The OEM shocks are Gabriel old school dual tube oil filled shocks, made in India for Mahindra. They work like they are designed to do, that is simply dampen the spring motion. However, if you are used to modern gas filled shocks, which react quickly, you will be disappointed in the 1940s style OEM shock. If you choose to upgrade, the easiest thing to do is just order some single tube Bilsteins from Diesel Freak. Wade has them kitted out with what you need depending on whether you are running stock, OEM lift, several other lifts etc. If you are not sure which kit to order, just call Wade and tell him exactly what you have and he will hook you up with what you need. You will not be disappointed in the Bilsteins regardless of how you drive.
