Just the right hight

I have a staggered set of 20-in wheels on my Camry. I need it to lift the back because every time I hit a bump or if I had people riding with me my tires would rub real bad. These blocks are a lifesaver and lifted the rear just enough. I also have the coil spacers in place

Item does as it is described

Install was easy. Wrap a zip tie around the block and the spring so it doesnt come off.

Instalation sur un honda ridgeline 2022 tres bon produit

perfect for our use

This product did as advertised and works great

Easy to install works great

Easy to install works great

Very satisfied

I bought these as “help springs”. I had bought another brand that cost 200.00 for a pair. These far exceed the more expensive brand. They are much easier to install, they improve the ride, and they gave a slight lift to my truck.

Works great

Working good so far. They have not fallen out by using zip ties

Rubber block

It's a block! It's rubber! It shimmed up what I needed shimmed up! Yay, I recommend for shimming!

Good gift

Great my husband loved them!

Excelente

Muy buen producto recomendado

👍

Works freakn great!

Use 3 zip ties to help rubbershox from falling off

Good so far.

Does the job!!!

Product worked as it said it would.

Good Firm Blocks

I combined these with spring buffers to level my jeep 1 inch in the front and dampening the coil springs. Together I achieved exactly the look and ride I was seeking.

Seem to be working.

I gave this product a five star rating because at the present, being on the car only two days and test driving it a couple of times, they seem to be working well. time will tell. Hard to really rate a product like this when it is this new.

Easy to work with and does the job

I installed on a 2wd dodge with a mushy front end coil spring. Installed and zip tied in. Notice a big difference immediately in just stiffness. Is the rubber worth the price? If not, the ride improvement sure as heck is. Great product.

Great costumer support

I got a pair of this to install in my 2013 kia soul,so I can carry 4 bikes on a hitch rack,they worked great until they fell off, contacted the company and they sent me a replacement right away and gave me new instructions so never lost it again,it was easy if I would it know, (Drill a hole on a corner and use a zip tie in case it falls don't get lost.Rick E. From rubbershox took care of me ,can't beat great costumer service !!Thank you great company!!

Still working well

They created the perfect ride height for my car without sacrificing the ride quality.

Problem solved!

I have previously installed a stacked set of the robbershox coil spring collars to keep my tires from rubbing on the fenders on big/hard bumps, but after time, the two top ones deformed because they were too close to the top of the strut and they got squashed. I removed those, left the middle collars in place and installed the rubberblox at the bottom of the coild wedged in between the coil spring and the strut housing and this worked perfectly. Not only did it completely stop my tires from rubbing, but it gave me a slight lift for better tire overall clearance inside the fenderwell. The combination of the collar and the blocks works really well!
