Last time I checked into this- several months ago (unless Rock Krawler has revised things), these are the reasons that I decided to chose the Poly Performance tie-rod over the Rock Krawler. JMO
*Heavy to the point that it seems like overkill for the JK.
*Not a direct fit. It utilizes Chevy/ Moog 3/4 ton rod-ends, which must be purchased separately (at around $75 each).
*Need to ream out the OEM knuckle for installation.
*Must remove to make adjustments.
*No flex. With extreme abuse, any hard hits will be transferred to the rest of the axle assembly, knuckle, etc.
*Larger than stock diameter, so the OEM and other aftermarket clamps/ stabilizer mounts will not be compatible.
*Includes rod-ends that require no modification to the OEM knuckle to install.
*Fully adjustable at both ends without removing.
*Small amount of flex, which absorbs some of the hard hits.
*Compatible with OEM and other stabilizer clamps/ mounting hardware because it is the same diameter as stock.
*Zirk fittings on both ends.
***My Poly Performance components have taken some serious abuse and still have not needed any adjustment.
