There are two major benefits to this spool, the first is a superior axle to spool spline interface compared to an aluminum spool, the second, we are able to lose 4.5” of axle in the middle of the spool, 4.5” of nothing but air, another pound less even with our Ultra Lite axles. If you were wondering about the spiro-lox on the drive plate end of the axles in the previous picture, now you know.

GearWorks axles are in a league of their own. At only 0.54 pounds per inch they are by far the lightest reliable Trophy Truck axle available. How do we pull that off? We start with a solid round of US made 300M 3” bar, gun drill it big and run the O.D. down just right, heat treat them and then shot peen them inside and out. There is even a threaded press in aluminum plug to aid in removal of the shaft, we were truck prep guys too you know!

GearWorks keeps in stock 36 spline drive plates for most common hubs (SPD, ID Designs, Geiser, Jimco Porter) etc, with wheel stud patterns 6X6.5”, 5X5.5 and 10X5.5”

The GearWorks 36 spline spool was designed to address several problems encountered with other manufacture’s spools. First and foremost was the issue of breakage of the bearing journals due inadequate material thickness on other 4 inch bearing type spools. Years of practical experience told us that the 2.562” 40 spline axles were more than strong enough; we decided to size it down four splines to 2.375” 36 spline. Second was the required modification of an already very expensive carrier bearing, our 36 spline spool uses the Timken L713049 just as it comes out of the box. Third, some spools center the axle in the center of the spool, this is usually the thinnest section in a spool and most prone to failure, in our spools the axles are centered at the ring gear mounting plane, the strongest part of the spool.

The Strange Engineering pinion yoke is forged from chromoly. Shown is with a pinion seal lip protector welded in place by us for off road use.

The ProLite 1¾” 40 spline final drive system was designed specifically for the ProLite 4cylinder class. Taking the Pro 24 axle family design a step further, the axle weight comes down to only .23 lb per inch! That’ right, a 28 inch axle that weighs in at only 6.4 pounds. These have been in use in several of the fastest ProLite trucks on the circuit since 2008 with an average service life of more than one full season on a set without failure. Combined with a drive plate and cap assembly at only 3 pounds each, a hollow steel spool, and an investment cast steel case assembly, you will gain reliability with nothing to lose but the weight!
