Im going to be installing the Hal Qa1 shocks soon and had a couple questions. I read Fred's guide so I have a pretty good idea on to do most of the work.

1. Do I need to modify the spring seat if Im using both the Hal shocks and springs?
2. Are there any tips and tricks you guys have discovered before I set out to do this?

 

1. Hal springs are smaller in diameter and don't need the stock spring seats-so no modifying necessary.

2. I think Fred covers most everything in his write-up.

 

The ride height adjustment is really hard to do (tight - binding) unless you either put antisieze grease between the washer and the adjustment ring or place a bearing above the adjustment ring.

 

No modification required, the HAL springs fit perfectly on the HAL shock retainers. I was just using grease on the threads and ring, took the spanner wrench and gradually compressed the spring.
Some notes to Freds write-up:
Forget the lower balljoint, just separate the upper joint, it's much easier. Unbolt the nut, and tap it with a hammer. Be ready to catch the spindle if you have not removed the caliper...
It's a pretty straightforward project IMHO.

 

I found that greasing the threads didn't help, the thin washer that sits on top of the adjustment ring binds against the adjustment ring; grease this interface and adjustment is now easy.

 

QA1 has a roller thrust bearing that can replace the thin washer. It should make adjustments a lot easier.

 

I'd make sure to use the thin roller bearings. This will make it easier to turn.

 

Thanks for the tips guys. Ill make sure to get one of the roller thrust bearings.
Is this a QA1 specific part?
