Denny's Driveshafts: How to Choose and Order the Right Custom Driveshaft or Driveline Part
Denny's Driveshaft and Driveline Parts is a specialist shop that has been building custom high-performance steel and aluminum driveshafts for 50 years, and it also sells the individual driveline components to build or repair a shaft yourself. It's the right fit if you need a high-speed, high-RPM balanced driveshaft for a street rod, race car, 4x4, truck, van, or kit car, or if you already know the specific yokes, U-joints, bearings, gears, or seals you need. It's not the place to start if you haven't identified your vehicle's make, series, and measurements — those determine everything downstream.
What Denny's actually sells
The catalog splits into two broad halves, and knowing which half you need is the first decision.
Custom driveshafts, organized by application and material:
- Nitrous Ready 1350 Series Driveshafts
- Street Rod Driveshafts and Street Rod HD Driveshafts
- Aluminum Driveshafts
- Cobra Kit Car Driveshafts
- 4x4 Driveshafts
- 2WD Driveshafts
Driveline parts, for building, repairing, or upgrading a shaft or rearend:
- Yokes: end yokes, flange yokes, pinion yokes (front and rear), slip yokes, weld yokes and tube yokes in steel and aluminum, transmission and transfer case bolt-on yokes
- Universal joints and CV parts, including double cardan and all-CV components
- Tubing in aluminum and steel
- Bearings, differential bearing kits, bushings, seals, slip yoke dust caps and rubber boots
- Gears (ring and pinion), ring gear bolts, differential parts, shims, baffles, slingers, thrust washers
- Axles and front/rear diff parts, 4x4 axles and rear diff parts
- Ball joints and king pin parts, spindles and spindle nuts/washers/studs
- Center support bearings, companion flanges, crush sleeves, hardware, grease and lubricant
- Positraction carriers and parts, PTO and agricultural parts and shafts
Brands carried include Dana Spicer (Denny's is an authorized warehouse distributor), AAM (American Axle Manufacturing), NEAPCO, Spicer Select, Yukon Gear and Axle, and DT Components bearing kits. Several part lines can be looked up by part number.
How to match a driveshaft or part to your vehicle
The site provides a Shop By Vehicle tool plus make-specific listings for Buick, Chevrolet, Chrysler, Dodge, Ford, Jeep, Lincoln, Mercury, Mopar cars and trucks, Oldsmobile, Plymouth, and Pontiac. Use it as the starting filter, then narrow by the factors below.
Selection factors that decide the part
| Factor | Why it matters |
|---|---|
| Series (e.g., 1350) | Determines U-joint and yoke compatibility and torque capacity |
| Material (steel vs. aluminum) | Affects weight, critical speed, and intended use |
| Length | Must match your measured center-to-center distance |
| Balance / RPM rating | Denny's shafts are balanced and tested for high-speed, high-RPM use |
| Application (2WD, 4x4, street rod, race, kit car) | Sets the mounting and length conventions |
| Yoke and U-joint type | Must match transmission/transfer case output and pinion input |
If you're assembling rather than buying a complete shaft, the Build It Yourself – Parts Lists and the site's Diagrams section are the intended path: pick the parts list that matches your configuration, then order each component (tubing, weld yokes, U-joints, slip yoke, etc.) individually.
Ordering details and what to expect
- Free shipping on parts orders over $99.00, per the site.
- Contact options listed on the site: 716-875-6640 and 800-955-1872.
- Denny's positions itself as a 50-year specialist in high-speed, high-RPM balanced steel and aluminum driveshafts, and as a Dana Spicer authorized warehouse distributor with a large in-stock inventory.
- The site does not publish prices in the material reviewed here, so confirm current pricing and availability by phone or through the catalog when you order.
Common fitment problems to check before you buy
Most ordering mistakes trace back to a measurement or a mismatch, not the shaft itself. Before purchasing:
- Confirm your series and U-joint size. A 1350-series shaft won't bolt to yokes sized for a different series. Check both ends.
- Measure length the way the application requires. A 2WD shaft, a 4x4 shaft, and a kit car shaft are measured differently — use the diagrams rather than assuming.
- Verify yoke spline count and style. Transmission/transfer case bolt-on yokes and pinion yokes must match the spline and bolt pattern on your vehicle.
- Check the rearend side too. If you're also changing gears, bearings, or a positraction carrier, confirm those parts match your axle before ordering them alongside the shaft.
- Match material to use. Aluminum reduces weight but has different critical-speed behavior than steel; pick based on your RPM range and application, not just weight.
If you're unsure which parts list or series applies, calling with your vehicle details and measurements is faster than guessing from the catalog.
