Arms. The seven-inch rear kit is a simple and sturdy installation. Using DJM’s exclusive axle brackets, spring plates and massive u-bolts you simply move the axle from beneath the leaf spring to on top! Follow the instructions your done, that’s it!
