Ultimate Flexibility and On-Road Comfort
Elevate your Jeep Wrangler TJ/LJ (1997-2006) with the Crawl Series Front Control Arms Set. Engineered to deliver unmatched off-road performance and superior on-road comfort, this set includes a pair of Front Upper Control Arms and Front Lower Control Arms. Designed for enthusiasts who demand precision, flexibility, and durability, these control arms offer a significant performance upgrade over factory and competitor components.
Key Features and Benefits
- Unparalleled Flexibility – Featuring Johnny Joints at all connection points, these control arms allow for maximum articulation, ensuring smooth suspension travel and exceptional off-road performance.
- Precision Adjustability – Designed to accommodate lifts from 0 to 6 inches, these control arms enable precise alignment correction, axle re-centering, and optimized pinion and caster angles.
- Enhanced Durability – Constructed from heavy-duty DOM tubing—1.75" OD for the lowers and 1.5" OD for the uppers—each control arm is built to withstand extreme off-road conditions while maintaining reliability and strength.
- Complete Suspension Solution – Pair these control arms with our Crawl Series Front Track Bar for a fully dialed-in front suspension system that ensures optimal alignment and stability.
Engineered for Precision and Strength
The lower control arms are constructed from 1.75” OD DOM Tubing with a robust 5/16” wall thickness, while the upper control arms utilize 1.5” OD DOM Tubing with the same impressive wall thickness. These materials far exceed industry standards for durability and performance. The Johnny Joints at both ends provide unmatched articulation and longevity, ensuring your suspension can handle the toughest trails while maintaining a smooth ride on the highway.
Two-Stage Powder Coating for Maximum Protection
Our control arms undergo a rigorous two-stage powder coating process to ensure superior corrosion resistance and durability. A zinc primer base coat protects against rust, while a top coat, available in 10 vibrant colors, adds a personalized touch and further safeguards your investment.
