This is the Werks 34mm "Heavy" Pro Clutch 4 Shoe Racing Clutch System. Clutch tuning is one of the most important aspects of 1/8 scale nitro racing. No one likes to disassemble their clutch to change the shoes or springs, but changing track conditions over the course of a race day make clutch tuning a skill that racers must develop to put themselves at the top of the podium. A system that simplifies this task is something that racers and bashers have been begging for. Werks Racing has once again stepped up to the plate to provide you with the tools you need to lead, with the “Pro Clutch”; a clutch system that not only offers the ultimate in simplicity, but also incredible lifespan and flexibility!
The "Pro Clutch" uses a proven system for the easiest possible assembly and removal. The shoes and springs are installed by sliding them over the flywheel pins, then the top plate slides on and with a 1/4 turn twist to load the springs you are done! It takes 10-15 seconds to assemble the complete clutch! As an added bonus the clutch does not need to be disassembled when it is removed from the engine. Simply remove the clutch nut, and pull it off the crank! This design allows you to store a pre-assembled clutch in your pit box for a quick swap of the entire clutch. This system becomes a powerful tuning option when you take advantage of the different weight flywheels!
The "Pro Clutch" is offered in three different flywheel weights, and each weight is available in both 32mm and 34mm diameters, allowing you to choose the flywheel that best suits your needs. This is useful in that it allows you to keep multiple clutches on hand in different weights to tune for different track conditions. There are two different Steel flywheels: heavy and medium. These can be used to tune for low traction surfaces, as well as to smooth out low RPM power delivery on engines that have a strong bottom end hit. There is also a super lightweight Aluminum flywheel that can be used on high traction surfaces and to provide a little extra bottom end snap from your engine.
The Werks Pro Clutch includes a set of four "Long Life" aluminum clutch shoes that have been proven to outlast the competition, as well as a complete set of 0.9mm, 1.0mm & 1.1mm springs to tune the engagement point of the clutch. Additionally, super hard clutch pins are also standard, making notching and clutch pin wear a thing of the past. The flywheel also has a special coating that not only provides a bit of "bling", but also a slippery, non stick finish that significantly reduces the likelihood of gunk or debris getting stuck on the flywheel under the clutch shoes causing them to hang up.
The new Werks "Pro Clutch" system provides a greater level of tunability, incredible performance and ease of assembly that has no rival! Get Werks, or get worked!
