## Overview

The Raybestos Powertrain GM 4L60E 3-4 Z-PAK is a patented single-sided clutch system engineered to reduce heat and weight while increasing torque capacity by up to 30% over OEM. Designed to prevent coning under high stress, it’s the ultimate upgrade for modern compact transmissions, ideal for commercial, fleet, and high-performance rebuilds.

## Description

Z Pak is the patented, single-sided clutch system that outperforms OE in torque and heat capacity without coning. For new OEM platforms, the Z Pak design can reduce the overall size of the clutch pack for a smaller, lighter assembly with greater thermal capacity. On existing designs, the single-sided plate can increase torque capacity and reduce core temperatures for a significant reduction in hot spotting and greater clutch life. And Z Pak takes the heat without coning. When used with the revolutionary X-32 friction material developed by Raybestos, the Z Pak system outperforms OE by as much as 30%. (*Mfg.

Review: 4L60E Z-Pak - Great item. Straight forward instructions
Review: I want am the cool new tech stuff with this one - Everything I expected them to be maybe even more ! I just received the rest of my Alto Red Eagle clutches, reveres input ,direct ,over run and low/reverse outputs, still waiting for my output shaft / tail housing and five gear planetary gear sets. I am so anxious to get this trans together along with the 565 CID Chevy engine up and running for my fully customizes stretched front shortened box tube frame pro street 96 Silverado with Lincoln Navigator IRS/ Mustang 2 front. This will my sixth race project car and my most elaborate build yet. I want am the cool new tech stuff with this one. All electric doors, ABS, Cruise control, AC , Air Bags Killer stereo, Edelbrock Proflo XT 3 with 80 lb/hr nozzles, maybe even a heavy shot of nitrous. I'm dubious about the 4L60 being up to this ,but no worries. Once it's all done, and more trans appears to be in order, You'll hear cfrom me again for 4L80 parts. The 60 will find a new home.

## Questions & Answers

**Q: Hi what is the different between 700r4 and rzp-001**
A: 700r4 is a transmission designation. Rzp-001 is a part number for a component inside a 1988-up 4L60/E/65E/70E

**Q: Will this work in my 1995 corvette 4l60e**
A: Yes it should work on any 4l60/e from early 90s thru to current. Definite must have for any 4l60 the 3-4 clutch is very high failure point. Just be sure to follow the instructions to carefully be sure clutch clearance is within what they want.

**Q: Will this kit fit a 2004 4l60E? I know it says 88 & up but most kits go to 2003. Thanks!**
A: It fits all the way back to 82, it even fits the 700R4
