Kartek Off-Road 29-1/2" Total Length 300M 33 Spline Porsche 934 Racing Solid Axles

Our American made 300M IRS axles are specially designed for the needs of today's off-road racers. The axles are machined from 300M steel alloy. The axles can be ordered as either solid or gun-drilled, and in virtually any length.

All of our axles are REM "polished". The REM ® procedure is not a polishing process but rather a finishing process. REM Surface Engineering’s Isotropic Super Finishing or ISF ® gives our axles a near mirror like finish. This translates to a perfectly smooth plunge of your axle through your CV joint.

Measuring axle length for VW Stub axle, Micro Stub Axle, or Mid-Board Micro Stub Axle

• Check your toe in/out wheel alignment.
• Lift the hub up, so that if it did have an axle, the axle would be at zero degrees, parallel to the ground.
• Measure from the BOTTOM of the drive flange cup on the transmission to the BOTTOM of the stub axle cup on the brakes. Reference Figure A
• Subtract 1/4" to 3/8". That is your TOTAL axle length.
• Check both sides of the vehicle. It is very common to have two different length axles.
• Now use a PVC pipe as a mock-up axle. Cut grooves 1/4" down on either end into each end of the PVC for your clips. Install your CV joints and mock-up axle.
• Lift the vehicle so the tires drop down to full droop.
• Grab your mock-up axle and make sure that you have 1/4" to 3/8" free play. Reference Figure B
• If you have 1/4" to 3/8" free play at zero degrees and at full droop then you're perfect.

Measuring axle length for Mid-Board Foater Hub or Out-Board Floater Hub

• Check your toe in/out wheel alignment.
• Install CVs on the transmission and on the hub side.
• Lift the vehicle so the tires drop down to full droop. Reference Figure D
• Measure from OUTSIDE edge of star to OUTSIDE edge of star. This is your clip to clip dimension. Add 1/2" and that is your TOTAL axle length dimension.
• Check both sides of the vehicle. It is very common to have two different length axles.
• Now use a PVC pipe as a mock-up axle. Cut grooves 1/4" down on either end into each end of the PVC for your clips. Install your CV joints and mock-up axle.
• Grab your mock-up axle and make sure that you have 1/4" to 3/8" free play at full droop and at zero degrees. Reference Figure C and Figure D
• If you have 1/4" to 3/8" free play at zero degrees and at full droop then you're perfect.
