If you’re looking to up your clutch game, the ACT HD-M/Race Sprung 4 Pad Kit SB9-HDG4 is a solid choice. This kit packs in ACT's Heavy Duty pressure plate, which is known for its durability. The special diaphragm design boosts clamp load, cuts down on deflection, and helps your clutch last longer. Plus, they put their diaphragms through a four-stage heat treatment, so you know they can handle the heat. The pressure plate is built with precision cover stampings, giving it the rigidity and consistency you want when you’re pushing your ride to the limit.

Now, let’s talk about the 4-pad spring-centered race disc. It’s designed to dampen those annoying torsional vibrations, making for a quieter drive, and it’s tough enough to withstand some serious abuse. The spring retainers have wraparound spring windows and thicker stampings, which means they support the springs better and reduce stress points—so you can shift with confidence, even when the going gets tough. Just a heads-up, with this setup, engagement is a bit harsher, but that means you’ll be shifting quicker, which is a plus for spirited driving.

Also, the Monoloc feature is a game changer. It replaces the standard two-piece wedge collar and wire ring found in pull-type clutches with a one-piece design. This means better alignment and a more consistent feel, no matter how you drive. Constructed from hardened Chrome-moly steel, you’re looking at a clutch that’s built to last.
