Purchased a used JKU (my first Jeep) with the plan to keep it stock with the exceptions of addressing known JKU issues and beefing it up for light off-road use. After researching, decided Teraflex provided the best bang for the buck. I ordered the front and rear Teraflex track bars. I was impressed with the weight of the track bars, particularly after removing the stock track bars and comparing side by side. The Teraflex bars are substantially heavier. Installation for both bars took about two hours and I used the grade 8 9/16"" bolt kits to replace the OEM bolts. I found the handling has improved with a significant reduction of my Jeep wanting to wander on unpaved and paved roads. I strongly recommend the Teraflex bars to any Jeep owner wanting to beef up the undercarriage and improve the ride of their Jeep.
