No. Because the coil spring is already mounted and pre-compressed on the strut body, you can bolt this in without a spring compressor — that's the main time-saving advantage of a loaded/complete strut assembly over a bare strut.

No. The upper mount, bearing plate, and bump stop are not included. You'll need to transfer your OE hardware or buy a separate strut mount kit. Check whether your existing mount shows wear — replacing it during this job saves you from pulling the strut again later.

PRT is an OE-tier aftermarket manufacturer producing gas-charged, dual-tube struts to OE dimensional specs. Ride quality and durability are comparable to KYB Excel-G and Monroe OESpectrum in the same price tier. PRT is a strong value pick when you're doing all four corners or working on a higher-mileage vehicle where premium-tier pricing isn't justified.

Yes, provided you select the correct part number for your specific year, make, model, trim, and any factory suspension package (sport, touring, AWD, etc.). Spring rate and free length are matched to OE specs for that application. Do not mix assemblies between trim levels — spring rates differ and ride height will be off.
