Usa Spring kits - Eibach vs Shock Therapy vs ???

Looking for some input.

I have a 2016 RZR XP 1000 with approx. 350 miles on it. I've added quite a bit of weight (front and rear bumpers, rock sliders, winch, roof with 6 speaker sound system). I do mostly woods riding with a mix of hill climbing and rocks (KY and TN mostly)

My tender springs are basically completely compressed. I'm looking for a kit that will bring back stock riding height (a little extra wouldn't hurt).

I'm getting very close to pulling the trigger on the Shock Therapy stage 4 spring kit ($900) but I've also heard good things about the Eibach.

I want everyone's opinion on the best spring kit and why.

Thanks in advance for your feedback

They use the same springs I'm pretty sure

I don't have any experience with the Eibach springs, but I recently installed the Shock Therapy kit and i am extremely happy with them.

Another vote for Eibach. I am running their stage 3 rates on my 4 seater.

I'm looking for the best bang for my buck. After much reading it seems a spring change does a lot for the XP1K. I'm not a racer so I don't need the very best suspension but I would like to gain a little clearance without compromising the ride.

Eibach sounds very interesting but I'm a little concerned that their stage 2 kit doesn't come with stiff enough springs for all the weight I've added. Their stage 3 kit with heavier springs is only offered for the 4 seat ZRZ.

Stock 2 seat rates
Front: 169/215 for a combined rate of 95 lbs/in
Rear: 109/204 for a combined rate of 71 lbs/in

Eibach Stage 1 rates
Front: 150/200 for a combined rate of 86 lbs/in
Rear: 100/200 for a combined rate of 67 lbs/in

Eibach Stage 2 rates
Front: 200/250 for a combined rate of 111 lbs/in
Rear: 150/300 for a combined rate of 100 lbs/in

As you can see the Stage 1 rates are very close to stock and the Stage 3 rates are quite a bit heavier which will be much better suited for adding weight to your RZR.

The formula for combined rate is Spring1 x Spring2 / Spring1 + Spring2

I put the stage 3 for the 4 seater on my 2 seater 16 xp1k for that reason. I don't have cage and bumpers yet but feels good right now. At windrock I felt it was nice and had a 200 lb toolbox in the bed.

I don't think Eibach offers the stage 3 for the XP1K. I can only find it for the 4 seat XP 1000. Or will the designated 4 seat version fit the 2 seat XP 1000?

So I see a crossover, the billet retainer, and springs. Do you revalve as well? What about service after the sale? I'm all for the new guy starting up, but you have to bring a great product and better customer service. Not knocking you at all, just trying to see what you offer. PM me if you would like.

Yes, I have the 4 seater stage 3 on my 2 seater XP1K. Look at my posts I found this kit for 640 and posted the link in the 4 seater section.

EDIT: SummitRacing was at 640 a month ago, now they raised the price up to 777.
