I'll measure them tonight and let you know.

I used the VS800 Intruder in Progressive's application finder.  For the 412 series shocks, they list the following:

Standard 11"
412-4233C

Standard 11.5"
412-4201C

Standard 12"
412-4228C

Standard 12.5"
412-4207C

Heavy Duty 11.5"
412-4236C

Heavy Duty 12"
412-4238C

Heavy Duty 12.5"
412-4214C

The last is the set I bought.

What is the travel on these shocks versus the stock ones?

I'd like more travel with the same load over that distance.  Not just taller or stiffer, but taller and the same load rating.  Thereby, a more cushioned ride without bottoming.  Is that what we are talking about?

Thanks.

That is it - eliminate the bottom out of the stock shocks which happens quite a bit and sends the impact to the seat.

It takes a much higher load on these progressive shocks/springs for the last inch of travel so even with the same length bottom out is less likely.

In reading the stats on these models they seem to be the same shock body ~11" with ~2" of travel and every inch over 11 adds about an inch.

Lancer - the lift is going to be more than that, in all these models the initial compression of the shock due to the weight of the bike and the rider is less because of the stiffer spring.

I was refering to the "unloaded" height of the bikes rear when a different length shock is installed.

Hi Rob;
I can't help but think your bike is too high in the rear with those extended shocks, especially if it effects your sight glass. I see you opted for the heavy duty springs as well. Do you see that as a good choice? Can you adjust for sag with the shocks in the softest setting? How many preload settings are there on the Progressive shocks and what setting do you  find best? If you set them to the stiffest position does the rear wheel chatter when brake skidding the rear tire? Like yourself Rob I too am looking to upgrade my suspension and any help you can provide would be super.

Been on the fence too long on this one - I'm going to toss a coin and order in the 11" shocks today - looking for about the stock rear height - either model 412-4233c (115/155lb) or leaning toward the 412-4232c (90/130lb) both have the same travel and the 90lbs is about stock spring strength and 130lb should slow it down before bottom.

Say Reelthing, let us know how the new shocks work for you when you get them mounted. It sounds like the 90/130 spring rate is the closest match for a Savage offered by Progressive. Do you use a 140/90 15 rear tire and do you currently have any tire interference problems?

I think there are five settings; I don't remember.  I have mine on the lowest/softest preset.  The regular shocks would probably be just fine.  I just figured that being 200 lbs, the heavy duty couldn't hurt.  They are probably a tad stiiffer but I don't have another set to compare them to.  I got the 12.5" set since Babbalou had done so well with his.  I actually like the extra clearance but do need to alter the incline to check the oil.  If I were doing it over, I'd probably opt for the 11" or 11.5" versions.  I knew my stockers were 10.5" and I figured a 2" longer shock might raise the rear of the bike 1" or 1.5" at most.  It's weird how simple geometry didn't seem to apply though and 2" at an angle raised the bike by almost 4".
