034Motorsport Density Line Bump Stops

Engineered Travel. Tuned Control. Superior Comfort:

034Motorsport Density Line Bump Stops are built to address one of the most common issues that comes with lowering a vehicle: the loss of usable suspension travel. When the suspension runs out of room to move, the car’s ability to handle precisely, ride comfortably, and maintain consistent tire contact all start to suffer. These bump stops are specifically designed to restore that performance by providing additional, carefully tuned suspension support. Their progressive characteristics manage impact forces smoothly, offering control and protection that factory or trimmed bump stops simply cannot deliver. The result is a more composed, predictable, and confident driving experience, especially on lowered setups that demand proper suspension geometry and travel management.

Why Suspension Travel Matters:

Lowered vehicles lose valuable suspension travel, which causes the suspension to reach the factory bump stop much sooner than intended. A bump stop is designed by the OEM as a final-stage buffer, essentially a rubber cushion that protects the shock and suspension components from bottoming out during extreme compression. In a stock-height vehicle, it is meant to engage only during hard impacts and serves as a safety and comfort device rather than a primary spring.

When the vehicle is lowered, that engineered clearance is reduced or eliminated. As a result, the shock engages the OEM bump stop far more often and under lighter loads than originally intended. This turns the bump stop into an unintended secondary spring, which restricts suspension movement, reduces the suspension’s ability to absorb bumps, and prevents the tire from maintaining a consistent load. The outcome is a noticeable loss of ride quality, grip, and handling precision.

Lowered on OEM Bump Stops

  • The suspension stops absorbing bumps
  • The tire loses consistent load and grip
  • Handling becomes unpredictable
  • Ride quality becomes harsh and abrupt

Factory bump stops were never engineered for lowered ride heights, and cutting them only amplifies harshness.

Lowered on Density Line Bump Stops

  • Restores usable shock travel on lowered vehicles
  • Keeps the suspension operating in its intended range
  • Improves chassis balance and stability
  • Enhances comfort by allowing the shock, not the bump stop, to manage impacts

Result: A poised, controlled suspension that maintains grip and comfort instead of bottoming out.

Precision‑Tuned Compression Rate:

Factory bump stops are designed for stock ride heights and spring rates, which means they often fall short when a vehicle is lowered. 034Motorsport Density Line Bump Stops are specifically engineered for lowered setups, particularly those running Dynamic+ Lowering Springs. Each bump stop is carefully shaped, sized, and density‑matched to provide a progressive compression profile that acts like a miniature spring and damper. This allows for smooth, comfortable early travel while increasing firmness as the suspension approaches full compression. The result is controlled body motion, predictable handling, and improved ride quality without harshness.

Platform‑Specific Engineering

Every Density Line Bump Stop is designed to match its specific chassis, ensuring optimal suspension performance. By utilizing vehicle-specific shapes and lengths, these bump stops restore suspension geometry and travel to near-factory levels, even after lowering. Their compression rate and progression are tuned to complement Dynamic+ Lowering Springs, maintaining handling balance while providing consistent, predictable performance. The optimized length and compression characteristics ensure the bump stop works seamlessly with the rest of the suspension, completing a fully engineered performance package rather than serving as a generic replacement.

Why Not Just Cut the Factory Bump Stop?

Cutting factory bump stops might seem like an easy fix, and people have been doing it for years. But every shortcut has a cost. Trimming might buy you a little travel, but it ruins the last phase of the carefully tuned suspension travel that keeps your suspension controlled and your ride composed. The result? Harsh bottom-outs, unpredictable handling, and a setup that never feels quite right.

034Motorsport Density Line Bump Stops are the right way to do it. Designed from the ground up for lowered vehicles, they deliver the full range of motion your suspension deserves, with smooth, progressive control that cut OEM stops simply can’t match. More travel, more precision, no compromises.

Human-being ET celebration!
Format: Paperback
What made this book so fascinating and essential to my collection is the amount of Human Being looking humanoid off worlders who have visited our planet…it is so fascinating. Most of the time you hear, simply about the Pleiadians when the word Nordic is brought up. This goes so much further into the diversity of systems out there that human beings exist within. Highly recommended.

An Amazingly Wise Book
Format: Paperback
Trauma, in fact, intergenerational trauma that has not been metabolized, is a recipe for racism. As a psychotherapist with over 50 years addressing trauma and the need for decolonization therapies that go far beyond what is customarily taught in universities, My Grandmother's Hands is the clearest guide I have come across to help suffering individuals "grow up" as Resma Menakem respectfully says. This is a profound, wise, brilliant, compassionate, and exceptionally insightful effort to confront our body's pain as well as that of our families, communities, and our American culture. When we grow as individuals we will also grow as communities -- what Martin Luther King Jr. referred to as "the beloved community."

