Long Arm Upgrade Kit | 4-6 Inch Lift | Jeep Wrangler Tj 4wd (1997-2006)

Built for Jeep Wrangler TJ owners who demand maximum articulation and ground clearance on brutal terrain, this Long Arm Upgrade Kit transforms your existing 4- or 6-inch lift into a genuine rock-crawling suspension. By replacing your factory control arms with extreme-travel long arms, you'll maintain optimal alignment while gaining up to 35 degrees of pivot articulation at the lower joints — perfect for clearing obstacles and tackling the toughest trails. Supports tire sizes up to 37 inches.

Installed and serviced at Road Runner Wheels & Tires. Most suspension upgrades go in the same day. Call (678) 400-6467 to schedule.

What's included

• Upper Adjustable Control Arms (Front) — High-pivot design allows up to 20 degrees of movement for maximum suspension travel and improved ride compliance.
• Lower Adjustable Control Arms (Front) — High-clearance geometry protects vital components while enabling extreme articulation over uneven terrain.
• Upper Adjustable Control Arms (Rear) — Matched to the front for balanced suspension geometry and consistent performance across all four corners.
• Lower Adjustable Control Arms (Rear) — Wide-pivot design delivers up to 35 degrees of pivot for exceptional wheel articulation on rocks and rough ground.
• Control Arm Mounting Brackets — Reinforce frame mounting points for secure attachment of the new long-arm geometry.
• Track Bar Drop Bracket (Rear) — Corrects suspension geometry after the lift to maintain proper driveline angles and suspension function.
• Rubicon Compressor Bracket (Front) — Repositions factory compressor bracket to clear the new control arm routing on Rubicon models.
• X-Flex Control Arm Assemblies — Fully greasable with premium Clevite OEM-style rubber bushings; massive 2.5-inch diameter flex joints with 1.25-inch threads deliver unmatched strength and reliability.
• Hardware — All fasteners, bolts, and Grade-8 hardware needed for complete installation.

Important notes

• Does NOT fit Unlimited models — confirm your TJ model year before ordering.
• A Slip Yoke Eliminator with CV Driveshaft is recommended to avoid driveline vibration and ensure smooth operation under load.
• Rubicon models do NOT require a SYE kit or transfer-case drop, but a CV driveshaft is still recommended for optimal driveline angles.
• Exhaust will need to be cut and rerouted to ensure clearance from moving suspension components.
