Introducing our Heavy Duty Lower Control Arm (LCA) Frame Brace Kit, the Ultimate Gusset Setup for all off-roaders! This unique and feature-filled kit goes far beyond cam tabs, taking IFS Type-3 gusseting to a whole new level. Beef up your 2003-2009 4Runner, 2006-2009 FJ Cruiser and 2003-2009 Lexus GX470.
The Marlin Crawler HD LCA Frame Brace Kit offers exceptional strength and protection. Crafted from USA-made 1/4″ thick flange & cam tab uprights, the outer walls of all 8 LCA mount flanges are reinforced with quarter-inch plates, quadrupling their thickness, and all 16 factory cam tabs are fully encompassed, providing unmatched strength. This combination prevents deformation and bending of cam tabs, even under severe impacts or bottoming out while jumping.
Our kit further enhances strength by adding plates beneath each LCA mount, converting each flange pair into a strong double-shear design. It also bridges gaps between flanges, protecting against damage from rocks and impacts. An angled front lower brace deflects objects, while the added material recesses and safeguards cam tabs and alignment hardware from impacts.
Stable alignment is crucial for on- & off-road driving performance, and our kit delivers. It has been tested with up to size 40″ tires on various rigs, including manuals, automatics, and Dual + Triple transfer case setups of all compatible types and models. Factory alignment hardware remains secure, ensuring precise alignment even in extreme conditions, as proven in Ultra4 & King of the Hammers (KOH) rock racing events.
To install, simply place each Heavy Duty Upright against each LCA flange and weld in place. No drilling or cutting spot-welds required. Installation may be performed without removing any hardware or control arms, eliminating the need for suspension re-alignment. If you already have aftermarket 1/4″ gussets installed, our kit can be installed over them with simple grinding adjustment as shown on the installation page. Our kit is also compatible with both factory and aftermarket suspension arms, allowing for unrestricted range of motion. Depending on application, your skid plate may or may not need to be modified for clearance. Please click here for example skid plate install pictures and more info posted to our forum.
Gear up your rig with our Heavy Duty LCA Frame Brace Kit and experience unrivaled strength, durability, protection, and peace of mind knowing your alignment is safeguarded for any terrain.
The Marlin Crawler HD LCA Frame Brace Kit is patent-protected (#11046135).

— 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

— 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!

— 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
• Stable Alignment Proven with up to size 40″ Tires
— For over years we have never had factory alignment hardware come loose or alignments go out on our own rigs running 40″ tires with manual and automatic transmissions, Dual and Triple transfer case Rock Crawler Tacomas and 4Runners. Further, we have a dozen more running 40″ tires and two V8 4Runners on 35s competing in Ultra4 & King of the Hammers (KOH) rock racing events running our HD Frame Braces who have yet to report a loss of alignment. With any mechanical device, routinely maintain proper hardware torque and Toyota’s proven design of factory eccentric hardware will never let you down!
