Use the Saginaw style on early cars and Federal or TRW style on later cars. CVF brand power steering pumps also work well with these racks.\u003c\/p\u003e \u003cp\u003eFor Gen 3 Hemi swaps, the stock Gen III pump puts out too much pressure for the QA1 steering racks. Several companies modify new and used pumps at a reduced pressure (in the range of 1,100 -1,300 psi), including\u003cspan\u003e \u003ca\u003eBouchillon Performance\u003c\/a\u003e\u003cspan\u003e and\u003cspan\u003e \u003ca\u003eHolley\u003c\/a\u003e.\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003eHow do you convert to a Manual Steering rack?\u003cbr\u003eIf you want to use a manual rack, use Speedway PN 91034344 or equivalent. The QA1 K-members features pilot holes for manual rack mounting. You must drill these out. One of the holes overlaps and you’ll need to use a step drill. The manual rack also requires a different steering u-joint to work with the 9\/16-26 spline.\u003c\/p\u003e \u003cp\u003eIf you want to use the power rack, some customers use a closed-loop system instead of switching to a true manual rack. This provides the faster ratio (2.75 turns lock to lock vs 3.5 on the manual) without a power steering pump.\u003c\/p\u003e \u003cp\u003eWhat spindles are used with these kits?\u003cbr\u003eQA1 spindles start as Mustang II components and have modified steering arms. You cannot use standard Mustang II spindles. We offer both standard height and 2″ drop spindle systems. Drop spindles require 18″ or larger wheels and disc brakes at least 12″ in diameter.\u003c\/p\u003e \u003cp\u003eWhat is the ride height range for standard versus drop spindles?\u003cbr\u003eThe ride height range for standard spindles is 0-2″ lower than stock and the drop spindles provide 2-4″ lower than stock. Drop spindles require 18″ minimum diameter wheels and 12″ dis brakes to provide room for the steering arm and outer tie rod end.\u003c\/p\u003e \u003cp\u003eWhat brakes options are available for these systems?\u003cbr\u003eMost front brake kits for Mustang II spindles will work. For the front, we offer several Wilwood disc brake options. Wilwood rotors are dilled for Mopar 5 x 4.5″ and 5 x 4-3\/4″ bolt patterns. If you choose to use drop spindles, your discs must be at least 12″ in diameter.\u003c\/p\u003e \u003cp\u003eWhat parts need to be welded during installation?\u003cbr\u003eQA1’s Mopar front suspension systems are a complete bolt-in installation with the exception of the steering column u-joint. After shortening the steering shaft, you must weld the u-joint to the shaft.\u003c\/p\u003e \u003cp\u003eWhat headers fit with these front suspension kits?\u003cbr\u003eKeeping original equipment or factory high performance exhaust manifolds are both options.\u003cspan\u003e \u003ca\u003eTTI\u003cspan\u003e \u003c\/span\u003e\u003c\/a\u003eand\u003cspan\u003e \u003ca\u003eDoug’\u003c\/a\u003e\u003ca\u003es Headers\u003c\/a\u003e\u003cspan\u003e brands are also frequently used.\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e\n\u003cspan\u003eDrop Range: \u003c\/span\u003e\u003cspan\u003e2in. to 4in.\u003c\/span\u003e\n\u003c\/li\u003e \u003cli\u003e\n\u003cspan\u003eStreet or Drag Performance: \u003c\/span\u003e\u003cspan\u003eStreet\u003c\/span\u003e\n\u003c\/li\u003e \u003cli\u003e\n\u003cspan\u003eShock Valving: \u003c\/span\u003e\u003cspan\u003eDouble Adjustable\u003c\/span\u003e\n\u003c\/li\u003e \u003cli\u003e\n\u003cspan\u003eSpring Rate: \u003c\/span\u003e\u003cspan\u003e400lb\/in.\u003c\/span\u003e\n\u003c\/li\u003e \u003c\/ul\u003e","brand":"QA1","offers":[{"title":"Default Title","offer_id":45259029282974,"sku":"SS-52347-D400","price":5718.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0696\/7515\/5614\/files\/QA1_52347-D400.jpg?v=1748754250","url":"https:\/\/pegasuspowersports.com\/products\/qa1-52347-d400","provider":"Pegasus Powersports","version":"1.0","type":"link"}
