1st thing to do is read over the entire instructions

Two styles of IFS are available.The Heavy Duty (HD) or Standard (STD)


LOCATING THE FRONT AXLE CENTERLINE4

The first thing to do is mark/scribe the axlecenter line on both chassis rails by measuringfrom the front of frame rails. Make surethe rails are not bent & straighten where pos-sible. Now you can remove the stock compo-nents from the chassis. Removing the front clipmakes this job much easier, but is not required.

1If you never liked the position of the wheel in thefender opening, this is your chance to center thewheel. With a fender on the vehicle and a mountedwheel and tire, center it where you like it best andmark that centerline on the rails.

2

WHAT YOU NEED TO KNOW BEFORE YOU STARTOur UNIVERSAL FRONT-STEER WELD-IN IFS INSTRUCTIONS cover the installation on early narrowchassis and later wide chassis for both cars and pickups. For narrow width frame rails, the upper towermounts on the outside of the chassis, and for wider frame rails, the upper towers mount on the inside of therails. They are both installed the same way on-center to your front axle centerline that you will mark on theoutside of your frame rails, before you disassemble the front suspension. The secret to a perfect installation(for either inside or outside mounted towers) is to mark a centerline through both upper towers and on bothends of the lower crossmember (before you install them). This way all your components will perfectly alignto the front axle centerline on your rails, directly under the centerline of the upper towers. For a perfectinstallation before the tac-weld phase, we recommend measuring from the front diagonally in an "X" fashionacross between the upper and lower A-arm cross-shaft holes to make sure your work is square before thefinal welding.

If the suspension is missing, we recommend installing a front fender, and position a mounted wheel and tirein the center of the wheel well opening. Now you can mark the front axle centerline on the rails. Somevehicles from the factory had wheels that were not centered. This is your chance to get it centered. Withwheels pointed straight ahead, check the wheel position in the fenders. It is much easier to install your newIFS kit with the front sheetmetal-clip removed, however it is not mandatory. In some cases you may have toremove your stock crossmember or trim some of it to install the front mounted rack. Leaving the stockcrossmember will double the strength of your front frame rails.


GRIND ALL AREAS CLEAN WHERE COMPONENTS WELDTO THE RAILS

5

Using the upper tower asa guide, to where it will bewelded on the chassis,grind the areas clean. Ifyou are installing boxingplates, you'll need to grindclean the top and bottomsurfaces and under thetop edge and inside thebottom edge of both railswhere the welding willoccur.

3 4

For eitheroutside orinsidemounteduppertowers, alignthecrossmemberto the axlecenter linescribed onthe outsideof frame.

ä

5

OUTSIDE MOUNTED UPPER TOWERS

Before tac welding, check your work and make sure it issquare. We recommend measuring in an "X" fashion from thefront across between the upper and lower A-arm cross-shaftholes, when your dimensions are identical, make the tac weldand remeasure.

INSIDE MOUNTED UPPER TOWERS6

Before you start the installation, mark acenterline through both the upper tower andlower crossmember outer lip as shown below.Both components must align to this axlecenterline on the rails. Scribe it on the outside ofthe rails.

Check the fit of the boxing plates inside the framerails. The boxing plate butts against the stockcrossmember, and just inside the top and bottomrail as shown.

The boxing plate needs to fit inside the framerails with at least 1/2 to 3/4 of the boxing platethickness sticking out past the rail edge. Fill thecreated 90° corner with the final weld.

ROUTING THE STEERING LINKAGE

The steering linkageroute is designed toclear block huggerstyle headers or '70-81 Camaro mid-length applicationheaders. (exceptHooker Headers).The route is designedto go under the sidemount engine mounts(as shown).

18 19

Using the headers mentioned, the route will requireonly 2 U-joints as shown. Other style headers mayrequire 3 U-joints and a support bearing.

20

Steering stops gotoward the rear.

Grease all (4)bushings inside andout, along with thecross shaft and theholes in A-arms andin the crossmemberon each side.Install the 4 ure-thane bushings asshown.

21

22

Find these parts to assemble the lower A-arm. The lower balljoints come pressed-in.Refer to the HARDWARE PAGE 3 forfastener sizes. The lower A-arms need tobe installed on crossmember first.(Right A-arm shown below)

ä

ASSEMBLING THE LOWER A-ARMS


9INSTALL LOWER A-ARM - Con’t

24

Use only a plastic mallet or rubber hammer to tap the shaft throughthe first 2 bushings. Then, install a 3/4-inch diameter washerbetween the bushing and the crossmember. Continue to tap thepivot shaft through the crossmember.

As the pivot shaft meets the other side of thecrossmember, install another 3/4-inch diameter washer.

You should have one washer on each side of thecrossmember.

2627

25

Continue tapping the shaft through the last 2 bushings,then stop with about 1/4-inch of shaft sticking out.

