JKS Manufacturing


Last month JKS Manufacturing released the Advanced Geometry Upgrade Kits for Jeep Wrangler JK. Once installed the kit corrects steering and suspension geometry on 2-5'' lifted 2007-2015 Jeep Wrangler/Wrangler Unlimited JKs for improve handling and overall driveability. One of the keys to correcting the steering geometry involves flipping the drag link mount on the steering arm to level out the operating angle which requires drilling out the factory JK steering knuckles to 7/8''. JKS now offers a versitile tool to make the task much easier with the JKS.1699 7/8'' step drill bit. Much more affordable than sourcing an expensive 7/8” drill bit, this hardened high-speed steel step bit has a titanium nitride coating that won’t bind against the factory tapered hole and doesn’t require multiple bit changes to progressively enlarge the hole.  The stepped design also makes it very easy to keep the bit square to the hole and eliminates the possibility to bit wander and risk an ob-round hole.

Along with its effectiveness to drill out steering knuckles this step drill serves is a great tool to have in your shop or trail side tool kit.  Capable of drilling holes from 3/16” to 7/8” in 1/16” increments, this step bit is self-piloting so all you need is a center punch to locate your hole.  The step bit is made from hardened high-speed steel with a titanium nitride coating for long-lasting use.  It uses a heavy-duty 3/8” shank, far superior to the 1/4” hex drive style bit found at discount tool stores and is dual-flute to provide fast, smooth cutting.  One 1699 Step Bit replaces 12 different sized standard bits. Its great for installing your favorite Jeep accessories and even works well as a deburring tool. For more info head online tp or stop by your local JKS distributor.
