Product Details
Alpine IR™ Front and Rear Adjustable IR FlexArm Kit for 2.0"-4.0" Lifted Vehicles (1415611) by TeraFlex®. Quantity: 8 per Pack. Lift your Jeep. Lift it for several good reasons, all of which will make it more capable in off-road situations. Lift it to install larger diameter tires by making more room in the wheel wells. Lift it to improve ground clearance for climbing over stumps and rocks. And lift it for the appearance and the commanding driving position, even on the street.

Lifting your Jeep more than an inch or so can lead to a number of issues that, fortunately, are relatively simple to address. And those new parts to fix these issues can also be parts that are sturdier and more long-lasting than the stock parts you're replacing – and that's always a good thing. Off-roading, by its very nature is harder on your vehicle than grocery-getting or commuting, so upgrading is never a bad idea. Don't forget you'll need to add some provision for helping out things like the brake lines, shift linkage and to compensate for steeper driveshaft angularity.
TeraFlex® has been professionally involved with Jeeps since the 1950s and that experience taught them how to make them perform their best. TeraFlex was started in the fall of 1996 to meet the needs of the growing market for heavy duty off road equipment and suspension enhancements. And they've maintained a dominant hold on the market since then. TeraFlex was the first aftermarket manufacturer with a suspension system for the TJ Wrangler, and is still the only aftermarket company to offer a solution for the venerable 231 transfer cases low range gearing. In 2001, the entire off road industry was stunned at the CRD60 - an off-road-specific high-pinion 60 differential that took innovation to a new level, reinforcing their position in the industry.
