Could anyone please advise if there are any upgraded aftermarket shock absorders and/or stiffer coil springs for the Freel2 TD4. I am currently at 80k miles and tow a 14ft Ifor trailer quite frequently. The suspension does not feel as tight as it should and my lr dealer says that all components are fine.

Has anyone had to change shocks due to wear and tear, if so at what mileage? 80K of hassle free motoring.....cracking little motor!
