Northeast Mod Snub Nose Quick Change
As engine setback in Northeast Modifieds has increased, driveshafts had to be shortened and installed at a more severe angle to connect the transmission with the rear. Recognizing that this geometry created excessive stress and premature failure in U-joints, we developed the Northeast Mod Snub Nose quick change—a full-size rear that's 3" shorter than a standard quick change. Since their introduction in 2025, dozens of NE Mod teams have made the switch and are finding themselves in victory lane weekend after weekend. Here are some of the features of the Snub Nose Quick Change:
• Shorter center section to allow for a longer driveshaft installed at the proper angle.
• Billet steel yoke supported by its own bearing, which is designed to absorb the stress put on the rear when the car is in posture.
• Lower change gear interposed between two directly adjacent bearings supporting the lower shaft, creating a floating lower shaft with four bearings.
• Permanent Mold A356-T6 center section and side bell castings—the strongest production quick change castings available.

Northeast Mod Two-Piece Driveshaft
Our Northeast Mod Snub Nose Quick Change improves Modified driveline geometry by allowing more space for a longer driveshaft between the transmission and the rear end. Now our Two-Piece Driveshaft takes those improvements even further.
• Allows 2 full inches of travel—a half-inch more than standard three-piece shafts.
• Maintains 2-3/4" engagement at static.
• Two-piece construction eliminates chatter on deceleration, and integrated vents provide unrestricted compression and extension.
• Integral grease fittings for easy lubrication while driveshaft is in the car.
• Bolt-on trunnion caps ease removal and installation
All Northeast Mod Two-Piece Driveshafts come with a Cerakote finish to prevent rust and decrease friction, and they're available in 1310 (P/N 13482) and 1350-series (P/N 13483).
New Sprint Quick Change Features
The latest evolution in our full-size Sprint car quick changes has been driven by observations made in the pits and feedback from racers, crew members, builders and owners about how we can make their job easier and help get them around the racetrack quicker—and get them home safely at the end of the night. All of these upgrades are now standard on all full-size Sprint rears.
• Spoiler Gear Cover (P/N 13405) shrouds the top high nuts to minimize the risk of their edges puncturing the fuel cell in the event of a crash. The gear cover also features an updated O-ring groove that keeps the O-ring in place during gear changes.
• Center section incorporates an internal passage connecting the main cavity with the change gear cavity, improving ventilation, reducing pressure and keeping the rear cooler.
• Redesigned shifter (P/N 3000-2) has a splined shaft so the shift arm can be easily clocked to the exact position needed for your car, as well as extra O-rings for improved sealing and a locking jet nut to replace the old-style retaining ring.
• Banzai Bolts and Nuts are drilled and grooved for safety wire to ease wiring the bell to the center. Available in steel (nuts P/N 13260 and bolts P/N 13200) and titanium (nuts P/N 13260T and bolts P/N 13200T).
• Viton/Teflon axle and swivel ball coupler seals reduce friction (and grooves) and withstand higher temperatures (axle seal P/N 7224VT and coupler seal P/N 7280VT).
• Shorter, flanged high nuts (P/N 13283) and shouldered studs to spread the load during installation. Studs available in steel (P/N 13201) and titanium (P/N 13201T).
• Larger breather tube with integral clip improves ventilation and keeps breather tube in place (P/N 13456).

Permanent Mold 10-inch Rears
Racers are achieving unheard of levels of mechanical grip and stressing driveline components more than ever. To ensure our rears continue landing in victory lane, we're introducing a structurally reinforced center section and have invested in permanent mold tooling capable of producing castings far superior to the sand cast components currently on the market.
The design improvements include:
• Thicker and longer internal ribs extending into the front snout and rear gear cavity
• Larger fillets (i.e. thicker metal) at bell mounting flanges for added torsional strength
• Dual support ribs between the change gear cavity and the ring gear cavity
• New center weighs the same as the previous iteration of our race-winning rears
But the most significant improvement is in the Permanent Mold casting process, which produces castings that are stronger, denser and more consistent than the sand cast quick changes on the market.

Remote Breather & Oil Fill Tanks
Venting your quick change rear in your hot rod, Pro-Touring car or truck or Drift racer can be accomplished with a simple fitting installed in the rear end housing. But these new Remote Breather & Oil Fill Tanks are a much cooler looking way to get the job done. Simply mount the tank in your trunk or truck bed and connect it to the quick change through the floor using whatever 6AN fittings and 3/8-inch line fit your style. The knurl-grip vented cap provides proper venting, and the tank also acts as a funnel for quickly refilling oil after gear changes. We collaborated with Mooneyes to develop a spun aluminum tank and cast bracket reminiscent of the vintage Moon fuel tanks found on hot rods, circle track racers, and drag cars going back to the ’50s.
The tanks are available in two sizes—4" and 2-1/4" diameter—and come with cast aluminum brackets with rubber grommets, and mounting instructions and a pattern for easy installation (hardware, fittings and hose not included).
