Condition
Some customers and/or technicians may comment on a small amount of grease seepage from a brass or gold colored fitting located at the bottom of the strut assemblies. Note: At first glance, this may appear to be a fluid leak.
The 5th generation Camaro Z/28, as well as the 6th generation Camaro ZL1 1LE, employ a different type of strut than other traditional car and truck lines. These struts are specifically designed and tuned for the precise vehicle handling that these vehicles are capable of.
Cause
This condition may be caused by a vent allowing breathing within the damper body. There is no oil within this chamber but there is some grease on the inner walls of the housing that keeps the insert tubing lubricated against the component’s bushings. As air enters and exits this vent, it is normal to have small amounts of this grease exit the strut. This is actually part of the natural operation of these struts.
Correction
No strut replacement is required for this condition listed above.

- No adaptors required
- Heavy duty acme thread
- Versatile mounting options
- Multi-position hooks
- All steel construction
- 4.5 Ton Hydraulic Load Capacity: The hydraulic jack has a 4.5 ton load capacity, and the rated compression force is 1 ton. Our coil spring compressor is great for various vehicle types, including sedans, SUVs, off-road vehicles, and pickup trucks. Perfectly suited for spring disassembly and shock absorber maintenance.
- Versatile Clamping Options: Our spring compressor comes with two clasps for the utmost versatility. The small spring clasp accommodates sizes from 4.3" to 5.1", while the big spring clasp caters to 5.5" to 6.7" sizes. With a maximum compression stroke of 12.6"/320 mm and featuring 8 positioning holes on the column, you can easily adjust the clasp position to match different spring heights.
- Stable Suspension: Prioritizing safety and convenience, our coil spring compressor features a stable suspension system that prevents bouncing due to spring tension. It halts at the current position and only descends slowly when you engage the pressure release valve.
- Safety Assurance: The strut spring compressor provides multiple-layered protection: a 39.4" extended safety chain to secure the springs, an additional stable locking mechanism, and a safety tongue on the clasp to prevent spring detachment accidents. The H-shaped stable base ensures minimal wobbling during operation. For added security, two pre-drilled holes allow you to anchor the compressor to the ground.
- Premium Material Construction: The hydraulic jack boasts a leak-proof hydraulic pump and a dampened hydraulic rod for seamless lifting and lowering. The Q235 reinforced steel column and the ductile cast iron clasps provide unparalleled durability to withstand extreme pressures, ensuring heavy-duty springs without risk of breakage or bending.
- Works on Most Vehicles: This heavy-duty spring compressor tool set by Orion Motor Tech repairs bent and damaged parts and performs the necessary suspension maintenance on the MacPherson struts and springs found in most small and medium-sized cars
- Secure Compression: Acme-threaded rods ensure a firm grip on springs, while built-in detent pins securely lock them in place, providing reliable, non-slip compression for safe and precise work
- Wide Compatibility: Working with your manual or power tool's 1/2-inch square drive or 13/16-inch hex sockets, our Acme rods and end pieces offer a 10.5" range, wider than the competition to work with more vehicles
- Built to Last: Our pair of heavy-duty strut spring compressors boasts high durability and corrosion resistance under even punishing use thanks to their heat-treated steel construction, black oxide finish along the threaded rods, and zinc-coated heads
- Compact & Portable: This hock spring compressor tool set comes with a blow-molded case, keeping parts organized and easy to carry, store, and access, so you're always prepared for your next repair job
- 【DOUBLE-RETENTION SAFETY SYSTEM】 Secure hook jaws grip the coil from both sides, while the adjustable holder connects the two compressors to help maintain alignment and reduce the risk of the jaws shifting or disengaging during compression.
- 【HEAVY DUTY 2,645 LB CAPACITY】 Built from durable carbon steel, this heavy duty spring compressor provides a 2,645 lb (1,200 kg) rated capacity for demanding automotive suspension work while helping resist flexing and deformation under load.
- 【FOR STRAIGHT COIL SPRINGS ONLY】 An ideal solution for various vehicles, including trucks and large sedans. Avoid strut compressors with flimsy hooks that cause slippage or safety hazards. Fits spring wire up to 0.8" (20 mm). Not compatible with tapered or variable-diameter springs; verify spring dimensions before use.
- 【WIDE ADJUSTABLE RANGE】 The suspension spring compressor offers a 2.7–10.6" (70–270 mm) jaw capacity, while the adjustable holder fits coil diameters from 8.6–12.2" (220–310 mm), providing flexible positioning for compatible straight springs.
- 【CONTROLLED 19 MM HEX DRIVE】 Tighten the screw compressors evenly from side to side with a 19 mm socket or wrench for controlled spring compression. Always apply grease to threads before use. (Ensure even pressure on both sides — uneven force may cause tool detachment.)
- Designed to increase the capacity to hold and compress any type or size of struts and springs
- Equipped with 14" holding vice and 20.5" high which can be adjusted to fit and compress any types of strut in upright or upside down positions
- One man operation system that takes less than 10 seconds to compress spring
- Universal adjustable holding arms prevent spring from popping out
- Patented Rack and Pinion gear and patented Double Clutch Disc systems
