Product Details

The SPEC SF334-4 Stage 4 Clutch Kit is a race-grade, solid-hub performance clutch designed for drivers who demand maximum torque capacity and durability. Built as a step up from the Stage 3, this kit replaces the sprung hub with a solid 8-rivet hub assembly that is heat-treated for exceptional strength under high-stress racing conditions.

This kit is offered in a 4-puck configuration, striking an ideal balance between the lightweight 3-puck and the smoother-engaging 6-puck variants. The rigid solid hub design makes this clutch best suited for dedicated performance and motorsport applications. While the 6-puck version is marginally street-drivable, the solid hub design is not street-friendly and is purpose-built for competition use.

Key Features:

  • Solid 8-rivet hub — heat-treated for maximum strength and durability
  • High-clamp pressure plate — delivers increased clamping force over stock
  • Carbon-graphite friction material — proven in aggressive motorsport environments
  • High-torque solid hub and disc assembly — engineered for maximum power transfer
  • Bearing and tool kit included — everything needed for installation
  • 4-puck disc configuration — optimal compromise between weight and engagement smoothness
  • Available separately in 3-puck and 6-puck configurations

Ideal Applications:

  • Drag Racing
  • Road Racing
  • Rally / Rallye
  • Drifting
  • Pulling

SPEC Clutch manufactures its products in-house using advanced fabrication processes and strict tolerances, ensuring consistent quality across every kit. The SF334-4 is part of SPEC's race-oriented Stage 4 lineup — a performance step beyond street-focused stages and engineered specifically for the demands of competitive motorsport.

Item was exactly as described and was delivered on time Friday after ordering it on Wednesday. Great job! Thanks.

Had the product I needed at a price that couldn't be beat. The shipping was a little high, but not completely out of line, either, and it was still better than other companies who have even MORE ridiculous shipping rates. Will buy from them in the future if they have what I need.

So far so good.

Fast and easy transaction.

Autoplicity had the lowest list prices I could find anywhere for KC hilites! I was only going to get one pair, but the price was so good, I bought two! Shipping wasn't free and that's my only complaint. Regardless, it was only 12 dollars for a 300 and some-odd dollar order. Shipped in 3 days; should arrive soon!!!

All was good,except delivery wait time..it was longer than usual and delayed from the 8th to the 10th.

Awsome website! Very easy to use and I really like the option to use Paypal for my order.

Thank you ! Easy

Good price for great name brand car parts. AEM fuel filter very low price and new. Hope the shipping is as great as the price. :)

Very Good.

VERY GOOD

First experience so we'll see. So far it has been easy.

Helpful-reasonable prices-reasonable shipping-prompt.
