I’ve been running OME suspensions for a very long time. 2850 J springs with 60070L shocks in my front and 2864 springs with 60071 shocks in the rear. My cruzer scales out at 7,000 lb loaded and our trailer weighs 1,000 lbs. loaded. Are the shocks a bit tight? Heck ya, and you’ll really appreciate that when you’re cruising along at 70 mph with side winds of 30 mph plus. Or trucking down a narrow crooked mountain pass. Or if you need to make a quick emergency maneuver. My cruzer hugs the corners and stays nice and tight in heavy winds.. My first set of shocks lasted well over 100,000 miles. I say that cause I swapped em out at 80,000 miles and they were still in perfect functional condition, I just figured it to be a PM before our 10,000 mile trip last fall. OME and Toyota is a perfect fit every time. Case closed. Oh BTW, those BP51 are a dream, that’s about it. Unless you have tons of expendable income, or if you are planning on shipping your rig to Africa or Australia and partaking in some very long range off pavement driving, then those bp51 shocks are overkill here in the states. Good luck with your decision.
