***This kit includes 60" long bars for Regular Cab Long Bed, Extended Cab Short Bed and Crew Cab Short Bed Models***

***This kit is for 2011-2019 GM HD Trucks***

If you have Extended Cab Long Bed or Crew Cab Long Bed truck use part number WCF100853. If you have a Lift Kit and your U-Bolts face up instead of down like factory, use Traction Bar Kit WCF100855.

If you have a Lift Kit and your REAR lift Block is taller than 5" or your total lift height is 6" or greater, use part number WCF100853. If your truck is on a big lift, please measure from your axle mounting point to your frame mounting point to ensure the bar length will work properly for your application before placing your order.

Built in house at WCFab carrying a LIFETIME WARRANTY against bending or breaking (to original purchaser). Traction bars are a necessary upgrade when increasing the horsepower on your diesel truck to prevent the axle from twisting which can lead to broken u-joints, driveshafts, and even twisted axle housings. Our traction bar brackets bolt on to the bottom of the axle tube via the axle u-bolts and weld to the frame on the front end. We use a high quality RockJock rebuild-able and grease-able “Johnny Joint” heim connection at the frame to allow for adjustment of torsion on the axle or if you raise/lower the rear of your truck. At the axle connection we use a heavy duty Poly Urethane Bushing for decreased noise and vibration which is common complaint if a solid heim is used on both ends. Grade 8 hardware connects the bars to the mounts on the frame and axle. We complete our traction bar kit with our professional in house powder coat process in your color choice and comes standard with a epoxy Primer base coat before the final color which increases corrosion resistance by more than ten times compared to just your standard powder single coat application.

Cognito forged steel Torsion Bar Adjuster Key Kit for 2011-2019 Chevrolet and GMC 2500HD / 3500HD 2WD/4WD trucks. Torsion bar keys are used to set the ride height of the front of the truck and are commonly used in leveling kits, and it is important to set the height appropriately as to leave ample suspension droop travel to maintain a good ride quality. There are several different torsion bar spring rates that GM made and put in these trucks, the rate depending on the model and features of the truck. Some trucks that have a higher spring rate may not need aftermarket torsion bar adjuster keys to obtain the maximum recommended ride height. This kit is only used in leveling kit applications as well as lifted applications when the higher setting of that particular lift kit range is desired like taking a 4" Cognito lift kit to the 6" setting.

Removing the OEM plastic lower bumper valance on the 2015-2019 Chevrolet Silverado 2500 / 3500 HD trucks is a proven method for improving ground clearance and fitting more aggressive wheel and tire combinations, but leaves an unattractive, gaping void in the lower middle section of the bumper.

To solve this issue on customer trucks getting suspension lifts at our shop, we've developed two Lower Valance Filler Panel options for trucks with and without tow hooks.

These heavy gauge aluminum panels finish off the lower center cutout in the bumper providing a more aggressive look to lifted or leveled trucks.

**NOTE: This Model is meant for use on trucks that have tow hooks installed in the front frame horn, the filler panel has windows to access the hooks.

Results in torque and power gains across the full operating rpm range, starting right off idle and marching to the shift point in each gear. Derringer is dyno calibrated to use multiple data inputs such as throttle position, rpm, vehicle speed, AFR, knock, coolant temperature, and EGT, just like your engine's ECM. It actively and safely optimizes calibrations in real-time thanks to its OBD-II connectivity. No competitive tuner does that.

Derringer has 6 levels, adjustable on-the-fly using the iDash. Level 6 produces best-in-class performance. Level 3 is designed for work use and has a great mid-range feel. When running Level 3 with a loaded truck and/or pulling a trailer, your on-ramp merging speeds and passing times are greatly improved.

The electronics are enclosed in a compact housing which is easily concealed and communicates with other Banks devices such as our iDash DataMonster, iDash SuperGauge, and PedalMonster throttle booster. The Derringer connects in line with your truck's engine sensors. But unlike other tuners, it also connects to the vehicle's OBD-II diagnostic bus.

ActiveSafety health monitoring circuitry keeps an eye on the vehicle and the module itself. It checks its health 100 times a second. If it detects an issue, the Derringer instantly bypasses itself, sets a device diagnostic code, and seamlessly returns the truck to stock power. Plus, Derringer's special coolant temp monitoring prevents power addition when the engine is too cold or overheated. The Derringer also auto-adjusts power if knock occurs due to bad fuel. Maximum safe power is all automatic with a Derringer — you just choose your preferred power level and enjoy the ride.

• Adds up to 61 hp and 112 lb-ft
• 6 power levels that can be changed on-the-fly via iDash. Each level adds approx 12 hp
• Simple plug-and-play installation with easy removal for dealer service
• Interfaces with OBD-II Port (On-Board Diagnostics) to communicate with vehicle's ECM
• Warranty friendly: no reflash required and no traces left in ECM
• Works while in cruise-control
• AutoRate tunes in realtime using vehicle diagnostics

US Patent #10,138,851 B2

This high flow fabricated aluminum intake pipe, intake horn, and air box enclosure with dry filter assembly replaces the restrictive plastic factory parts on your Duramax Diesel for improved engine performance and sound. All new design significantly increases airflow to your turbo producing improved horsepower and torque, quicker throttle response, and cooler intake temperatures by drawing cold air through the hood Ram Air duct and inner fender. Our all aluminum construction features large diameter 4" piping with smooth aerodynamic bends. This improves intake air velocity, volume, and provides a more aggressive engine and turbo sound during acceleration. The intake horn is over an inch larger than the OEM diameter and we experienced a 25HP Gain with our 3.5" Horn when used with a Max Effort Tune.

High quality hardware, silicone boot, seals, and stainless steel t-bolt clamps ensure optimum durability and ease of installation. Removable air box lid element allows for easy visual inspection and maintenance of your WCFab filter with included hydrophobic pre-filter cover, to help keep your MAF sensor, turbo, and engine airways contaminant free. The critical ram air duct seal has been moved to the bottom of the hood for a clean engine compartment appearance.

Full assembly finished in your choice of WCFab's signature custom powder coat colors for a look as unique as your truck.
