Review on LIFT 57105 LoadLifter Air Spring by Robert Pierce

I recently bought a 1977 Motorhome. It still had the factory leaf springs and rode very hard. Just before my first trip from San Diego to Vegas, I installed Ne Monroe gas shock absorbers. Let's say I was pretty disappointed. Didn't really notice a difference. UNTIL I GET THESE BABIES! The Air Lift 5000 kit raised the rear by about 3 inches and now rides like it's only 5-10 years old. HUGE DIFFERENCE! The only reason I'm giving them 4 stars instead of 5 is because the front and back took about 5 or 6 HOURS to install. They say a few hours behind. IS NOT IT! I asked my mechanic buddy to bring my air tools etc. Let me tell you it was worth it! GO BUY THESE. Damn if they can make my 33 year old RV almost NEW. What can they do for you?
