This is our new Heavy Duty Lower Control Arm (LCA) Frame Brace Kit first featured on BigMike's 2016 Tacoma! This unique and feature filled kit is Patented #11046135 and made right here in the USA!

This is the Ultimate IFS Gusset Setup that goes far beyond the Cam Tabs!

» LCA Flange and Cam Tab Gusseting

USA-made 1/4" thick H.D. Flange & Cam Tab Uprights

— Quarter inch plates are added to the outer walls of all 8 LCA mount flanges
— Nearly quadruples the thickness of each LCA flange wall!
— Greatly resists deforming or bending of cam tabs under severe impacts or bottoming out while jumping

• Installs over the top of existing factory Cam Alignment Tab Plates

— No drilling 24 spot-welds or having to chisel factory parts off with a hammer
— Simply rest each Heavy Duty Upright against each LCA flange and weld in place
Greatly reduces install effort and time

• Completely encompasses all 16 factory cam tabs

— Outer tabs receive a 1/2" section of 1/4" material
—— TWICE the strength of 1/4" cam alignment tabs
— Inner tabs receive 2.0" X 1/4" of material
—— Inner tabs receive the most stress from objects on the trail
— We guarantee you will NEVER bend a cam tab again!

• Can be installed over aftermarket Cam Tab Gussets

— If you already have aftermarket 1/4" Gussets installed, simply grind just an 1/8" from each inner face of our H.D. Uprights and install as normal

» LCA Frame Mount Gusseting

USA-made 1/4" thick H.D. Lower Bracing

— Quarter inch plate is also added beneath each LCA mount
— Full 8-point Front & Rear LCA Frame Mount Gusseting
— Distributes forces across a wide contact area of the sub-frame assembly
— Converts each LCA flange pair into a very strong double-sheer design
— Bridges gaps between flanges to prevent catching edges on rocks
— Greatly resists deforming or bending of LCA flanges under severe impacts or bottoming out while jumping

• Angled Front Lower Brace deflects rocks and other objects

— Protects Cam Tabs and Alignment Hardware from direct impact
— Gently shifts alignment hardware safely away from objects during Rock Crawling

» Additional Features

• Can be installed without removing anything!

— Most of the kit can be installed (welded) without removing any hardware or control arms
— Eliminates the need for suspension re-alignment
— Ideally you'd want to finish inner flange welds and paint, but this isn't "required" and could be completed at a later date

• Retains all original alignment hardware

— If you choose to remove LCAs during installation, you can easily mark the position of all alignment parts and reinstall extremely close to the original alignment spec.

• Compatible with both factory and aftermarket suspension arms

— Does not interfere with or restrict the range of motion of any LCA we've seen so far
— Frame braces are clearanced for grease zerk access of aftermarket-style serviceable bushings

• Recesses and protects Alignment Hardware

— H.D. Uprights are thicker than the indexed flange of each eccentric fully protecting them from forward or rearward impact with objects passing under the truck
