Designed for drag race only!!! Brake kits used different braket mount bolts make sure your ordering the correct insert for your spindles.

TRZ's 1978-1988 G-Body Stock Height Spindles are constructed from billet 6061 aluminum and CNC machined with a heat treated stainless steal spindle. The spindles will bolt on to your existing control arms or to TRZ Chromoly Tubular Control Arms. Designed and proven in drag race applications. They improves bump steer by putting the rod ends closer to a straight inline with the ball joints. With TRZ's aluminum spindles with hardware weigh in at 11 lbs. reducing front end weight.

TRZ also make a 1.5 in. drop spindles for use with early GM disc brake kits.(1964-1972 Chevrolet Chevelle, 1967-1969 Early Camaro, 1964-1974 Nova). And a 2 in. billet aluminum drop spindle.

TRZ steering arms have two adjustment holes in them. The closest holes to the spindles should be used for drag racing, inner holes lack some radius, but are more stable. (steering is not as touchy) The outer holes are designed for street driving to gain about 15% more steering radius. Adding the steering arms to the drop spindles are a great setup and helps with the bump steer geometry. The stock arms are angled and the TRZ Motorsports are straight, allowing the rod ends and ball joint to better align. The closer you can get the rod end side of the rack to be in line with the ball joint the less bump steer you will have. The rest can be eliminated with a bump steer kit.

Features:

  • 1 pair of stock height billet 6061 spindles (built using 17-4 Heat Treated Stainless Steel Spindle Pins), 1 pair of TRZ billet 6061 Steering Arms, and pertaining hardware
  • Stock Height Spindles & Steering Arms that will use stock-type drag race brake kits. (**This does not include any brakes that fit the late model S10/ Blazer with factory 2-Piston Calipers)
  • Weight for 1 pair of spindles, steering arms, and hardware is 11 pounds

Notes:

  • Brake Kits that will fit these spindles (NO Brakes Included): Strange B4122WC, Strange B4122WC2, TBM-001-0197, TBM-001-0272-1, Wilwood 140-1033-BD, and Baer 4301456C
  • Bump-Steer kits will be necessary. Our steering arms lengthen the tie-rods to help achieve proper Bump-Steer, as well as use a 1/2 in. straight hole to make your life easier.

Caliper Bracket Mounting Bolt Size Selection:

  • Strange Kits – Previous to September of 2021 used a 3/8-24 thread / Current kits use a 7/16-14 thread.
  • TBM Kits – Previous to September 2023 used the factory 8mm x 1.25 thread / Current kits use a 3/8-24 thread.
  • Wilwood kits – Use a 3/8-24 thread. Note: Calipers brackets must be modified to use only 2 of the 3 bolts. You will need to cut the forward portion of your existing caliper bracket to clear the spindle.
  • Aerospace kits – Use a 3/8-16 thread. You will need to source some 3/8-24 bolts to replace your existing hardware.
  • Physically measuring the current bolt size you have is better than guessing. If you cannnot meaure, you can choose the 8mm size, then drill and tap as you did with your factory spindles.
  • If you are ordering a brake kit from us on the same order, we will verify we send the correct size insert.
  • New inserts can be purchased for additional $60
