2004 Jeep Wrangler Rubicon - 4x Forum

Calling All CarsQ: Being that there's an apparent need for CB radios in Jeeps, I would like to see an article about installation methods, particularly in Jeep TJs. I'd also like some information about available CB brands and what features are offered. The only clean installs I've seen in TJs used a Tuffy overhead console, but I'm sure others exist. Thank you.Bob TravisHollister, California

A: Bob, We've seen a variety of CB radio mounting methods over the years, including many in Jeep TJs. While some did in fact use a Tuffy overhead console, others had fashioned custom mounts off the rollcage spreader bars, or mounted the radio atop the dash tray above the A/C vents. In addition to its overhead console, Tuffy Security Products [(800) 348-8339, www.tuffyproducts.com] offers its deluxe stereo console for Jeep TJs and other vehicles that can be outfitted with a stereo or CB radio. Turbo City [(714) 639-4933, www.turbocity.com] also produces an overhead CB mount for Jeep YJs and TJs, which fits above the rearview mirror and attaches to the windshield frame. As far as CB radios go, we've yet to test a great degree of those available. We have, however, used a few of the units available from Cobra Electronics [(773) 889-3087, www.cobraelectronics.com] to good effect. Other sources for a variety of CB brands are Radio Shack (www.radioshack.com) and Midland Consumer Radio [(816) 241-8500, www.midland radio.com]. Look for more information on CBs and related products in an upcoming issue. Thanks for writing.

Oil-Cooling IdeasQ: Having owned various Jeep Wranglers and Cherokees over the past 14 years, I appreciate the insight your magazine provides. My latest purchase is an '04 Wrangler Rubicon, and I'm hoping I can get a reply to a nagging question. With a heavy-duty this or that available for just about every component on a Jeep, one item I would like to install but have never come across is an engine-oil cooler. While a few alleged universal products exist, I'm quite hesitant about installing something that has not been tested and proven to work without damaging side effects. Do you know of any OEM, Mopar, or other aftermarket engine-oil coolers that are specific to a Wrangler Rubicon?Roy BalazsAurora, Illinois

A: Roy, Since the Wrangler Rubicon uses the same 4.0L I-6 used in the standard-model Wranglers, there isn't really a calling for Rubicon-specific engine items. Although a few variances exist between model-year vehicles, the overall engine is essentially the same and will accept most products designed for use on the 4.0L engine. Concerning engine-oil coolers for this particular engine, we weren't able to locate any kits made specifically for the Rubicon or 4.0L engine. You're right that a number of universal kits are available, though many appeared to be better suited to larger-displacement mills. We did come across two kits, however, that are indicated to be applicable to Jeeps with the 4.0L. Flex-A-Lite [(800) 851-1510, www.flex-a-lite.com] and Perma-Cool [(909) 390-1550, www.perma-cool.com] both offer universal engine-cooler kits designed to maintain engine operating temperatures. Another item of interest that pertains to the topic is the 4.0L high-volume oil pump available from Mopar Performance Parts (www.mopar.com). This pump uses a larger rotor to increase fluid capacity by 25 percent and is designed to fit 4.0L and 4.2L engines. Good luck.

Engine and Axle UpgradesQ: In January 2004, my unit A-Battery, 3/82 FA 1st Cavalry Division out of Fort Hood, Texas, deployed to Iraq. I now have quite a bit of time to think about all the great things I want to do to my Jeep Wrangler. I was hoping you could help me find some parts to beef up the 2.5L engine and what I believe to be Dana 35 axles. Thanks for your help.Pfc. Tylor GaspardBaghdad, Iraq

A: Tylor, First off, many thanks for enduring a job that many couldn't fathom attempting. While being away from family and friends is sure to be difficult, we can only imagine that being away from your Jeep is troublesome as well. Since you have the time to daydream, though, we'll offer a few suggestions as to what modifications we'd carry out on a similarly equipped rig. As far as beefing up the 2.5L four-cylinder, an air-induction kit and throttle-body spacer are good starting points. A free-flowing exhaust system would also prove beneficial, as would a header. A new set of plugs and ignition wires couldn't hurt, either. Check out AEM [(310) 484-2322, www.aempower.com] and Airaid [(888) 694-1840, www.airaid.com] for air-induction kits and TB spacers. Banks Power [(800) 398-0798, www.bankspower.com] offers header and exhaust systems. Getting into the axles, think about a Super 30 and Super 35 kit from Superior Axle & Gear [(888) 522-2953, www.superioraxle.com]. Both kits upgrade the stock axleshafts to Superior's alloy units and provide a good deal more strength. The final steps we'd recommend are to replace the vacuum-actuated axle-disconnect system with a 4x4 Posi-Lock manual axle disconnect and install a set of locking hubs. Collins Bros. Jeep [(800) 699-5337, www.collinsbrosjeep.com] offers both the 4x4 Posi-Lock and locking hubs. Best of luck to you, Tylor. We hope you make it back to your Jeep and your favorite trails before too long.
