Ashcroft Rear Heavy Duty Halfshaft Set
For D2 new generation of Heavy Duty halfshafts are made from "4340" Alloy Steel and are supplied with a FIVE YEAR replacement warranty against breakage.
In addition to our normal HD D2 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 £ 500/pair and are aimed at the Rally Raid customers that cant afford a shaft failure mid race.
