Holbrook - I don\'t get it

They say they make longer leafs. If they're longer, to fit'em you relocate your main leaf mounts (those welded on the frame towards the centre of the Jeep). But if you do so, then the axle IS NOT sitting in the center of the leafs. Is that OK? You have like 2/5 of the leafs in front of the axle and 3/5 in the back (for the front, that is).
Then, they say it gives you a 3" lift with no additional problems (driveshaft, steering, etc). How? I mean, you DO lift the Jeep, leaving axles where they were (their distance from the ground), but lifting everything else. T/C, engine etc go UP while diffs stay down - angle has to change! Steering linkage - the same.
Where am I wrong here?

Re: Holbrook - I don\'t get it

The springs you refer to are very similiar to the stock Jeepster & Commando springs from '66-'73. Yes the axle can sit other than center of the spring. Usually a 3" lift doesn't come with too many of the problems you refer to, but I wouldn't take it to the bank until I heard from others that have done the same mod. These springs are made in Portland, Oregon by Benz Spring Co. for Holbrook. Benz also made my 3" lift springs for my Jeepster and I'm happy with them so far, but I do have more leaves than what Holbrook uses for a smoother ride.

Re: Holbrook - I don\'t get it

the center pin is not in the center of the spring. So one length Center pin to spring Eye is say 26", the other maybe 34". You leave your axle in the same place, but move only the spring mounting point.

did that make sence?

Re: Holbrook - I don\'t get it

Will jeepster and commando springs produce a lift?

Re: Holbrook - I don\'t get it

After 30+ years of abuse, most jeepster/Commando springs can barely hold themselves up....much less the entire vehicle [img]images/graemlins/grin.gif[/img]

On a side note, XJ rears are not *that* much shorter, have very similar offset center pins, & there are several aftermarket vendors making lift packs for them.... I'll post the similarities later (my data is in 3 places right now [img]images/graemlins/frown.gif[/img] )

Re: Holbrook - I don\'t get it

I'd be interested in seeing about the OffSet XJ lift springs, I'd assume u could fab this up pretty easily yourself.

Anyone have experience with the HoldBrook springs?
or Making the XJ springs all around? [img]images/graemlins/RockOn.gif[/img]
