Is the wrap to keep the battery warmer, or to help protect it from the heat of the engine? Heat kills batteries more than cold does. With cold they don't hold a charge as well but with heat they break down more quickly.

Torsion keys are not necessary to lift the front end of the H3. All you need to do is turn the torsion bars via the bolt at the aft end of the torsion bar and set it to whatever height you want. Please be careful as putting too much height in the front end can destroy CV axles and steering racks.

The ride is the same whether spring over or under. The front was lifted with a Rancho lift kit. Unless you have a Rancho, do a custom lift or do a SAS, it doesn't make sense to do a spring over in the back.

The other thing to consider, and I hate saying this, is that the forum traffic is way down and you have a limited audience here. You may need to consider other marketing and research efforts like FB. (Ugh). You will likely get a lot more interest.

You did put out a good idea but members here also put out good ideas and concerns. $6500 might be a good value in today's market but it's still a challenging concept to accept knowing they were much less a while ago. Charging $5000 for new old stock was considered a ripoff not too long ago. Yes...

I used compressed air. Went perfect on the first one and didn’t work well on the second one. Thought I had a grip on the tube on the second one and it still slipped off. Can work well if you are careful, and these other ideas are great as well

That's what I did. I requested a 1.5" lift with my rear spring re-arch. I am still using my original leafs after 194,000 miles with that one re-arch done on them.

Can't help on the specifics, sorry. Haven't heard of this issue before.

Yes, a spring over is possible and gives you a bunch of lift - too much unless you lift the front end as well with a lift kit. Cranking the torsion bars or adding torsion bar keys won't suffice. If the rear end is sagging consider finding a quality spring shop and getting them rearched. I did...

The H3 doesn't have a knee bolster. But it does appear to be related to passenger presence B0013 stage 2 or B0017 stage 1 The passenger instrument panel air bag stage 1 or stage 2 high circuit is less than 2.4 volts and the passenger instrument panel air bag stage 1 or stage 2 deployment loop...

Goodyear purchased Cooper in 2021

I had the rear springs re-arched at Valley Spring Service on Jefferson St. in Phoenix. They've held up really well.

If I recall correctly, all he did was move the lower mounting put up. The top mount is unchanged.

I should add that I have a spring over and not Rancho shocks. Also, Reloader built perches so that the bump stops would be part of the suspension travel as GM designed. There are witness marks on the perches from the bump stops.

Welcome to H4O!

Wait, I'm a loud mouthed know-it-all but I really don't have any minions, so I guess this is a better place. Glad you're here and that you could find such an easy fix to make your H3 great again. Really clean looking truck!

I left mine in there - actually, I replaced them since they were old and tired (like me). They certainly aren't going to hurt and they could help

Whoa! Doc, great to see you! Hope all is well with you.

I have one of these on my firewall with a connection straight to the battery, and relays as needed. Of course that implies a more complete wiring job but your in-cab switch doesn't need permanent mounting yet. I tapped into the 12V lines for the accessory outlets for my lockers. Those outlets...
