Rough Country 1.75 Jeep Wrangler JK Suspension Review

Posted in How To: Suspension Brakes on August 3, 2016

There’s no question that the ’07-present Jeep JK Wrangler Rubicon is one of the most dynamic off-road vehicles ever produced right out of the box. In fact, for many Rubicon owners, it can meet the majority of their off-road needs with very little modification. However, we understand the desire to lift the Wrangler, as it can aid off-road performance, as well as help your JK stand out from the pack. The challenge for many is picking the right suspension lift that won’t completely sap the practicality of the Jeep.

We dealt with this challenge recently with our ’13 Wrangler Unlimited Rubicon. With selectable lockers and a factory sway bar discontent, most of the commonplace off-road necessities were covered. We were simply looking to put on slightly larger tires with a very modest amount of lift. Despite the seemingly endless array of suspension lift kits, we picked one that was a homerun on both the need and budget field of play. In fact, at $220, the Rough Country Suspension 1 3/4-inch suspension lift seems like one of the best bang-for-your-buck upgrades we’ve installed. Because the Rough Country kit uses coil spacers and new shock absorbers, it was something we (and you) easily installed in our home garage. So, how did it all work? Read on to find out.

You don’t need any special tools to install the 1 3/4-inch Rough Country lift. We did one side at a time using jack stands to support the frame and a floor jack to raise and lower the axle.
Polyurethane coil spacers provide the 1 3/4-inch lift. These sit in the place of the stock coil isolators at the top of the coil bucket. Because the smooth-riding stock coil springs are not replaced, the well-engineered factory coil rate and ride quality of the Jeep are retained.
One of the other aspects that drew us to the budget-friendly lift kit was the fact that it came with four Premium N2.0 Rough Country shocks. The shocks offer a chromed and hardened 9/16-inch piston rod and vehicle-specific valving for durability and a controlled ride.
To save a little money and retain our Jeep’s 17-inch Rubicon wheels, we opted for a set of Rough Country’s 1 1/2-inch wheel spacers. Made from 6061-T6 aluminum, they provide the additional backspacing needed to keep our new treads from contacting the Jeep’s frame and suspension components.
Speaking of tires, it wouldn’t be much of a lift without a new set of treads. While we could have gone bigger if we wanted to do a little fender trimming, we like the footprint our new 33x12.50R17 General Grabber AT2 tires provide. This all-terrain tire’s design offers an extremely wide five-row tread pattern with plenty of biting edges and is a great balance of quiet on-road performance and potent trail prowess.


In The Dirt
As we’ve said before, when compared to other “off-road” vehicles, it’s hard to beat the factory performance of a JK Wrangler Rubicon. The added height and footprint of the 33x12.50 tire absolutely makes a positive difference off-road, and the lower we ran the air pressure, the better the tires worked. With our automatic transmission, we wish our Jeep would have been equipped with the optional 4.10 gears instead of the 3.73s. We haven’t noticed a major difference in fuel economy with the 33s aboard but did notice a bit of the acceleration is gone. Overall, we’re extremely happy with the on- and off-road ride quality and, dare we say, practical sizing of the overall setup.
