Description
⚡ Usually ships next business day. During high demand periods, allow 2–4 weeks for production.
The Wicked Wrench Motorsports 8L90 / 10L90 to Jeep 241J Adapter, Spacer & Clocking Ring Kit seamlessly bridges your modern GM drivetrain to a Jeep JK, TJ, or LJ 241J transfer case. Specifically engineered for Gen V LT engine swap applications, this adapter connects a 4x4 automatic GM transmission (8L90, 8L90E, 10L80, or 10L90) to the Jeep Wrangler 241J transfer case at an ultra-slim 3/4-inch overall thickness — preventing excessive rearward drivetrain stretch in tight Jeep engine bays.
The multi-position clocking ring allows you to index your 241J transfer case in 3 distinct locations, letting you optimize front driveshaft angles and customize underbody ground clearance for your specific build.

⚠️ Important: A 32-spline input shaft upgrade is required. Factory Jeep 241J transfer cases use a 21 or 23-spline shaft which will not match GM transmission output. We carry the exact Wicked Wrench Motorsports Machined 32-Spline Input Shaft — add it to your order for a seamless build.
Also recommended: Jeep JK 241J T-Case Beef-Up Bracket for a bulletproof 4WD shift setup.
