Description
Evolution Powersports is setting new standards for durability, reliability, and power out of a CVT drive belt. Regardless of where you ride or how much horsepower your vehicle has, EVP Alpha Drive Belts reimagine what’s expected from a UTV performance belt.
Durability comes from a newly blended synthetic rubber with advanced cord technology, as well as belt face angles that are precision machined to extremely strict specs. The compound, cord materials and finish are the keys to Alpha Drive Belts’ strength and performance. In total, EVP tested six different compounds. Although all were superior to anything else on the market, the one we selected stood out among the rest.
We tested Alpha belts under a variety of conditions and horsepower levels (including stock) throughout the demanding testing and development phases. This included countless Mainline Dyno pulls on 600+ horsepower machines to simulate the absolute harshest conditions these belts would ever encounter. Additional testing was performed in the grueling BITD Vegas to Reno endurance race where EVP racers ran the entire race without failure. Not only did the Alpha Belt last up to TWO TIMES the life of OEM and other baseline competitors on the Mainline, but it also posted the lowest belt temperatures we’ve ever seen during a desert race.
We have short course racers that now go from the dyno to qualifying to race and do not change belts. Prior to Alpha, racers would typically require three belts – one for the dyno, one for practice/qualifying, and one for each race.
In addition to strength, the Alpha Belt consistently showed the highest horsepower runs vs OEM or any of the other compounds we tested. On average, it was 10-12 WHP more than any other belt. More engine power was being transmitted to the hubs and less was being wasted in slippage and heat – it was clear early on Alpha Belts were an absolute game changer for putting power to the driveline.
Drive Belt Installation/Break-In Procedure
Step 1: Wash your new belt in warm soapy water (recommended Dawn Dish Soap) and let it air dry
to remove all residues during the manufacturing process.
Step 2: With a green Scotch-Brite pad, crosshatch both primary and secondary clutch sheaves. This
will clean up the surfaces on the sheaves and advance belt grip.
Step 3: With a clean towel and brake cleaner, wipe down both the primary and secondary inside
sheaves. This will make sure the clutch surfaces are clean of any brake dust from previous belts.
Step 4: Install the CVT drive belt so you can read the writing on the belt from the outside of the car
looking into the clutch box. Once the belt is on both primary and secondary clutches, remove the belt
clutch tool and spin the secondary until the belt is seated.
Step 5: The last and final step with our drive belt break-in procedure is key. Install the new belt and
drive in low gear for the first 15-20 miles. “Take it easy”- no high-speed runs, no hard launches, vary
the speed. This will ensure the new belt “seats” properly into the clutch sheaves.
NOTE: Once a belt starts to slip and gets overheated, the material becomes harder and loses its
ability to grip the clutches effectively. The longer you keep things clean and allow your belt to grip
without slipping, the longer your belt is going to provide service to you.