Use the aluminum capshaft screw (5/16NF X 3/4countersunk) to tap the shaft through the last 1/4-inch.


10

INSTALLING UPPER A-ARMS TO CROSSMEMBER

2829

Install the aluminum end caps and Loctite both5/16 NF countersunk flathead screws in eachend. Using an Allen wrench on each end of theshaft (end caps) will keep the shaft fromturning.

Next, find the 5/16NC X 3/8 set screw, Locktite it andinstall as shown in lower A-arm cross shaft. Do not usethis to hold the shaft tight to install end caps.

30

The longer arm of the upper A-arm goestoward front of the car.

Find these parts to assemble the upper A-arm.The balljoint drops in and is held by four 1/4-20X 3/4-inch bolts and Nylock nuts (torque to 15ft. lbs.)

31Applygreaseon boththeupper A-arm pivotbolts.Install atubularsleeve on each end. Use the shims providedbetween the sleeve & upper tower to eliminateany end play. Install bolts finger tight until align-ment.

32

33 35

Start by loading the rear A-arm bolt as shown, with 1sleeve, 1 thick washer & 1thin washer. Eliminate allfront-to-rear movementusing the washers as shims.

Find these partsto assemble theupper coilovermount. Refer tothe HARDWAREPAGE 3 forfastener sizes.

INSTALLING COILOVER BETWEEN A-ARMS

Check thespring pre-loadon your as-sembled coilover.With the top of thespring seated intothe upper collar,thread the lowercollar with stainlesswasher (next tospring) against thespring. Using the spanner wrench enclosed, thread thelower collar 3/4-to 1-inch up the threads and tighten thecollar lock nut against the lower collar.

Find these bolts to install the coiloverbetween the lower A-arm & upper tower.Refer to page 3 for fastener size andlocation.

Now you can install the coilover in the lower A-arm. Besure to install a bushing on either side of the coiloverwhen installing the 1/2NC X 4 1/2-inch bolt. Use threadlocker and install the Nylock nut. Torque to 60 ft. lbs. Ifyou’re installing a sway bar don’t forget the “L” bracket,see #40 & #41.

The optional brake kit provides all you’ll need tochange to a disc/drum system. Notice, the propor-tioning valve goes in the line to the rear drums.Replumb the brake lines by plugging the rear of theoriginal “T”. The new line to the rear goes from therear port of the m/c through the proportioning valveand reconnects into the old rear brake line.

Steering linkage,modifing existingcolumn or new columnare optional.

When installing your steering linkage U-joints,make all U-joint connections as shown! Theconnecting shafts that enter the U-joints shouldbe mounted flush on the inside! Your steeringcan be severely limited or lock-up if the con-necting shaft protrudes into the U-joint travelarea! Loctite and tighten all set screws in the U-joint as tight as possible and lock in place withthe jam nut and check them occasionally.

STEERING AND BRAKE INSTALLATION TIPS13


The urethane bushed link kit provided withthe optional sway bar goes through thebracket on the front of the lower A-arm. Thehead of the bolt should point toward theground when loading the urethane bushings.A bushing goes on each side of the sway barand on each side of the A-arm bracket.

54

After the ends of the sway bar have been attached to the lower A-arms &tighten just enough to compress the bushings on top & bottom, install theshaft bushings & swing the sway bar up to the bottom of the frame asshown. The forward existing hole on the frame lip will line up with the fronthole in the bracket. You’ll need to drill a 3/8-inch hole for the rear of bothbrackets.

The long 3/8 boltgoes between thelower A-arm & tierod

53

Install the raised endof the urethane bush-ings into the holes asshown.

51

INSTALLING THE OPTIONAL SWAY BAR14


LAST - Set the toe-in. Always measure between thesame tread on each tire. We recommend setting aboutan 1/8-inch toe-in when you’re finished with theinstallation. First, you’ll have to measure the back (oftires) between the treads and then the front using thesame tread as the rear. When the measurementsmatch, then you can set the front tread 1/8-inch in.

FIRST - set camber toget to the alignmentshop. Align the upper A-Arms after the car isassembled and has allthe weight on thechassis. Using any typeof vertical level (ex-amples in photo), on therotor face, adjust upperA-Arm rod ends untilrotor is vertically level.

55

To remove all front-to-rear upper A-Armmovement, start withone sleeve next to eachrod end, and then usinga combination of thick orthin washers, shim asrequired (followingalignment specs below)to remove any extraspace on the rear pivotbolt only. Torque pivotbolts to 60 ft. lbs.

SECOND - set caster. With a magneticdegree wheel or a level on the base ofthe spindle, set caster from 1 1/2 to 4°.If using a level, mark bubble locationand make both sides the same. Adjustequal amount of threads on both rodends. To move upper A-Arm to rear goin 2 threads on rear leg. Recheck untilyou’re close. More caster will makesteering wheel return back to centerquicker. LAST - Recheck camber, re-adjust if necessary. Remove platformwhen finished.
