sorry I'm new but what does all that mean. the higher the number the stronger the axle is? or is it the higher the number the higher the ground clearance? please help.

thanks much

Dana 30's are jeep front axles. 44's can be front and rear along w/ 60's. The larger the number, in this case relates to greater strength. However it does not mean greater ground clearence. Anything else you were wondering?

Yeah what's a 35-spline dana 60? What does that mean?  

ARB? Is that the name of the company that makes the axle? So the ARB AIR LOCKER is used to engaged the differential from open to lock to get more traction?  

35 spline means there are 35 splines on the axle shaft (its stronger than a 30 spline) and dana 60 means its a good axle lol  

Lol, 35 spline axles are structually stronger than any lesser #.  ARB is company which makes lockers along with other things including bumpers and snorkles. The ARB Air Locker is a carrier in your axle which uses air from an air line to go from a open differential to a fully locked one. This means that when locker, both tires will recieve equal amounts of power at all times.

Welcome! Not a bad question either, Dana axles are very popular and can be found under a variety of vehicles throughout the years not just Jeeps. Generally, the larger the ring gear and axleshafts, the stronger the axle is, the more splines an axleshaft has makes it stronger since the torque is distributed over more splines.  Of course the big daddy is the Chevy 10.5" full floating 14 bolt. You might also hear about Chevy 10 or  12 bolt, Ford 8.8" and 9" axles.

There are many articles on axle identification, try a search on the 4WOR website for old articles.
