14 Bolt Straight Axle Assembly with unit bearing cups (accepts up to 47 spline shafts)

Are you wanting a BAD TO THE BONE axle that wont break the bank?  The GM 14 bolt is the way to go.  

We have been around the block and seen the evolution of axles.  The 14 bolt axle is hands down the strongest "for the money" axle in the 1 ton arena.  Its relatively light weight and super strong for its size. 

This axle trumps the Dana 60 in strength due to its larger ring and pinion gear and a 3rd bearing on the snout of the pinion that keeps gear deflection down. 

Some of the biggest players in the offroad game have chosen the 14 bolt for its simplicity in gear set-up and brute strength.  Racers and trail riders know the 14 bolt will take a straight beat down and keep going.  This axle is what we recommend for guys running up to 800hp. 

*LABOR: IF YOU WOULD LIKE A PART, BUT DO NOT WISH TO HAVE BUSTED KNUCKLE OFFROAD INSTALL IT, SIMPLY DO NOT CHECK THE INSTALL CHECK BOXES.

*BASE PRICE IS FOR A RE-TUBED AXLE HOUSING WITH OUTER CS INSTALLED.

OFFESTS: We re-tube the axle with 3.5" x .500" wall D.O.M. tubing.  The centered offset will work in most buggies but if you need a specific offset for your axle we can build it to your specifications. There are tons of options on how we can build your axle.  If you do not see your configuration please give us a call and we can custom build whatever you desire. 

SPOOLS/LOCKERS:  We offer 30 spline, 35 spline, and 40 spline spools and lockers for 14 bolt axles.  Spools are the strongest option.  Lockers will allow the vehicle to turn better when not on the throttle but are not as strong and are more aggressive on axle shafts. 

RING AND PINION GEARS: Yukon ring and pinion gears are used standard in our axle assembly.  We also have USA gear, Motive gear, Nitro gear, and Factory GM pull-out gears. Newer style ribbed housings have install kits that are slightly more expensive. 

YOKES: We only offer forged u-bolt style yokes for 14 bolt axles. They are available in 1350, 1410, 1480, and Rockwell pattern flange yoke styles.

CUPS AND UNIT BEARINGS:  Because of its incredible strength and lost cost, we use Mark Williams unit bearing cups on these axles. The cups are welded to the axle housing and allow to run tried and true unit bearings. They have many advantages over the classic spindle / hubs, they are cheaper, stronger, will accept any size axleshaft up to a 2" 47 spline, are easier to work on and have built in wiper seals to keep dirt and contaminates out of your axle tubes (inner axle seals are still required). We use tried and true unit bearings that have been tested through YEARS of 1000+ horsepower beat downs.  They come drilled with 8 on 170mm and 8 on 6.5" bolt patterns. 

DRIVE FLANGES: Drive flanges are offered from various manufacturers. If you are using 30 or 35 spline axles the drive flange will utilize a 35 spline drive flange.  If you are running 40 spline axles the drive flange will be 40 spline.

INNER SEALS: 14 bolt axles never had seals at the differential.  When building a straight axle like this one, we use a seal housing that has multiple dual-lip seals inline to keep oil in the differential.  

DIFF COVERS: 14 bolts have a big lip on them that KILL ground clearance.  Choose one of our lifetime replacement 3/8 plate diff covers that allow 1-3/8" additional ground clearance.  We can cut the lip off the differential for you or you can do it yourself

BRAKES: We have our lightweight brake kit that utilizes a light weight factory rotor and a Willwood calipers as the standard brake option.  We also have a super light weight brake kit that utilizes Branik brake rotors and hats with Willwood calipers as an upgrade.
