Rear Window Lift Springs
 
   Stainless Steel

2019/08/15  @  8,000 mi.
We have developed hood and trunk lift kits for other vehicles, so replacing the stock window springs with these more attractive and durable stainless steel ones was a no-brainer.  These springs are slightly shorter than stock, so the window won't hit overhead obstructions when opened in a garage.  They're also strong enough that they'll hold up in wind and last years beyond their OEM counterparts.

Engine mounts in modern vehicles are always a compromise between durability and mitigating NVH (noise, vibration, harshness).  Make them too soft, and they won't last through the warranty period; too hard, and car magazine reviewers complain.  Since 1997, we've been taking original equipment style mounts and filling the air gaps (and oil, in the case of hydromounts) with our own blend of polymer-fiber-reinforced polyurethane rubber.  Rather than wait for our own mounts to get all old and busted, we decided to tackle these early.  They'll hold up far longer than stock, but with much less vibration than solid metal mounts or hard plastic inserts we've seen available for other models.

The forums are loaded with JL owners complaining of rock chipped windshields, so adding a hood shield seems like some cheap insurance for the hood and hopefully the lower part of the windshield, where most rock damage seems to be popping up.  It's attractive, and not so tall you see a lot of it from the driver's seat.

Ti Oil Plug

With our first oil change coming due, it's time to pay attention to the little things.  In this case, we added a titanium oil plug.  Titanium is lightweight and won't rust.  The plug has an integral magnet to collect fine ferrous particles the filter might miss.  The hex is larger than the one on the stock oil plug, for a more solid grip.  The included aluminum sealing washer is reusable and easily replaced.  And lastly, drilled holes in the hex flats allow for attaching wire, which is done often on bikes and race cars for added security.  A little cheap insurance goes a long way!  We finished off the oil change with a K&N filter and Valvoline 5W30 synthetic, since we're just now coming up on summer and lots of towing miles in front of us.  We'll use the recommended 0W20 for winter driving.

Since our primary summer use for our JL is towing, we need to amp up the power in every way possible.  We start this process by boring out the original equipment throttle body from 74mm to 78mm.  At idle and part throttle, the difference is unnoticable, but under WOT, the engine is a little more awake than it would otherwise be.  This mod preps us for ramping up fuel flow in the future to match, too!  With a balanced increase in fuel and air flow, we can start looking at other power adders in the future.

License Plate Installation Kit

2019/04/01  @  3,000 mi.
Finding a place to mount the required front license plate on a Wrangler can be tough.  We didn't want it scraping obstacles, blocking airflow, or getting in the way of mounting locations for lights or a winch.  We managed to avoid all these problems, coming up with a solution that's aesthetically out-of-the-way, functional, durable, and street-legal. The unique design is a hinged front bracket, constructed from aluminum, with a polycarbonate backing plate.  It mounts under the bumper, and can swing fore and aft to minimize damage while off-roading.  And of course, we topped it off with anodized aluminum screws, and matching fasteners for the rear plate.

Since we're starting with a fairly bare-bones Sport model, the Jeep looks a bit naked in some ways.  No side steps, for example, and even the gas cap doesn't have a door in front of it.  To remedy this, we went straight to the Mopar catalog, and opted for the OEM part used on the upper models.  We selected black, to match the top, fenders, and other parts not in body color.  The door keeps out dirt and weather, and gives Creeper a little bit more of a finished look.

2019/02/01  @  1,000 mi.
In deciding what direction to start with modifying our new Wrangler, we get a jump-start by fixing minor engineering oversights, designed-in diagnostics issues (Secure Gateway Module), and the feature factory-engineered safety flaw of an engine that stalls out in traffic.  It didn't take us long to purchase and install the TazerJL from ZAutomotive.  The Tazer can automatically disable ESS, recalibrate the speedo for different tire sizes, turn on the backup camera with turn signals, and so much more!  We've only scratched the surface of what it can do, but having an engine that doesn't die at stoplights and reclaiming the ability to reset engine codes has already made it a worthwhile investment.  We paired it with an OBD splitter cable so it doesn't stick out into the footwell, and we don't need to unplug it to capture runtime data or run diagnostics.
