On 8/27/2026 Sarvar had this to say:
Professional and honest

On 7/21/2026 T R had this to say:
In 2021 brought my Class C RV to them to have a alignment and they made my E450 drive like a dream. A good alignment with some very specific settings make a WORLD of difference. Hard to find a place that knows what to do. 35,000 miles later the back was sagging so they rebuilt the leave springs and added 1400lbs of capacity which will take out the sag and really help when towing. I should have done this when they had it the first time. Price was very reasonable for the work they did.

On 5/7/2026 Todd Colegrove had this to say:
Needed an alignment for my RV. It is difficult locating anywhere to do work on an RV. They were very welcoming and were able to get it scheduled right away.

On 4/11/2026 Paul Barwan had this to say:
Great communication, freindly, informative and right on time for completion! I took my 40 ft RV in for alignment and work on the air suspension. This old girl has never steered straighter or rode more level. Being a 25 year ASE certified mechanic i dont usually take my cars in but my valencia is huge and cant do that work at home, Joliet suspension did not dissappoint at all. They fixed it the way i would have done it and for a great price! Couldnt be happier with them knowing what a ripoff most shops are....it was a breath of fresh air to find a shop that earned MY trust. Thanks guys....yer all awesome

I have a single cab Ram 3500 dually, they did awesome on the alignment and were fast and affordable.
