Installing Eibachs New Pro-UTV Spring And Performance Stabilizer Bar System
Springtime For Hitting And G-Outs
Long known for their performance springs, Eibach has been making race vehicles handle better for 50 years. In that time, their products have been on vehicles that have won at disciplines from Formula 1 to Baja.
Tuning suspension is as much an art as science, but that science is as steady as mathematics. Taking known parameters such as weight times force times angles and working out a formula is best left to the experts. Luckily, companies such as Eibach are the experts when it comes to spring rates and how they affect shock performance and therefore the performance of your ride.
Recently Eibach has turned its eye toward UTVs with their Pro-UTV spring and antisway bar systems. Eibach produces their kits for the Polaris RZR XP1000 and XP Turbos, Cam-Am Mavericks, and the Yamaha YXZ 1000R. The YXZ’s come stock with high-quality and multi-adjustable Fox Podium X2 shocks, so there’s no problem there, but fiddling with the clickers on shocks are just one aspect of fine-tuning a performance suspension. Getting the correct spring rate for what you’ll be doing is just as important. The best part is swapping out springs is fairly easy.
It was on a YXZ SS that we watched as they swapped out the stock springs and antisway bars for their new Pro-UTV units. The Eibach kits come in Stage 1, Stage 2, and Stage 3. The Stage 1 is simply a stock replacement (and really, who wants stock?). The Stage 2 have a stiffer spring rate than stock and are designed for two- and four-seat vehicles that will be rode hard, while the Stage 3 are stiffer still and are for vehicles that will have things such as spare tire racks, jacks, spare fuel, and other items that add weight to the stock vehicle. They’re perfect for racing and hard driving with things that you’ll need to do those long distance treks.
One Wednesday each month the Eibach guys are in Barstow to help customers dial in their vehicles. They will install springs, check things like ride height, and generally help to make your car, truck or UTV handle better, soak up the bumps better and generally go faster. It was there (in a howling wind!) that the Eibach crew installed their kit onto this YXZ. We noticed a difference immediately.
They put the suspension back to totally stock settings, and we’d run the Yamaha up and down the roads and rutted racecourse that is “Barstow Main.” The stock rearend did kick up but the Eibach-equipped YXZ didn’t. It was faster and more controlled through the whoops than the stock setup. It also stayed straighter than before when attacking those whoops.
The other pieces of the Eibach puzzle are the Pro-UTV Performance Stabilizer Bars. They are also stiffer than stock and are, of course engineered to work with the new springs. They have multiple end-link attachment points to allow further fine-tuning of the suspension action. We found that they reduce body roll and keep the YXZ level even through hard turns in sandy conditions.
The combination of the Pro-UTV springs and antisway bars gave the Yamaha a much more controlled feel in virtually every condition. We could push harder than before with more confidence and less concern for those hits we didn’t see coming.
Follow along as Eibach installed their new Pro-UTV system and see how easy it can be to get your UTV to work better, go faster and generally be more fun to drive.
While Eibach is a German company, they do produce springs here in the USA at their Corona, California, manufacturing facility. They do it all as rolls of wire come in one side of the building and come out the other end as springs. The process is fascinating to watch, so we thought we’d show you what we saw.
