I Had Air Shocks Installed In My 86 Cherokee After The Leafsprings Started To Sag. I Don't Remember Off Hand Which Brand I Had Installed, But It Was Around $500, They Placed The Inflation Nipple In The Rear Bumper. It Was Pretty Cool To Inflate It And Watch The Whole Back Of The Jeep Rise Up. If I Dig Through Some Of My Old Reciepts I Could Get All The Specs For You. If Inflated All The Way It Was Probally Like 2.5 Inches, But They Told Me Not To Inflate To Much Over 75lbs, So The Shocks Didn't Blow Out. The Ride Was A Little Stiffer But Not Too Bad.
