I have run Monroe Max on many cars and trucks. I pump mine up to 30 PSI and it raises the rear 1 inch.
On my 84 Rampage I have them and have pumped them up to 135 PSI and they stayed pumped for over 5 years now.
I had them on my 1981 Honda Goldwing Interstate. Never pumped them up past 20 PSI.
My compressor is a 26 gallon Porter Cable. I tweeked the pressure regulator and get 150 PSI at the tank. But I have replaced the chucks with better 'High Flow' 1/2" ones and use 3/4 inch copper piping. Using a 1/2 inch self winding reel I get 140 PSI at the tire chuck but I think my 10 PSI loss is in the 'Air Dryer'.
1965 Barracuda with a F body 8 1/4 rear, 15x7 real Cop car Ralleys hanging 275/60 15. I have stock 65 A body springs but added 1 extra short on the left forward and added 1 cut down D150 spring under the first long sprin. Rancho 9000 shocks. So 6 total leafs on both sides. Never rub unless I have 3 riders in the back seat.
