ZZP progressive bump stops are a great addition to any of our ZZP Coilover kits, or any other coilover kit on the market. Standard bump stops that come with coilover kits are small and hard, which is fine for the street and allows for full travel of the damper; however, when pushing the car on road course, autocross, or winding roads those hard bump stops can cause upsetting suspension behavior when you hit the bump stop. 

Our progressive bump stops are made of a durable material that ramps up the stiffness/rate as they are compressed. While they are taller than standard coilover bump stops, the rate begins much softer and increases as the car puts weight over a corner. These are a must for anyone looking to go fast turning corners in a ZZP platform vehicle, or any other car you may own.

These bump stops come in two different sizes. The size you are choosing is the inner diameter of the bump stop. Most of our coilovers use a 20mm front shaft, our 3800 rear coilovers use also use a 20mm rear shaft. Our Cobalt/Ion rear dampers, ATS/Camaro rear, Sonic/Cruze rear, Slingshot (full kit), and Kappa coilovers (full kit) use a 12.5mm shaft. If you have any questions regarding what size to order email customerservice@zzperformance.com.

Sold individually. If you want to replace all 4 of your bump stops you will need a quantity of 4. 

Note: Due to the increased outer diameter you may not be able to use your stock coilover dust boots with these bump stops. Not recommended for stock strut style suspension. Coilover not included.

These things are amazing, these are a must have for your coilovers, if you don't have them get them. It made a night and day difference, I would even go as far to say they have a stock feel to them now. No more rough jarring and jolting when you hit bumps. It also has helped in my driving performance for autocross, I put them on on a Friday (as soon as I got them) and ran the dog **** out of them Saturday, even hitting some pretty rough surfaces and large bumps, they held up. Another great quality product from ZZP.
