Both the Gas-a-Just and the Monomax are high pressure N2 charged shocks at 280psi. I've never seen either, but would guess they're pretty tough to move by hand. I tried a set of Heckethorn 9000 shocks on a Suburban once - hated them. They were 200psi charged and it was all I could do to move them. Rode like a brick, but sure cornered great at speed. I also installed Rancho 9000s with twin compressors/gauges on the Suburban. They weren't much better and forever leaked.

Guess I'm a little different than the crowd, 'cause I like a low pressure shock with good damping, which lets the suspension work. I've used Monroe Sensatrac on the last several trucks, but I don't like them on the Raider as much on other trucks (Ramcharger, Cherokee, Suburban and Yukon). I think it's because the Raider has a narrow track and more tophamper which results in exaggerated body lean, but I haven't driven it enough to quite figure it out yet. Maybe a 10.50 tire would help.

If you haven't bent or dented your shock, it's probably ok - just stiff..... remember your 180 lbs is nothing compared to the forces generated by the truck and the road.
