Stop wasting money on premature transmission failures. Over 68% of transfer case issues trace back to inferior input shafts. That grinding noise? Worn splines chewing through your drivetrain.
Rebuilds cost $1,800 on average. Your NP231 or NP241 transfer case deserves precision-engineered solutions. Install a spline system that actually lasts.

Standard shafts bend under torque. Premium 29-spline inputs handle 25% more load. We use aerospace-grade 4340 chromoly steel. Heat-treated to 50 HRC hardness. Result? Unmatched durability.
Handles 550 lb-ft vs standard 400 lb-ft
120,000 mile warranty coverage
0.001" tolerance machining
Not all shafts match every system. Let's compare specs so you get the perfect fit:
Model | Spline Count | Length (inches) | Max Torque (lb-ft) | Price |
---|---|---|---|---|
Standard 29 Spline | 29 | 6.25 | 400 | $189 |
Our Premium 29 Spline | 29 | 6.25 | 550 | $229 |
NV149 32 Spline | 32 | 6.75 | 500 | $269 |
NP241 27 Spline | 27 | 5.75 | 350 | $169 |
NP231 27 Spline | 27 | 5.75 | 350 | $169 |
Notice the torque advantage? Our heat treatment process adds real strength without size changes.
Lifted truck? Heavy towing? Standard shafts won't cut it. We offer:

(29 spline input shaft)
A: The 29 spline input shaft connects transmissions to transfer cases in Jeep and Dodge 4WD systems. It's commonly found in NV241 transfer cases for heavy-duty torque handling. The 29-spline design offers balanced strength for moderate off-road applications.
A: Yes, NV149's 32-spline shaft handles 30-40% more torque than 29-spline versions due to thicker teeth and larger diameter. This upgrade is popular for extreme off-roading or high-power engines. Always verify transfer case compatibility before swapping.
A: No, NP241 27 spline input shafts are incompatible with 29-spline transfer cases due to size and tooth count differences. Mixing spline counts causes catastrophic gear mesh failure. Always match spline counts when replacing input shafts.
A: Most TJ Wranglers (1997-2006) utilize NP231 transfer cases with 23-spline shafts, not 27-spline. The NP231 27 spline variant typically appears in Chevy and Ford trucks. Verify spline count with VIN decoding before replacement.
A: Inspect for stripped splines near the transmission coupling or rotational play exceeding 5 degrees. Check for metal shavings in transfer case fluid indicating tooth wear. Replacement is recommended if grooving exceeds 0.5mm depth on spline surfaces.
