Replacing Rear Lever Shocks with Tube Shocks

Share this page

KVH, sure that is probably the easieast fix. I went with the bolt to the shock mount tube shock conversion on my TR250, if I had read more like this I might not have done it, but at this point not going to go back, will see what happens, haven't driven with too much verve yet, still breaking it in.
 
From what I remember. tube shock conversions were a cheap alternative to replacing lever shocks on the straight axle sportscars.
Seems like if there was money to be made by coming up with a rig to keep the sales going for IRS cars, that's what happened, regardless of the consequences.
It's just a rig, defying the geometry of the suspension...IMO, of course.
 
Replacing Rear Lever Shocks /Tube Shocks/Follow Up

Reading all the material here, I'll try keeping my lever shocks and I'll fasten them to the rear differential bridge with a bolt that goes all the way through.

I'll use either a nyloc locknut or a good lockwasher and nut. Hopefully, there won't be play that will cause the bolt holes to wear, oblong or otherwise. I actually have a good shank bolt that seems a fairly good fit.

I thought of drilling out the stripped threads for a bigger size, but I'm not sure that would be a superior fix, and it doesn't appear I'd have room for the drill (or a steady enough hand to assure and good bore).

Unless anyone has a stern warning, that's my plan.

BTW, can anyone tell me what oil weight is used inside the lever shock?
 
Re: Replacing Rear Lever Shocks /Tube Shocks/Follow Up

You might consider an all-metal lock nut rather than nylocs... others may also have opinions on this. Some blue thread-locker might also be a good idea, this is a location that can take a beating on our 'fine' roads.

I'm using motorcycle fork oil in my levers -- I'm thinking 20 weight is what I got.

I used some bolts with allen-heads for the shocks as those were way easier to hold and tighten compared with the usual hex-head bolt that required a screwdriver jammed in place to hold the head -- but that was on a non-IRS car so maybe the IRS shock doesn't have that clearance issue.
