Everything You Need To Know About Ford's Most Popular SUV

For years the Ford Explorer was the bestselling SUV in the country, yet you rarely see them on the trails in numbers comparable to Jeep Cherokees or Toyota 4Runners. With production spanning two decades and high sales numbers, you can pick up a used Explorer for cheap and be out on the trails tomorrow... well, exploring. Cheesy puns aside, these Blue Oval SUVs offer good dimensions for wheeling along with potent engines and capable suspensions. There are a few pitfalls though, and you need to know what you are looking for.

First Gen (’91-’94)
The Explorer was designed as a replacement for the Bronco II, and it is a vast improvement in drivetrain strength over the BII. All first-gen Explorers came with a 4.0L OHV V-6 that made 155-160 hp and was backed by either a A4LD four-speed automatic or a Mazda-sourced M50D five-speed manual. Neither transmission is particularly strong, so plan to swap them out if you are shoehorning a V-8 in your Explorer. If you are looking at an Explorer with an A4LD, pull the dipstick and smell if the fluid is burnt. They get hot and can benefit from an auxiliary cooler like those offered by Flex-a-lite and B&M.

The transfer case is a BorgWarner 1354 chain-driven case with either a traditional lever or the electronically shifted “Touch Drive.” Both use fixed yokes and can be shifted from 2-Hi to 4-Hi on the fly. The electronically shifted case can easily be swapped with the more desirable manually shifted case with just a few parts from a donor Explorer. The floor plate with shifter boot will bolt right in with no transmission tunnel modifications.

The Explorer was available in two-door or four-door models, with wheelbases of 102 and 112 inches, respectively. Note that they were also available in 2WD, so make sure there is a transfer case when you go on a test drive!

The front suspension on first-gen Explorers uses Twin-Traction Beams (TTB) with a high-pinion aluminum Dana 35 front differential. The radius arms, coil springs, and traditional steering box all lend themselves to relatively easy solid axle swaps. If you want to stick with the TTB there are suspension offerings from James Duff, Skyjacker, Superlift, and more. Out back the 31-spline, drum-braked Ford 8.8 axle is plenty strong and uses simple leaf springs under the axle. 235/75R15 tires came stock, and 31s will fit with just a small suspension or body lift.

Explorer Quick Facts
First Gen (’91-’94)
• 4.0L OHV V-6
• 4-speed auto or 5-speed manual
• TTB front suspension with high-pinion Dana 35 diff
• Leaf spring rear with Ford 8.8 diff
• 32.6˚ approach angle (4-door)
• 22.3 ˚ departure angle (4-door)
• 15/19 mpg (automatic transmission)
• 19.3-gal fuel capacity (4-door)
• 34.2-ft turning radius (4-door)

Second Gen (’95-’01)
The second generation of Explorer saw the TTB front suspension replaced with more conventional IFS with torsion bars, but there are still plenty of reasons to consider this model. They did not grow in size at all and still fit on most trails, plus you can get one from the factory with a 5.0L V-8. Basically every speed part available for Mustangs fits the 5.0L in Explorers.

The 5.0L was an option starting in the ’96 and came backed by a 4R70W four-speed automatic transmission and an all-wheel-drive BorgWarner 4405 transfer case. The AWD transfer case does not have a low range; however, a common swap is to a manually shifted BW4406 case from a ’97-’03 Ford F-150. That not only gives you a low range but also drops the AWD function to potentially increase your mileage. The forum Serious Explorations (www.explorerforum.com) has step-by-step instructions on how to perform this swap.

In the ’97 model a SOHC 4.0L V-6 was introduced that makes 205 hp and is mated to a 5R55E five-speed automatic. Both the V-6 and V-8 engines return similar mileage.

Wheelbases are unchanged from the first-gen Explorer. The rear end still uses leaf springs and a sturdy 8.8 differential. Disc brakes became standard in the ’95 model year. The IFS does limit lift options, but Superlift makes a 4-inch lift specifically for this model and most Ranger front suspension kits will fit the Explorer. Longer shackles and cranked front torsion bars are popular and inexpensive to gain 1-2 inches of extra height. If you want to make the most of that 5.0L V-8 and go fast, Dixon Brothers make a long-travel IFS kit with 14-inches of wheel travel.

Second Gen (’95-’01)
• 4.0L OHV V-6, 4.0L SOHC V-6, or 5.0L V-8
• 4-speed auto, 5-speed auto, or 5-speed manual
• Torsion bar IFS with high-pinion Dana 35 diff
• Leaf spring rear with Ford 8.8 diff
• 32.1˚ approach angle (4-door)
• 23.9˚ departure Angle (4-door)
• 14/18 mpg (V-8 with automatic)
• 21-gal fuel capacity (4-door)
• 38.4-ft turning radius (4-door)

Third and Fourth Gens (’02-’10)
For 2002 the Explorer lost all commonality with the Ranger pickup and went to fully independent suspension front and rear, though it was still body-on-chassis construction with a true frame. While the SUV market in general has been sacrificing capability for comfort, the Explorer in particular received bad publicity related to the rollovers of the previous models. This influenced the switch to independent suspension and also had a large influence on the tire pressure monitoring systems (TPMS) that are standard on all new vehicles. The third and fourth generations of Explorers are difficult to modify for trail duty and have limited aftermarket support. Rancho does make a 2-inch QuickLift that allows fitment of 31-inch-tall tires.

Third Gen (’02-’05)
• 4.0L SOHC V-6 or 4.6L V-8
• 5-speed automatic or 5-speed manual
• Coilover IFS with Dana 30 diff
• Coilover IRS with Ford 8.8 diff
• 31˚ approach angle (4-door)
• 24.5˚ departure angle (4-door)
• 14/19 mpg (V-8 with automatic)
• 22.5-gal fuel capacity (4-door)
• 36.7-ft turning radius (4-door)

Fifth Gen (’11 and later)
The fifth-gen Explorers use unibody construction and are available in either front-wheel drive or AWD, with no low-range offered. A sad end to a vehicle that originally possessed so much off-road capabilities.

Aftermarket Support
The aftermarket support for Explorers is sparse compared to Cherokees and Wranglers, but it does exist. The Explorer uses the same 5-on-41⁄2 bolt pattern as YJs and XJs, so aftermarket wheels for these vehicles will fit on Explorers. For lower gears and lockers you have plenty of options, and D&D Machine even makes a doubler kit to put the reduction box from a BW1350 in front of the factory BW1354 transfer case. RLC Fabrication has the widest selection of armor with skidplates, front winch bumpers, and rear bumpers with tire carriers for Explorers, but James Duff makes Explorer front bumpers as well.
