Model:  ASHNSR


Our new generation of Heavy Duty halfshafts are made from "4340" Alloy Steel and are now supplied with a FIVE YEAR replacement warranty against breakage
These shafts are made to fit the later "slim" hub driver (15mm) as fitted to the 300 TDI vehicles.
Our rear shafts will need a pair of separate outer drive flanges if you don't already have them. Halfshafts for the 90 rear up to Vin No LA930456 have seperate flanges so it will not be necessary to replace your existing flanges unless you wish to upgrade to our heavy duty flanges. Halfshafts after this Vin number have integral flanges so it will be necessary to purchase both the halfshafts and the 859 drive flanges.
The halfshafts and drive members we provide are warranted against BREAKAGE, not against wear caused by 'fretting corrosion' of the spline/drive member interface. This 'fretting corrosion' is a direct result of lack of lubrication, a design fault, and is common on grease filled hubs. We therefore recommend removing the half shaft seal to allow oil to migrate along the half shaft to keep the spline lubricated.
In addition to our normal rear shafts which are made of the 4340 material we have made a limited quantity of these shafts in 300M material. This 300M is in theory only about 20% stronger but is much more elastic, we have also reduced the main shank diameter down by 2mm to ensure the whole shaft can flex and we have no stress concentrations at the spline ends. These are more expensive at £ 450/pair and are aimed at competition users that cant afford a shaft failure mid race.
