That’s why we include Whiteline KTA301 UCAs in our premium suspension kits.Here’s why these control arms are a game-changer for your Frontier build—and why we trust them enough to include them in our suspension kits for the D40 and D41.<hr /><h2></h2><h2>What Are They?</h2>The Whiteline KTA301 Upper Control Arms are high-performance UCAs designed for lifted D40 and D41 Nissan Frontiers. They correct suspension geometry, increase coil clearance, and include proprietary GIIro technology bushings for maximum articulation and longevity.<hr /><h2>Why They Matter in a Lifted Setup</h2>The moment you lift your Frontier—especially anything over 1.5 inches—you introduce angles and travel ranges the stock UCAs weren’t designed for. This can result in&#58;<ul><li>Coil bucket contact (CBC)</li><li>Ball joint bind under compression</li><li>Reduced alignment range</li><li>Poor ride quality and component wear</li></ul>Whiteline’s KTA301 control arms are built to eliminate these issues—permanently.<hr /><h2>Key Features of the Whiteline KTA301 UCAs</h2>✅ High Clearance Design 
The KTA301’s unique profile increases space between the UCA and coil bucket—eliminating CBC and allowing full suspension articulation under load.✅ Corrected Geometry 
With a lifted setup, maintaining correct caster and camber is essential. These arms restore proper geometry, improving steering feel, tire wear, and overall handling.✅ Whiteline &quot;GIIro&quot; Bushings 
The star of the show—Whiteline's GIIro bushings—are a hybrid elastomer bushing design that acts like a flex joint without the noise or service requirements of uniballs.<ul><li>Allow free articulation of the control arm during suspension travel</li><li>Reduce binding and resistance common with stock bushings</li><li>Improve longevity and reduce NVH (noise, vibration, harshness)</li><li>Perfectly suited for off-road and overland use where durability matters</li></ul>GIIro bushings strike a balance between comfort and flexibility, giving you a smooth ride without sacrificing articulation.✅ Bolt-On Install 
No modifications or welding needed—these arms bolt directly into place using your existing hardware.<hr /><h2>Why We Include Them in Our Kits</h2>We’ve tested nearly every UCA on the market for the D40 and D41, and Whiteline consistently delivers the best combination of&#58;<ul><li>Performance</li><li>Fitment</li><li>Durability</li><li>Noise-free articulation</li></ul>By including them in our kits, we ensure you're not only getting a lift—but a suspension system that works as intended, free from issues like coil bucket contact and poor alignment.<hr /><h2>Compatibility</h2><ul><li>D40 Nissan Frontier (2005–2021)</li><li>D41 Nissan Frontier (2022+)</li><li>Also compatible with Suzuki Equator and select Navara chassis variants</li></ul><h2> </h2>Lifting your Frontier is about more than just ride height—it’s about improving capability, comfort, and confidence.
