Its innovative design reduces pack thickness and weight while preventing coning under stress, making it perfect for heavy-duty, commercial, and 4WD rebuilds. Equipped with Raybestos' revolutionary X-32 friction material, it delivers enhanced durability and thermal management for superior transmission performance. ## 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. Under U.S. Pat. 6,484,853 B1) ## Features - Significantly reduces clutch pack temperatures - Can reduce the overall thickness and weight of the clutch pack on modern, compact transmissions - Increases torque capacity and reduces core temperatures without increasing pack thickness - Design improvements keep the single-sided pack from coning under high stress - Perfect for every rebuild including commercial, four-wheel drive, fleet and other heavy duty applications ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00J0B18LK | | Best Sellers Rank | #174,181 in Automotive ( See Top 100 in Automotive ) #161 in Powersports Clutches | | Brand Name | Raybestos | | Customer Reviews | 5.0 5.0 out of 5 stars (55) | | Manufacturer | Raybestos Powertrain | | Model | RZP-001 | | Part Number | RZP-001 | ## Product Details - **Brand:** Raybestos - **Manufacturer:** Raybestos Powertrain - **Number of Items:** 1 ## Images ![Powertrain GM 4L60E 3-4 Z-PAK - RZP-001 - Image 1](https://m.media-amazon.com/images/I/81vBXfPWJ3L.jpg) ## 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 https://www.oregonperformancetransmission.com/product/NTP-K51353Z.html **Q: What is the plate thickness for these and are they all the same?** A: Thank you for your question. All RZP-001 plates are custom designed to fit each application as a whole. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/20511799-powertrain-gm-4l60e-3-4-z-pak-rzp-001](https://www.desertcart.us/products/20511799-powertrain-gm-4l60e-3-4-z-pak-rzp-001) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-22*
