The 33-104652 shock uses a high gas pressure monotube design, a 46mm piston, and fixed valving tuned for controlled compression and rebound response. For Chevrolet K30 and GMC K3500 rear suspension setups with 2-2.5 inch lift, this shock provides the length and mounting style needed for custom or modified suspension geometry. This part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eExcessive rear suspension travel after a 2-2.5 inch lift\u003c\/li\u003e\n\u003cli\u003eInconsistent damping response from worn shock absorbers\u003c\/li\u003e\n\u003cli\u003eRear axle control issues on lifted Chevrolet K30 and GMC K3500 trucks\u003c\/li\u003e\n\u003cli\u003eShock length mismatch in custom suspension setups\u003c\/li\u003e\n\u003cli\u003eReduced ride control from aging monotube or twin-tube units\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify collapsed and extended length before installation to confirm suspension travel clearance. This shock uses eye-to-eye mounting with 5\/8 inch upper and lower eye bushings, so confirm the mounting points match the vehicle and lift height. For best results, compare the rear suspension geometry on your Chevrolet K30 or GMC K3500 against the listed dimensions before final assembly. Fits 1977-1986 Chevrolet K30, rear.
