RJ Extreme Series 4-Link Kit


Product Description

This new 4-link system from Quarter-Max offers the most adjustability you can get in a weld on front chassis 4-link bracket. The bracket is made from .250” thick 4130 steel plate and cut in house on our water Jet. The bracket has Qty – 8 .500” top holes and Qty – 8 .500” bottom holes for optimal tuning adjustability. The .500” holes are .625” apart on center. The center of the top cross member to center of the bottom cross member is 15”.

We also offer .125” thick 4130 Doubler brackets for the top and bottom holes that weld to the 4-link bracket to increase the thickness around the holes to .375” 

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!

  1. Fantastic 4-Link Kit

    Posted by Doug Haas - Doug Haas RaceCraft Engineering on Dec 14th 2017

    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..
