Ahhh, so that’s how Paul ended up with a new RZR, he bought it “for her!” (hehehe) I’d have tried that but mine refused to give up her handlebars.
After following this question/dilemma around on the forums I have to agree with Paul. If the ground stays were it is, tire size doesn’t change and you end up with 2 or 3 more inches between your chassis and the ground, whether your lift hardware is installed at the top or bottom of the shock it doesn’t matter, the increased angle on your axles will be the same. Suspension/handling characteristics may differ but axle angle has to be the same.
That said, for some reason there are definitely inconsistent reports of who experiences CV binding and who doesn’t. It seems you can take two RZRs of the same year, install the same lift kit on them, one machine will bind and one will not. No one I’m aware of has approached this problem scientifically to establish whether there’s a variable in suspension geometry, CV construction or just shock setting that’s behind this inconsistency.
On my ’08 RD’s 2” kit only offered just over 1” of lift. This was calculated between the same points of an empty machine and my workbench with the machine rolled off and back on between measurements, not just coming down off a jack after the install. Back then I wasn’t really looking for CV bind so I can't say whether it did or didn't. I didn’t notice any difference in the machine’s performance or handling between before and after the installation.
Not being satisfied with this amount of lift I tried Xtreem’s 3” lift, which only offered 1.5” of actually lift measured under the same conditions. However, while I like the approach Xtreem takes to upper shock mount relocation the kit requires preloading the front springs with large aluminum spacers. In my opinion this ruined the machine’s front suspension characteristics. It felt like the thing was going to throw me out on “bumpy” terrain; the ride was brutal.
So I took out the spring spacers but left in the rest of the kit and reinstalled RD’s 2” kit at the bottom shock mounts. By simple math one might conclude with both a 2” lift and a 3” lift installed the result might have been….(lets see, um, carry the one…….) oh yeah, 5”. Especially in the rear where both lifts were installed without modification (except lengthening the sway bar links). Nope, with both lifts I ended up with 2.25” inches of lift, less than half.
But this hybrid experiment worked. I achieved my desired amount of lift and maintained handling characteristics very close to stock although as you can imagine, with a true 2”+ of lift the fly in the ointment was CV bind, both front and rear with the suspension uncompressed. I chose to remedy this with limit straps, which presented another learning curve.
After carefully calculating distances that would prevent bind between chosen mounting points I ordered the correct length straps, or so I thought. It turns out the accepted “stretch” for limit straps is about 1.5” per foot. My fronts were 15” and rears were 18” so stretch of over 1.5” per strap let the axles drop below my maximum specs resulting in bind. Damn! Ordering and installing new straps an inch shorter cured the problem but what a lot of work to end up (safely) with a couple inches of lift!
When I did this last year there weren’t as many lift choices on the market as there are today. For a quality straightforward product that installs easily and is reliably designed and built, of the two I tried Rubberdown’s definitely gets my vote. Apparently true lift results, as well as CV bind, may vary.
