TDracing19 Posted December 2, 2020 Report Share Posted December 2, 2020 What are the spec shocks for the legacy cars? QA1 was the previous ones I remember using but according to the Allison Legacy website, they’re using AFCO. Quote Link to comment Share on other sites More sharing options...
JRfan Posted December 2, 2020 Report Share Posted December 2, 2020 (edited) From the most current Lone Star Legacy rule book Shocks Only one, nonadjustable, stock, steel, QA1 7564, which is a 75 Series Steel chrome plated, twin tube shock with a 6" stroke and a #4 valving rate, or the Pro Shock SB 64, which was legal under the original Allison Legacy rules and prior editions of the Lone Star Legacy rules, is permitted per wheel. The only adjustable device allowed on the shock is the spring adjustment nut. No revalving or altering of internal components of stock shocks permitted. No custom made or “tiedown” shocks permitted. 1. Springs: Only 17/8” inside diameter, 10” long, steel coil over springs permitted. The spring must be mounted in coil over form over the shock. 2. No sway bars on the front or rear permitted. But check with Jason Simental “Getzum” on here for clarification.

getzum Posted December 3, 2020 Report Share Posted December 3, 2020 The only other approved shock as of now is the Afco 1564 but you will have to purchase their hardware kit which can get pricey. I've been taking to a person from Bilstein shocks about a replacement shock. I believe the pro shock hardware kits are interchangeable with Bilstein so that helps keep cost down. No decision has been made yet on approving Bilstein just yet. Quote Link to comment Share on other sites More sharing options...
JRfan Posted December 3, 2020 Report Share Posted December 3, 2020 So are the QA1s not approved anymore? Quote Link to comment Share on other sites More sharing options...
getzum Posted December 4, 2020 Report Share Posted December 4, 2020 (edited) Pro shock, QA1 7564 and Afco 1564 are the only approved shocks. Edited December 4, 2020 by getzum Quote Link to comment Share on other sites More sharing options...
