Ultimate Dana 44 CV Axle Set for Jeep JK Rubicon 300M

Vendor fitment: 2007-2018 JK Wrangler. Suspension & lifts with 4 inch lift-height data from the vendor source. Confirm final options and fitment on the vendor page before purchase.

RCV Performance Ultimate CV Axles simply replace your Jeep JK's weak Dana 44 U-joint axle shafts with a high-strength constant velocity design. Tests prove Ultimate CV Axles to be twice as strong as OEM Jeep JK shafts, and they're just as tough at a straight angle as they are at extreme angles - where U-joints are weakest. Ultimate CV Axles also eliminate U-joint binding to allow smooth transfer power to the ground. Even if you have big tires and big power there are no worries. Ultimate CV Axles are low maintenance and operate with a smoothness you can feel - whether off road or on the street. And we back it all with a "No Questions Asked" limited lifetime warranty. Axle set includes right.

Question

What lift height is this for?

Suspension lift height

This is a 2.5-3 inch lift-height family. Verify the exact engine, drive side, spring-capacity variant, and loaded vehicle weight before quoting because those choices can change final stance.

Fitment and build notes

Vendor catalog record promoted for browsing. Final fitment, install dependencies, and shopper selection still require review before checkout.

For a lift, the last check is the complete Jeep setup: exact year/model/trim, doors, engine, lift variant, target tire size, wheel width and offset/backspacing, bump stops, flare/fender clearance, gearing, spare support, added bumper/cargo weight, and whether a shop is installing it.