A must read for therapists and everyone else
Format: Paperback
As a psychologist who works primarily with individuals in marginalized communities, I see a lot of clients who have experienced historical, intergenerational, developmental and ongoing current trauma, often as a result of systems of oppression (racism, sexism, homophobia, transphobia, etc.). I was very excited to dive into training in somatic experiencing (SE), a "bottom up" approach to trauma treatment that recognizes the ways that traumatic experiences get stored in the body, and therefore need to be healed through the body. However, I was disappointed to find that most of the books on SE, as well as the trainings themselves, rarely if ever mention racism or other systems of oppression and the trauma they cause. This was such a disappointment to me, especially given that racial trauma is so prevalent in the everyday lives of my clients and perpetuated daily by the current political climate. Therefore I was thrilled to discover this book. Resmaa Menakem filled in the gap I was feeling in the SE literature, applying somatic experiencing to racial trauma and the ways that racism impacts the bodies of white people, black people (and all people of color), and those who are charged with "serving and protecting" us, the police. This book was a huge eye opener for me. Not only did it give me compassion for my own white body and the ways that trauma has been metabolized and passed on from white folks to POC through the mechanisms of white supremacy, but it gave me new and more embodied ways to understand the lives of people of color and work effectively with my POC clients. It also gave me new compassion for cops, who, through their own trauma responses and the effects of white supremacy, are now more like soldiers whose mission is to control and suppress black and brown bodies. Although I will continue to feel outrage and grief at every unnecessary police killing of an innocent man or woman of color, this book helped me to remember that we are all impacted by centuries of white supremacy conditioning and that cops need and deserve healing around racial trauma too. I highly recommend this book to therapists and healers, especially those who work with individuals in marginalized communities. Each chapter provides exercises to embody the learning in the chapter, so that healing is happening not just from the top down, but from the bottom up. There are exercises for individuals and groups, for white bodies, POC bodies and police bodies. The book is extremely timely and relevant and should be required reading for anyone wanting to understand more about the history and current conditions of racism in America, its impacts, and how to heal.

Think of racism as a moral failing isn’t helpful. Instead, think of it as a trauma response.
Format: Kindle, Format: Kindle
If we are willing to stop and listen to the voices of these people, both in the streets and in their writings (for generations now), we will hear them tell us their experience. And their experience is horrific. Some of us will turn away, finding solace in justifications (“He should have complied!”) or distancing (“My family was poor too. None of my family owned slaves.”) But if we care about a sustainable future for our country, if we have the smallest shred of a sense of responsibility for our neighbor, or if (like me) we claim to follow Jesus, the one who taught us to love our neighbor as ourselves, and to put other people’s lives before our own, then we must listen. In My Grandmother’s Hands, Resmaa Menakem comes to this conversation from a different and very helpful angle. He suggests that three groups are clashing in our country today: black-bodied people, white-bodied people and police. He suggests that the animus, reactivity, and often explosive violence between these groups is in fact the result of unprocessed trauma. He digs deep into the story of each of these groups to demonstrate the primary and secondary trauma each group carries. Then he talks about the process of trauma retention and how, if we fail to understand and process our trauma, we inevitably become less flexible, more reactive, and more violent. He suggests that the solution to our problem is not solely in education, awareness or even new policies, but in becoming more aware of our bodies, learning how to handle and process trauma, and becoming more resilient in our interactions with other traumatized people. This is the first book about racial injustice that I’ve read where I finished feeling like I could actually make a difference. I’m not a policy maker. I’m not able to be a regular front-line activist. I don’t have piles of money to spend at Black-owned businesses. It’s easy to feel like my small contribution can’t possibly make a real difference. But Menakem suggests a path that any one of us can walk--coming to terms with our own experience of racialized trauma -- and this will open up the path for other ways we can be a part of creating a more just, compassionate, and equal society.

Enlightening, transformative, maybe even life-changing
Format: Paperback
I would have to say that this is an interactive book. As I was reading this with a group, reading one or two chapters at a time, it was possible to do all the exercises. I did not do them all, but must say it was an eye-opening experience. The basis premise of the book is that we carry trauma in our bodies, and that we respond to issues of race, first and foremost, in our bodies, as a visceral response. And, as so many of our experiences originate early in life, these responses are often immediate and unconscious, and thus, this book requires a great deal of interior work. It's worth every moment of it. I remember clearly, that before I had finished the introduction, I felt rage- actual rage. And for a person who considers herself balanced and rather low-key this was quite astounding. And this rage continued to surface. Let me just say that this book makes you explore unexamined parts of yourself, if you will let it. Expect to feel uncomfortable, and if you push through it, you may be different when you get to the other side...
