Upgrade the suspension on your 2003-2013 Dodge Ram 2500/3500 4WD with the Synergy 8585 Front Upper Control Long Arm Set from GAP. A long-arm suspension upgrade involves using longer control arms that mount further back on the vehicle to reduce suspension angles and bring the truck closer to the stock geometry. The Synergy Front Upper Control Long Arms are adjustable to allow for caster correction and re-centering of the front axle housing for oversize tires and increased ride heights. Our Double Adjuster Assembly allows adjustment of control arm length without removing them from the vehicle and uses a pinch bolt instead of a jam nut for ease of use and reliability. Maintenance Free Dual Durometer Bushings are used at both ends for uncompromised articulation and isolation of Noise, Vibration, and Harshness. When paired with the Synergy Long Arm Brackets (8581) and Synergy Front lower Long Arms (8583-04) you can guarantee unmatched ride quality and off-road capability.
Features:
- Made From High-Quality Crush Resistant 1.75" X .188 Wall 1026 DOM Tubing
- Suspension Components Feature An Abrasion-Resistant Powder Coat Finish For Maximum Durability And Corrosion Resistance
- Synergy Double Adjuster Sleeve & Pinch Bolt Assembly
- Features Synergy Dual Durometer Bushings (DDB) With Teflon Bearing Surface For A Maintenance-Free Design Focusing On Performance, Flex, Longevity, And Ride Quality
- 100% Bolt-On Components Assures An Easy, Trouble-Free Installation With The Use Of Basic Hand Tools

Comprehensive Guide with Practical Insights
Format: Paperback
This is a solid book for understanding the art and science of working with LLMs and other generative AI models. I always struggled with getting the output I was looking for, and wasn't sure how best to "ask" the models for what I wanted. This book did a great job of laying out the strategies and practical guidance to craft the prompts. There were a lot of tips and tricks, but the overall understanding and framework around prompt engineering has been super useful.

A must read!
Format: Paperback
Hands down, the best book on prompt engineering and implementing LLMs. Really enjoyed Michael and James deep dive. Whether you're technical or not, this book is foundational to a deeper understanding in how to properly explore and implement LLMs.

Helpful for GPT/LangChain framework
Format: Paperback
I applaud the authors for putting forth a comprehensive introduction in a rapidly evolving space. I absorbed a lot, helpful as I was developing a prototype — using open source methods.
And that’s where I was disappointed. The LLM and examples are highly adapted to OpenAI’s GPT-x and the bulky LangChain framework, something not obvious until you dig in to the book. Sure, this may be where newbie demand was when the authors began writing. But as the open source models and OpenAI alternatives gain speed (e.g. Llama 3.1, Groq, etc.) this book may quickly need an updated and expanded version to stay relevant.

Good concepts, but uneven depth
Format: Paperback
Some helpful prompt frameworks, but parts felt repetitive and a few sections stayed too high-level for advanced users. Beginners will likely benefit more than experienced practitioners. If you’re new to prompt engineering it’s a decent starting point; if you’re already building structured prompts daily, it may feel light.
