I'm not sure I noticed a massive difference when I took the 69 4/4 with lever arms off the road and started driving the 2006 4/4 with telescopics. However after saying that I'll be putting telescopics on the 69 4/4 during the re-build if for no other reason that the damper frame provides a bit more cross braceing to the chassis similar to the under scuttle brace tube which will also be fitted as part of the upgrade.
