Wujexuhe Rear Suspension Bump Stops 5.31" (4pc) — OE 13330714 Rubber Coil Spring Insulators for Chevrolet, Buick, Cadillac — Reduc

Wujexuhe 4-piece rear suspension bump stop set (5.31", OE 13330714) is a direct-fit rubber coil spring insulator designed to restore rear suspension travel, reduce harsh bottoming and cut noise on compatible Chevrolet, Buick and Cadillac models.

This set of four rear suspension bump stops is engineered as a like-for-like replacement for worn or missing coil spring insulators. Manufactured from high-quality rubber, each unit cushions the suspension at full compression, helping prevent metal-to-metal contact and reducing shock impulses transmitted to the chassis. The parts are made to match OE dimensions for straightforward installation and long-term service life.

How does the Wujexuhe bump stop improve ride stability?

By absorbing energy when the suspension reaches its travel limit, the bump stop limits violent impacts and reduces vibration passed into the vehicle body. This makes handling feel more controlled at the extremes of suspension movement and reduces noise from hard stops.

• Prevents full shock compression and metal-to-metal contact
• Dampens impact forces to lower vibration and noise
• Helps maintain predictable suspension response during heavy loads

What are the construction and durability features?

Wujexuhe bump stops are molded from durable rubber designed to resist splitting and wear under repeated compression cycles. The robust material tolerates road debris and exposure while retaining shape and cushioning properties over time.

• High-quality rubber compound for long service life
• OE-style dimensions to ensure consistent fit and function
• Resistant to cracking, abrasion and routine environmental exposure

Is installation difficult and what’s included?

The kit includes four rear suspension bump stops intended as direct replacements; installation is typically plug-and-play for mechanics and experienced DIYers. No specialized tools are required—remove the old insulators and seat the new units into the spring perch or shock mount per vehicle service practice.

• Package contains 4 rear bump stops (5.31" each)
• Precision holes and tabs match OE locating points
• Simple swap-in replacement—no special tools necessary
