Is it agri or commercial axles? If they're Granning, take your bits to a local truck factors and get them to compare it ROR in their catalogue.
10 stud but I know it's not the full HGV standard drums (can't remember measurement off top of my head) it's slightly smaller. I think newer ones are called LX and the bigger brakes are HS high speed. I should have tried hunton legg they have always been good for our marstons but the genuine spring wasn't bad money and thought it be quick and easy to have it replaced!

No idea where you’re from but I’d be amazed if our local Richard Western dealer, Robert Davies, from Ford near Shrewsbury didn’t have them in stock, I know when I broke a spring on an AW trailer some years ago I took it there and he had several pallets of different sized springs.Anyone know where I can buy non genuine parts for Richard western trailers? Last time I ordered some bits they took ages. Ordered a spring 10 days ago and dealer has no idea when it will arrive. A spring for a 2012 trailer should be a stock item?
