Sport Altitude - Heavy Duty Suspension w/gas shocks


Staff member
Couldn't tell you for sure but typically, heavy duty typically means different spring rate and shock size and or valving. More times than not, the springs can carry a heavier load and shocks are designed to not fade with hard use. Of course, ride quality is 100% subjective so I couldn't tell you if the ride would be better or not for you specifically.

Thanks. I figured heavy duty was not a bad idea since I got the heavier diesel. I didn't know what was different with "heavy duty". All JL's I've checked have normal suspension except Altitude. I'll know soon. Jeep JL Sport Altitude is scheduled for delivery next week.
