Mopar suspension parts, tested on the street and the track.
Bergman Auto Craft draws on decades of experience with classic Mopars to offer the best combination of in-house and proven manufactured parts. SPC, Bilstein and Fox are available alongside the BAC line. We test every part we sell on the street and the track, so we can give you real-world feedback before you buy.
Parts picked to work together, not bought one at a time
A lot of Mopar owners buy upgrades blind and end up with parts that fight each other. Every piece in our front suspension kit was chosen to match the others, then proven on the street and the track. The key parts are also sold on their own, so you can upgrade over a few seasons and still end up with a matched front end.
Start where your car needs it most
- Complete front end: the BAC Street Front Suspension Kit.
- Easy first step: the Stage One Suspension Kit.
- Control arms: SPC/BAC 2.0, SPC/BAC 1.5 or QA1 upper arms.
- Ride and roll: torsion bars, Fox or Bilstein shocks and matched sway bar sets.
- BAC products are designed by Bergman Auto Craft and manufactured in the U.S.A.
Less body roll
Double adjustable upper control arms with taller ball joints shorten the moment arm, so the car stays flatter in corners.
Easier alignments
A wide adjustment range on the upper arms and adjustable strut rods makes alignment simpler and suits a wide range of setups.
Spring and shock matched
Torsion bar rate is chosen for modern handling and matched to the monotube adjustable shocks in the kit.
No slop in the steering
New pitman arm, 11/16″ tie rods with solid steel sleeves and a roller bearing idler arm remove the play you feel on center.

How they drive now
“These upper arms are a must for easier adjustment and increased positive caster. Larger torsion bars, Bilstein rear shocks and a few other suggestions from Peter, and my Charger performs awesome on street and the track.”
Steve R. · Charger“I have a 6.1 Hemi in a 72 Duster with stock K member, 1.08 torsion bars and Brembo brakes on stock spindles. All the parts fit perfectly without any modifications.”
Pete A. · 1972 Duster“My Duster has the full arsenal of Bergman Auto Craft steering (Borgeson), suspension (SPC, Bilstein, Delrin, torsion bars) and brakes (custom hubs with Viper Brembos), but in the end the best part of the car is how it drives like a modern muscle car, yet it’s not harsh.”
Brian U · Duster“The fit and finish of the parts is excellent. With boxed LCAs, new pivot pins, upgraded T-bars, and SPC UCAs the car handles fantastic.”

Suspension FAQ
Where should I start?
The Stage One Suspension Kit is the easy first step: it firms up the lower control arm triangle and improves alignment geometry. The BAC Street Front Suspension Kit covers everything from the K-frame out.
Can I build it in stages?
Yes. The key parts of the kit are also sold on their own, so you can upgrade over a few seasons and still end up with a matched front end.
Why Delrin instead of rubber or poly?
Delrin bushings are stiffer and quieter than polyurethane, with very little deflection under load. Our pivots are hand-fitted to them, so no inner or outer shells are needed.
Will the A-body rear sway bar fit my car?
The A-body rear bar requires 3″ axle tubes. It does not fit the 7-1/4″ rear end.
What do I put in the order notes?
Your year, body and engine. For the Stage One kit and the Lower Suspension Package, choose your car on the product page.
Can I get help choosing parts?
Yes. Call, text or email Peter almost any time at 516-384-6438. You get the person who built the kit, not a call center.
