Fabtech Coilovers FTS2300/FTS2100 Question

What is the difference between the Fabtech FTS2300 and the Fabtech FTS2100 Coilovers?

 

I called fabtech and they answered my question, the 2300 is a basic coilover while the 2100 is a race style Co that can handle more and better for off-roading. Both of these will fit 1995.5-2004 Toyota Tacoma's.

 

When is the best time to adjust these CO's? on truck or off? Thanks

 

You can do it on or off the truck. You can bolt them in and then make sure the suspension is not preloaded, so put the front end on jacks in the air and adjust them. Or Off the truck try to put the lower mount in a vise and adjust them.

 

I have the FTS2100's not the 2300's but i cannot find the instructions for the 2100 only the 2300's. Its talking about removing the stock isolator mount from the stock coilovers then discarding the stock co's, does this have to be done on the 2100 pair? My shocks have the spacer on top with the 3 threaded holes to mount it to the frame mount with a black coil spring booster between the spacer and the coil spring. Im wanting to know if i have to compress the soil spring at all to mount these coilovers on my truck. Help is greatly appreciated.
