15 Bolt
Rear Ends
$7,225.00
If you want the ultimate all around best of the best rear-end for demolition derby than look no further than the 15 bolt. The 15 bolt gets its name from taking a GM Corporate 10.5 14 bolt and shaving the bottom two inches from the case. With the addition of a fabricated plate to close the machined case up you are left with 15 bolts to attach the cover.
The 15 bolt features a massive 10.5” ring gear and 40 spline axles that can handle all of the horsepower and abuse that you can throw at it.
Our 15 bolt starts with a GM 14 bolt full float housing from a full-size truck. The axle tubes are replaced with new 3” OD ½” wall DOM tube. The case is then precision machined to remove the lower two inches and reconfigured. The housing is outfitted with CNC machined billet housing end/axle savers to house the massive 40 spline hobby stock axle shafts. The rear-end is assembled with a new spool, bearings and gear ratio of your choice that are also shaved to fit the newly modified case. A full truss brace, top brace, back brace are added to this housing to provide complete protection. Fabrication is rounded out with precision jigged ¾” upper trailing arm ears, Coil/Leaf lower mounts, threaded coil spring perches, pinion brake, pinion brake protector and a fabricated cover.
