Skid Plates
- /shared/2013/wrangler/capability/offroad/primary/10_j_w2d_cap_off_skidplates_prm.jpg
Skid plates protect the underside of your vehicle from off-road rocks and on-road debris. Front suspension and drivetrain plates are constructed of 3-mm thick stamped steel, and include: an automatic transmission skid bar (not shown) that protects the transmission oil pan; a transfer case skid plate and a fuel tank skid plate.

Solid Front & Rear Axles
- /shared/2013/wrangler/capability/offroad/primary/10_j_w2d_cap_off_solidfrontaxle_prm.jpg
Wrangler's solid axles feature added durability and articulation, thanks to a large driveshaft, stiff housing, larger pinion bearing and above-center pinion mounting. Tough axles and drivetrain. To increase structural stiffness and effectively double the sealing capability, the NV241 GII and NV241 OR transfer cases use 18 bolts.

Suspension
- /shared/2013/wrangler/capability/offroad/primary/10_j_w2d_cap_off_suspension_prm.jpg
Solid axles with locating arms, coil springs, track / stabilizer bars, front steering damper and high-pressure gas-charged shock absorbers toughen this suspension.

Driveshaft
- /shared/2013/wrangler/capability/offroad/primary/10_j_w2d_cap_off_driveshafts_prm.jpg
Wrangler’s axle shafts appropriately handle the high torque (using a large 1250 series joint). Driveshafts are harmonically quieter, thanks to increased bending stiffness and precise balancing.

- Crawl Ratios

Rubicon has an incredible 73.3:1 crawl ratio, allowing for a controlled 0.5 mph cruise up or down the rocks. High crawl ratios keep you slow for more control on the rock. The crawl ratio is the combined first gear x low range x axle ratio. The higher the number, the slower the vehicle will go. And driving slowly is the key to successful off-road driving, especially over rocks and rugged terrain. You’ll be able to see what you are driving over and tiptoe over obstacles with controlled authority.
- Tubular Rock Rails

Mopar® rock rails are constructed of heavy gauge steel tubing to take on the toughest trails. These rock rails are fully functional and provide added lower bodyside protection when off-roading. Rock rails have passed stringent corrosion and appearance testing for long life. For more on this Jeep accessory by Mopar, visit mopar.com.
- TRAC-LOK® DIFFERENTIAL

The Trac-Lok® rear differential is available on select Wrangler Sport and Sahara models. It’s a torque-sensitive mechanical unit that works to maintain traction in slippery or rough conditions. Trac-Lok automatically distributes the available rear torque to the rear wheel that provides the most traction, thus helping to reduce wheel spin caused by lack of traction in the other rear wheel.
