The Jeep JK's thin sheetmetal fenders and stock plastic flares are among the most vulnerable body components when traversing the trail. The Poison Spyder JK Front Crusher Flare™ kit improves both the aesthetics and durability of your Jeep during your off road adventures. Poison Spyder Standard Width JK Crusher Flares™ provide tire coverage similar to the factory flares, with the added advantage of a better approach angle and outer tire clearance. Aluminum Crusher Flares™ are the perfect balance between strength and light weight, at less than half the weight of the steel Crusher Flares™ This product ships as bare aluminum—it will need to be painted or powder coated prior to final installation. We do not offer a powder coat option for this item.
Aluminum JK Crusher Flares™ are constructed using 1.5" X .188" wall annealed aluminum structural tubing as the outer "rub rail". This .188" wall tubing is thicker than the .120" wall tubing used in our steel Crusher Flares, to provide better resistance to crushing, kinking, and bending than competitors' aluminum flares made with .120" wall aluminum tubing. The foundation of the Crusher Flare is a CNC laser cut, 3/16" thick aluminum mounting plate, precision brake-formed to conform to the subtle curves of the JK's body panels. Mounting holes are countersunk for the use of flat-head stainless steel mounting hardware. The top plate is CNC laser cut 1/8" aluminum plate, which is hand formed around the curves of the Crusher Flare for a factory appearance that matches the JK's organic body lines better than any other aftermarket metal flare available. NOTE: Aluminum JK Crusher Flares DO NOT include a laser-etched Spyder logo along the lower edge. That feature is included on steel versions only. Photos in the gallery that depict the laser-etched Spyder are of the steel version of the Crusher Flare.
Exclusive Inner Brace Set
Every set of Poison Spyder JK Crusher Flares™ comes with a set of inner braces that tie the Crusher Flare in to the sturdier, heavier-gauge steel of the JK's inner body tub structure. Competitors' JK Flare products simply bolt directly to the outer layer of the JK's body sheetmetal. But as any JK owner knows, the exterior sheetmetal is very thin and flexible. Simply bolting a heavy duty fender directly to the exterior sheetmetal without the inner bracing is a disaster waiting to happen. Regardless of how sturdy the flare is built, upon contact with rocks, trees, etc., it will simply push in and deform the flimsy sheetmetal it is bolted to, possibly causing expensive and unsightly damage. The Inner Brace Set that comes with Poison Spyder Crusher Flares™ effectively bypasses the outer sheetmetal, instead transferring those forces to the much stronger inner structure of the Jeep. That's why we've been able to demonstrate the strength of our flare attachment system by parking another Jeep on top of the Crusher Flare™! These Inner Braces are CNC laser cut, brake-formed for a great fit and simple installation.
Rubber Liners Included
JK Front Crusher Flares™ come with high quality rubber liners to place between the Crusher Flare and the Jeep's body sheetmetal during installation. The rubber liners provide help protect your Jeep's exterior paint, where the flare contacts it. It also helps even out the contact area of the Crusher Flare, absorbing any small bumps or imperfections between the mated surfaces. The rubber liner also helps keep moisture, dirt and debris from collecting between the Crusher Flare and the Jeep's body. These liners are cut from premium EPDM rubber.
Retain Factory Wheel Wells
When installing Poison Spyder JK Front Crusher Flares™ you have the option of retaining the factory wheel well liner to protect the engine from trail and road debris. Retaining the wheel well also helps to conceal the Inner Braces to complete a clean and finished appearance. Some trimming of the plastic wheel well is required, but the kit comes with hardware and mounting brackets to re-install the trimmed wheel well.
Provisions for LED Marker Lamps
The JK Front Crusher Flare™ kit comes standard with mounting provisions to replace the factory side marker with a high intensity 3/4" round LED marker light. The addition of the LED provides a more modern and refined look that complements the function and style of the Crusher Flare™.
Steel or Aluminum?
Not sure whether to choose steel or aluminum for your Crusher Flares? Aluminum is lighter in weight, so might be the best choice for those looking to save weight on their heavy JK's in order to improve fuel mileage and gain an advantage off-road. However, when wheeling with aluminum flares it is up to the driver to use more care and finesse, as the aluminum components are not going to be able to withstand the same direct impacts that steel can. The outer tube on our aluminum Crusher Flares is beefy .188" wall thickness. Compared to our steel Crusher Flares which use .120" wall DOM steel tubing. The thicker tube wall recoups some of the strength lost by going to aluminum, however the steel versions will still be stronger in a direct impact with the rocks. For reference, a steel JK Front Crusher Flare weighs 31.6 lbs (not including hardware), while an aluminum one weighs only 11.8 lbs. Which is best for you will depend on your particular intended use of the Jeep, driving style and other factors.
