Extreme Series 4-Link Kit
Our Extreme Series 4-Link System offers the most adjustability you can get in a weld-on front chassis 4-link bracket. These brackets feature qty (8) 1/2” top holes and qty (8) 1/2” bottom holes for optimal 4-link tuning adjustability. The 1/2” holes are 5/8” apart on center. Manufactured in house on our water jet machine.
We offer 2 different styles of weld-on chassis brackets. They are available in different heights/configurations to fit any chassis crossmember setup (the center of the top crossmember to center of the bottom crossmember):
• 13" notch spread
• 15" notch spread
• Material: 4130
• Thickness: 1/4"
We recommend using our 1/2” NAS bolt kits with these brackets for tight fitment and considerably less bolt movement than other systems. (sold separately)
We also offer 1/8” thick 4130 doubler plates for the top and bottom holes that weld to the 4-link bracket to increase the thickness around the holes to 3/8” for extra strength and longevity. Doubler plates are sold separately.
When mocking up and welding together brackets you should use grade 8 bolts. After all the welding is done you should ream the holes to correct size. Do not use a drill bit! We recommend using our 7 piece chucking reamer kit.
Purchased one of these kits for a customer for a new car being built. This is one of the very few kits that give you unlimited adjustability and is worth the cost. The quality of the pieces are as good as you can get. I rate the people at Quarter Max and especially Rickie Jones as top notch and would recommend everything they make..
