I pulled my G16 driven clutch and will replace the sliding sheave, spring, ramp shoes and belt. Should I also replace the fixed sheave or will it make a difference at all. My clutch has the typical growl and the ramp shoes and sliding sheave are well worn but I don't want to throw money at it that isn't needed. Also, my cart has a basic 4" lift kit and 18" know by tires. Is the Jakes power clutch kit the way to go for more low end torque or is a stock spring in the correct holes (C4?) work just as good? Thanks for any info

The sliding sheave helps adjust the clutch’s engagement and provides smooth operation as the belt moves. If it’s worn, it can cause poor clutch performance and increased noise which is why replacing it is a smart move. The ramp shoes are responsible for transferring the power from the spring to the sliding sheave and if worn out they can lead to inefficient power transfer and that typical growl you’re hearing.
The spring inside the clutch controls the clutch engagement point and the amount of pressure applied to the ramp shoes. A worn or weak spring can affect the clutch's ability to engage properly leading to sluggish performance or poor acceleration. Similarly, the belt which connects the engine to the drive system can stretch or wear out over time affecting the clutch's ability to transfer power efficiently.
As for the fixed sheave, that's the component that stays stationary and works with the sliding sheave to manage the belt's position. If it’s worn or damaged, it can cause misalignment resulting in reduced performance and increased noise. If it shows significant wear or damage, replacing it could help restore proper clutch function.
Regarding improving low end torque, experimenting with a belt that’s 1 inch shorter could help. A shorter belt increases the clutch’s engagement RPM, which can enhance torque by allowing the clutch to engage more aggressively. This adjustment can provide better acceleration and improved performance at lower speeds. The Jakes power clutch kit is designed specifically to enhance low end torque, but if you’re looking to manage costs starting with the shorter belt might be a cost effective way to achieve similar improvements.
