PEFI Adjustable Clutch Ramp & Weight Kit

P-Drive | 900 ACE Turbo R & Mach Z

Take complete control of your clutch calibration with the Precision EFI Adjustable Clutch Ramp Kit, engineered for the P-Drive clutch found on the 900 ACE Turbo R and Mach Z.

Unlike fixed-weight clutch ramps, the PEFI system allows you to fine-tune clutch weight without removing the clutch from the sled, making RPM adjustments faster and easier whether you're in the shop or out on the trail.

Designed to deliver consistent clutch performance across a wide range of power levels, these ramps work exceptionally well on stock sleds and support applications producing up to 250 horsepower.

Why Choose PEFI Adjustable Ramps?

Proper clutch calibration is critical to maximizing acceleration, belt life, and engine performance. Maintaining the correct operating RPM ensures your engine remains in its peak powerband, regardless of changing riding conditions.

With the PEFI Adjustable Ramp Kit, you can quickly compensate for variations caused by:

• Snow conditions
• Temperature
• Elevation
• Rider weight
• Performance modifications
• Different clutch calibrations

Simply adjust the removable weight inserts to dial in the exact RPM your setup requires—without removing the clutch.

Features

• Adjustable weight system for precise RPM tuning
• Weight changes can be performed without removing the clutch
• Precision-machined and hardened steel construction
• Black and clear zinc coating for superior corrosion resistance
• Designed for exceptional durability and long service life
• Compatible with stock engines and performance builds up to 250 HP

Stage 1+ Specific Design

The Stage 1+ version of these ramps is manufactured with a heavier base profile than our standard 900 ACE Turbo and 900 ACE Turbo R ramps, providing the ideal starting point for higher-output applications.

Every Precision EFI clutch ramp kit includes our adjustable weight insert system, allowing you to fine-tune clutch calibration for your specific setup.

Need Additional Weight?

Additional weight inserts are available separately if you already own:

• Precision EFI 900 ACE Turbo adjustable ramps
• Precision EFI 900 ACE Turbo R (No Flash) adjustable ramps

This allows you to expand the adjustment range without purchasing an entirely new ramp kit.
