ReadyLIFT Tubular Upper Control Arm Kit, full kit on a studio background: two black tubular upper control arms with ball joints on a white background

Arms built for lift

Factory upper arms are designed for stock height. ReadyLIFT arms correct the ball joint angle for a leveled or lifted front end, adding alignment range and strength.

Leveling Kits by ReadyLIFT: Close-up of control arm bushings and a black tubular arm end on white.

Finish the front end

For a vehicle already leveled or lifted, a pair of upper arms is the upgrade that squares away alignment and adds strength.

Frequently Asked Questions

Straight answers on specs, fit and support

Why replace upper control arms on a lifted vehicle?

Leveling or lifting changes the ball joint angle at the top of the knuckle. Arms with a corrected angle bring alignment back into range and relieve the joint.

Do I need a lift kit to use these arms?

They are meant for leveled or lifted vehicles within the lift range ReadyLIFT lists for each part. Check the title and fitment on this page.

Are ball joints included?

Yes. Each pair comes with ReadyLIFT heavy-duty ball joints installed.

Will I need an alignment after installing it?

Yes, plan on one. ReadyLIFT notes the vehicle may need an alignment after installation, and headlamp aim should be checked at the same visit.

Does it affect driver-assistance cameras and radar?

Changing ride height can shift camera, radar and sonar aim. ReadyLIFT says to check and recalibrate these systems after installation, and some vehicles need dealer tools to do it.

Can I install it myself?

ReadyLIFT recommends a certified mechanic and says to read the instructions fully before starting. The install sheet and ReadyLIFT's estimated install time for this exact kit are on this page.

Looks great and tube design is heavy duty.

So far great product and looks great. Love the way it looks on my 2019 Chevy Tahoe 4x4.I have a 5 inch lift with 20 inch Moto Metal wheels with a -24 offset. Best looking upper control arms on the market right now. GREAT PRODUCT!!!!

Great UCAs

I bought this over 3 years ago and I am happy with the purchase I made. They have given me plenty of life and hope they can give me many more miles once I replace the boots.

Better than OEM

Easy to install, I was even able to replace without removing strut. It is tricky but can be done. The ride is much better than OEM

A must have if using a leveling kit

Great product, well made solid tube. Very easy to install. I was able to install without removing the strut assembly. It is a bit tricky but can be done.

Great purchase

Was able to take out camber bolts without taking the strut out. Can be a little tricky, but with some patience it can be done. Great product.

Awesome product

Bought and installed these two months ago truck rides like factory even with the 2.5 leveling kit installed improved angles dramatically

Needed upgraded for leveling or lifting

Control arms are well built and finish holds up against scratching and chipping. Works with 2” to 6.5” of front lift. I have these on my 2” leveled truck after about 6 months the factory stamped steel ones started going out, have had these on for about a year and have had no problems. Would recommend them to anyone to use with leveling kit or lift kit

Good look

After install I was informed the control arms still didn’t eliminate the hard flex on my ball joint, currently looking for other ideas to alleviate the flex on my ball joint. Other than that it still slightly rubs my tires but so much better than the stock.

Upper control arm ball joint

Nice design but only issue I’m having is the rubber boot on the ball joint came undone and can’t get it to go back into place

Great upgrade with one frustrating flaw

Bought these for my leveled Silverado. Good construction, greasable ball joints. Fit perfectly but one flaw. The ball joints have no allen wrench recess to stop them from spinning. This is complicated by Readylift including a locknut that immediately grabs the ball joint stud before seating. Solution is to use a regular M12 bolt to seat the joint, then remove it and install the lock nut.
