I got a free set of Trailmaster AAL's. they are part# 1536. On the Trailmaster site the XJ calls for part# 1538.

The 1536 fits many Toyota, Mitsubishi, Isuzu and Datsun trucks.

Looking at the spring specs the free arch, length and width are identical between these 2 part numbers.

Would it be OK to put these in the XJ? I'm assuming the only difference would be spring rate but don't want to end up breaking anything.

 

Oh well....Guess I'll just have to put them in and see what happens.

 

I would say you should be fine- many people (myself included) experiment with different bastard packs which are basically a junkyard AAL. As long as it is a 2.5" wide spring it will fit, the lift you get may be more or less than the "advertised" amount.

I say go for it!
