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.
- Experience Power and Versatility: Our strut spring compressor has 9921 lbs/4500 kg load capacity and is perfect for motorcycles, cars, SUVs, and more. The strut spring compressor kit is designed for shock absorber spring removal, including MacPherson strut and conical springs.
- 3 Interchangeable Yokes: With three yoke options, our spring strut compressor fits various vehicle models: Gold: 2.6-4.9 inch spring holder (compression range: 2.6-11.8 inches); Black: 3.4-6.3 inch spring holder (compression range: 3.3-12.8 inches); Silver: 4.9-8.3 inch spring holder (compression range: 3-12.6 inches).
- Safety Comes First: With our coil strut spring compressor, your safety is guaranteed. The safety tongues prevent the springs from detaching, while the protective sleeves protect against scratches. You can use the hex wrench to fasten the bolts securely. Rest assured that our triple-layer safety feature allows you to operate worry-free.
- Extreme Hardness: Crafted from #45 steel, our fork strut coil extractor tool undergoes heat treatment for superior hardness. The threaded rod's resilience handles extreme pressures, and the yokes are fortified to withstand fractures and bending.
- Compatible with 7/8" Socket: Use the 7/8" socket to compress the hex bolt and perform shock absorber spring disassembly directly on your vehicle. Remember to lubricate threads, avoid impact wrenches, and select optimal clamping positions.
- 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

- 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
