These shocks were built in 2013 ?In that case I'll post my experience with Elka. Bought all four shocks for my 2013 Renegade X. Took 6 weeks to get the shocks that were directly ordered from Elka. Sales rep was less than helpful. Seals blew in less than 300KM. Ride was not noticeably better. Will never purchase another Elka product.
